as a non-welder the one thing I've learned from all these welding videos (more so comments from these welding videos) is that no one knows how to weld.
Well, welding is hard. I'd say most people, even professionals, won't be that great at it. It takes a lot of practice to actually control the weld pool properly or even truly understand what you're seeing/doing while welding.
I do, I'm qualified in ship welding not in corded pipe welding though that is just pure madness using electric arc at about 90 amps usually, still think I know now about welding.
i’m no welder so it could be worse or anything but you’re exactly right. no one is explaining why, hate how youtube comments are full of people like this
There are many reasons why it’s wrong 1 the first rod was not prepped and tacking over and over is not welding 2 the second rod didn’t need the tacks on the end first. Could of just done a better job with the prep when the grinder was already out 3 welders have adjustments for a reason if your welding so hot that it looks like chewed bubblegum at the end because it’s falling out everywhere. Maybe turn it down a bit There is other stuff as well but I don’t really have the time to point out everything wrong with this. Just know it’s absolutely horrible and to even call it welding is a stretch
Why would a welder explain it? If a surgeon explained how to remove a tumor would you open up shop in your garage? If you want to learn how to weld there are more efficient ways than being told why this obvious display of "welding" is wrong.
@@l3LiTzI don't think you understand why we want an explanation. We are not asking for a guide or a tutorial on how to do it. We just want an explanation on why it's bad. We are curious on the reason why its not worth it doing it this way.
For those asking why this is wrong, here's an explanation: In the first weld (if you can even call it that), he effectively tack welded it, which is a very weak weld that serves to hold the pieces together while you do an actual weld. There was effectively no penetration, as you can see right before he grinds the tack off. Pause the video right before the grind wheel comes into view, and you can actually see the layer of the filler metal on top of the rebar. The second part is also bad f9r pretty much the same reason. While he didn't break it to show what it looked like inside, it still looked like little penetration. What happened here is he created a hole (or gap), and just filled that gap in.
Aber als Bewehrung darf das nicht benutzt werden, Schweißen ist da verboten, egal wie toll die Naht aussieht die Hitze verändert das Gefüge welches der Baustahl besitzt, das sind dann die Stellen an den Beton dann brechen wird.

As a welder I will say this: a welder is a state of mind. What he did in the video will do. It is not a ship that needs to be welded precisely. Especially since it is to be filled with concrete.
@@johnbecker3159well said. I am curious why they would weld rebar for concrete in the first place. There might be a few specific applications on bridges but usually rebar splices in concrete are just wire tied together and that this usually fine because the concrete is providing the rest of the strength in tying the two overlapping bars together. It seems like this video would be a expensive operation since I can’t imagine how much electrode was used to weld two rebars together and what is the reason.

As a welder, you want a solid fusion of the weld and the surrounding metal, this is why when buildings and bridges are welded, the beams are held apart and filled with high quality welds performed by a skilled practitioner. This basically makes it so that the columns aren't a bunch of H beams and I beams stuck together, but are more like one very big fused structure. One continuous mass of metal.
I guess I’m confused…Is that not what this guy is doing? Making two separate rods into one solid fusion? I’m just wondering what about his technique is so wrong that welders are flocking to the comments lol
@@Dragonaiis if you stick the two metal rods together with their flat ends and then weld, the welding doesn't fill the middle of the tiny gap between the rods, thus leaving an air pocket that blocks forces spreading evenly through the whole welded structure, it's the same with glueing two pieces of wood together: you always cover both sides of the two parts with glue before you put them together. Metal doesn't work like glue, thus you have to leave the gap and weld continuosly until the gap is completely filled.
@@Dragonaiis you're technically correct (the best kind of correct ^^) but why prepare a piece so masterfully and then do such a sloppy weld other than for creating engagement? Hahaha
For those who don't know, the first "welding" was just Tack-welds and are never ever ever meant to be used as a final solution... it's low energy bonding and just barely holds pieces together, and usually used to help stick pieces together before you do real welds. The second welding is just kinda bigger tack-welds, there is not enough electricity/heat to have a good bond because of the start/stop welding. You want deep enough penetration into the existing metal, not just all that surface and filler welds. Think of the metal like ice cubes, you want to really melt the ends and refreeze them to make it one whole piece, not just lick the ends of the cubes and stick them together. Then, beyond that, the purpose of rebar is to be flexible and malleable, so welding it will create a hard and non-malleable spot where it might want to crack and fracture instead of bend. So you probably need to heat it back up and slowly cool it down (with something insulating it) to bring back some flexibility. I'm not a professional welder, I've just done a lot of welding in my time on this planet, so the professionals probably have more insights.
i was on a job where they used thermite the same way they fuse ground cables together. we were doing an electrical sub station. every time i say that i’ve seen that done to rebar everyone always corrects me and says that i’m thinking of ground cables…. but i’ve seen them do the same exact thing to rebar before where they place the two ends together side by side and then they take a little mold which clamps over the rebar and then they stuff the mold full and light it on fire and it leaves about a six inch long round bar shaped chunk behind over the two ends. i want to say it was around 2009 when i saw this done and i was on four other sub station projects and never seen that done again since but i know it’s possible.
Engineers only work on new crap. They do not work on the crap they manufacture after its puts together when the real techs have to figure out their garbage
In general, what's wrong here is that the reinforcement in concrete experiences a much greater load than hammer blows. Therefore, in the foundation of a building, it will simply break because the welded joint is still more fragile than the rest of the metal. For a reliable welded joint, the reinforcement bars must be overlapped by about 20 centimeters and welded along the entire length of the overlap. Plus, you should heat the joint evenly with a blowtorch to relieve residual stress in the metal.
This steel has a high carbon content when welded at high temperatures, which causes it to temper and its hardness becomes very high, which causes it to break easily when welded. It is recommended that after welding, it be heated with a blowtorch to a temperature of 250 degrees and that the heated part be covered with plenty of construction lime, which will cause it to cool very slowly. This is called tempering the steel, but it is advisable to have it done by an experienced person.

As a Certified Stick Welder. The solution is in fact, Good enough. Rebar shouldn't typically be welded (Weldable Rebar is a specific thing you need to go out of the way to get). This video is better than 99% of the safety sandle welding videos ive seen
I also have my certs, and i can guarantee that that cobbed up goober of a weld would be sent back and you wouldnt get your certs if you sent that in for testing.
These are in fact the secret welding techniques of the Lost Tartarian Empire being revealed. I’m not sure how this guy knows this but it’s very impressive and procedurally correct.
I may be only a carpenter but I give you 3 points for the final weld. However... You pointed at it, which is an automatic deduction of 2 points and you've got a massive blowout which is a deduction of another point. Leaving you with zero points. Thanks you for playing, better luck next time
For all the people that want the explanation of how to do this properly: The second method is approxiametly correct, done with terrible technique and would not likely pass any sort of insepction performed by a CWI (Certified Weld Inspector) The term for this is a double bevel weld, or a v-groove; and what we are looking for is this to be a CJP. Complete Joint Penetration. Meaning the weld is repaired the steel to it's original strength. Not all rebar is weldable, you'll want ASTM A706 (not A615). the filler metal used must be as strong as the weakest material being bonded, In this case, you have two pieces of same material which has a tensial strength of 80,000psi. If stick/arc welding (SMAW) then an E8018 rod would be appropriate. If welding rebar to A574-50 (65,00opsi) then E7018 rod would be appriorate. If running MIG (GMAW) then your filler material should be undermatched as described above/as descibed by AISC D1.1 and D1.4 A UT or MT inspection is likely to be required if this method is followed. (Ulstrasonic testing/Magnetic Particle Testing.) these inspections reveal imperfections and sometimes require welds to be backgouged and refilled, and resinspected. As an expereinced fabricator, this is probably the weakest version of welding rebar, and he did not do it so it was aesthetically please. Usually rebar is buried in concreted. I would recommend avoiding the CJP and overlap two pieces of rebar by 6-8" and perfroming a flare bevel weld both top and bottom, sealing the ends. Avoid inspections. where the splice would be possibly weak, there are 2x steel, the weld strength is just safety factor added on top. Cheers! TLDR, i already know.

Wtf are you talking about? Rebar is literally only used in concrete forms where it is tied together with wire. Welding is infinitely stronger than tying and absolutely did not significantly alter the tensile strength of the steel.
You know they use friction welds for rebars right? The British Standards also states that the rebar must retain the same physical properties after being exposed to heat for a certain duration.
You couldn't be more wrong, ALL rebar can be welded, look up AWS spec for prep and welding, I use rebar all the time for may fab projects, mainly because of the look or textures provided, I worked many years(now retired) in iron construction building bridges over interstates.
Funny you mention that. I just took my finals earlier today which I had to do an open root groove weld. Had full penetration, good strength, looked pretty, and was relatively even. I’m satisfied with it and think I passed. Only problem is I started off a little weak but managed to fix it down the line. It was mig tho, not stick.
That there is ‘Jesus’ welding, as one of the old welders told me, for two reasons- 1, it’s holey, and 2, when the welding engineers and inspectors see it, they say “Jesus!” 😂😂
Yea of course that booger with more penetration holds more then the 7 tacs he put on the outside Real question is when will someone teach him how to weld properly

Dear friends, please note that ribbed rebar is used for construction purposes and in reinforced concrete, and exactly the welding point, no matter how strong the weld is, is the most fragile point of any rebar, and it is only with the forging method that the connection of two rebars reaches its true strength, and that The laboratory must also confirm it. Thank you 🙏
It would help if you didn't do low voltage tack welds and did an actual weld like how you added a ball to each end before welding them together... Just put the tip between them then strike an arc then fill the gap. No need for all the work, just use the tools advantages to your advantage.... 👍
No need for the pre weld. Bevel the edges. That way your weld has room to set into and you can grind the surface smooth so there is no place for the weld to snag on anything.
Umm, non welder here, but im pretty sure the electrode is supposed to penetrate the metal and fuse to make it stronger. The second way done, there is no fusion, no penatration, so a bad weld. Correct me if im wrong
This is a good video and example of what not to do. Always divet the bevel. If you add a button on the bevel after a full divet, it will stengthen the bond of the joint. I have been a rebar welder for 19 years. I retire next month.
I know a number of welders that would scream about using a grinder to "pretty up" your weld. But I was raised by the instructor for Ironworkers local 395, and he was one hell of an ornamental welder, one of the best. He even passed welding exray school the first try, which I understand is about impossible. He was an old American Bridge guy that just kept perfecting his craft.
The more I watch these unwarranted (but not unwanted) welding tutorials, the more I learn that a big part of welding is finding a way to form a cavity between the two parts for the material to flow into.

As a welder who welds everyday, this is the best welding technique I’ve seen in my 3 years of living.
As a Certified Stick Welder. The solution is in fact, Good enough.
Rebar shouldn't typically be welded (Weldable Rebar is a specific thing you need to go out of the way to get).
This video is better than 99% of the safety sandle welding videos ive seen
its not good enough
cold welds and almost zero penetration
ask for your money back
that certification you got is worthless
I also have my certs, and i can guarantee that that cobbed up goober of a weld would be sent back and you wouldnt get your certs if you sent that in for testing.
Welding is like making Spanish Paella, no matter how you do it, the comments always say it's the worst they have ever seen.

Just grind the tip on the rods,no need for prewelding the tip!
he is learning wrong wY but it time if no one is hurt be will learn i hope
Orrr just put a bevel in the ends of the rebar like normal welders?

I may be only a carpenter but I give you 3 points for the final weld. However... You pointed at it, which is an automatic deduction of 2 points and you've got a massive blowout which is a deduction of another point. Leaving you with zero points. Thanks you for playing, better luck next time

What happened 2 the 'old' welder then? Just curious 😂
@@AndrewBirch-o4q He's resting in the Hamptons.
As a former welder this is a decent weld (I took two welding classes in high school)
For all the people that want the explanation of how to do this properly:
The second method is approxiametly correct, done with terrible technique and would not likely pass any sort of insepction performed by a CWI (Certified Weld Inspector)
The term for this is a double bevel weld, or a v-groove; and what we are looking for is this to be a CJP. Complete Joint Penetration. Meaning the weld is repaired the steel to it's original strength.
Not all rebar is weldable, you'll want ASTM A706 (not A615). the filler metal used must be as strong as the weakest material being bonded, In this case, you have two pieces of same material which has a tensial strength of 80,000psi. If stick/arc welding (SMAW) then an E8018 rod would be appropriate. If welding rebar to A574-50 (65,00opsi) then E7018 rod would be appriorate.
If running MIG (GMAW) then your filler material should be undermatched as described above/as descibed by AISC D1.1 and D1.4
A UT or MT inspection is likely to be required if this method is followed. (Ulstrasonic testing/Magnetic Particle Testing.) these inspections reveal imperfections and sometimes require welds to be backgouged and refilled, and resinspected.
As an expereinced fabricator, this is probably the weakest version of welding rebar, and he did not do it so it was aesthetically please. Usually rebar is buried in concreted. I would recommend avoiding the CJP and overlap two pieces of rebar by 6-8" and perfroming a flare bevel weld both top and bottom, sealing the ends. Avoid inspections. where the splice would be possibly weak, there are 2x steel, the weld strength is just safety factor added on top.
Cheers! TLDR, i already know.
PS: I meant to include the Joint Designation - in the tail of the double bevel weld, it would read: B-U3b (for SMAW) and B-U3-GF (for GMAW)
Hey, thanks a lot for this. Very informative. I at least know what to look up now.
In the words of my Grandad, that weld looks like bird shot 😂
I'm not impressed either 😂 this welder sucks!😂 This welding looks like a snail wrapping itself around.😂
I think he meant bird shit.

"Hammered dog shit" is my go-to term for welds like this.

As a non-welder I can say that I find such videos really really great.......... because of the comments
As a musician, this was quite helpful. I will now weld my way to the 4th, 5th, 6th dimensions untill my body disintegrates and my body is scattered across different dimensions. After that i will weld myself back to the sate i was originally in. Thanks a lot!
That dabbing technique with stick is a clear sign of a worker that sqats to work with sandals on and may or may not have running water at home.

I just wonder how many inspectors pockets have been greased to look the other way when inspection of these joints comes due?
Are you talking looking the other way from the first example, or the second way?
The first way 😂 @@meversace
It's just rebar. It's not going on the space shuttle. Nobody cares.
I live in brazil. The architecture here is this bullshit you see and much worse. I'm still trying to understand how they think this is good. Mind you im from America and lived in America my whole life. I live here because I got married to a Brazilian woman. Which I'm happily married but the country is on some bullshit when it comes to the way they build things
I have observed about 50 k of these studs and it would not past bend test. Not a qualified way of welding .
The weld may look allright, but the strength of the bar is compromised due to the heat of welding. These bars cannot be used in any build!
They can be joined using thermite and still used for building
Wtf are you talking about? Rebar is literally only used in concrete forms where it is tied together with wire. Welding is infinitely stronger than tying and absolutely did not significantly alter the tensile strength of the steel.
You know they use friction welds for rebars right? The British Standards also states that the rebar must retain the same physical properties after being exposed to heat for a certain duration.
Sidewalks, shed slabs
You couldn't be more wrong, ALL rebar can be welded, look up AWS spec for prep and welding, I use rebar all the time for may fab projects, mainly because of the look or textures provided, I worked many years(now retired) in iron construction building bridges over interstates.
Nicely done. Pretty much the best-case practical fix in a less-than-ideal situation.
If I had presented a weld like this in my finals , I had never gotten my degree or my welding license.
... different times, I guess.
Funny you mention that. I just took my finals earlier today which I had to do an open root groove weld. Had full penetration, good strength, looked pretty, and was relatively even. I’m satisfied with it and think I passed. Only problem is I started off a little weak but managed to fix it down the line. It was mig tho, not stick.
That there is ‘Jesus’ welding, as one of the old welders told me, for two reasons- 1, it’s holey, and 2, when the welding engineers and inspectors see it, they say “Jesus!”
😂😂
So what you are saying is that a deep penetrative weld is stronger than tour bull crap tack welds? What a concept
haha good point
Yea of course that booger with more penetration holds more then the 7 tacs he put on the outside
Real question is when will someone teach him how to weld properly
I think he's showing the people that would call the four tack welds good enough not to.
I’m a welder myself and I can’t stand the stop start weld videos. Correct rods and correct amps and do it in one.
Duct tape would be stronger than those bull crap tack welds.
Super super excellent work 💯👏 congratulations 🎉
Anyone with a grinder can be a welder!

Нужно было острее заточить и шире фаску(кромку) снять и получилось бы тоже самое !!!
Он не ищет легких путей. Ещё, место сварки потеряло упругость арматуры в следствии термической обработки. Её после сварки нужно закалить слегка ))
Ну не знаю что оно там потеряло, у нас на гидроцилиндре ухо приваривали так же правда и острее все точили и сварщик проффесионал варил, 3 тонны на нем держится, пару лет уже служит все норм@@johnsmit557
as a welding student with ~6 months of experience, id say this is the best weld ive seen!

Не любую арматуру варить получится, есть та, которая варится, причем хоть как насри,, а есть которую хоть обварись, а держаться не будет, от сорта зависит
@@Александр-и6и7и Это потому, что в маркировке арматуры должна быть буква С - что значит она поддается сварке. Если буквы нет - только вязка.
Dear friends, please note that ribbed rebar is used for construction purposes and in reinforced concrete, and exactly the welding point, no matter how strong the weld is, is the most fragile point of any rebar, and it is only with the forging method that the connection of two rebars reaches its true strength, and that The laboratory must also confirm it. Thank you 🙏

Foi o que eu imaginei 😂😂😂
Depende que electrodo estaba usando.
It would help if you didn't do low voltage tack welds and did an actual weld like how you added a ball to each end before welding them together... Just put the tip between them then strike an arc then fill the gap. No need for all the work, just use the tools advantages to your advantage.... 👍
As a person with no welding experience at all I support this product 100%.
Weldable rebar has a lone "W" on it.7018 3/32 works well on these.

Miss my oldest brother ...
No need for the pre weld. Bevel the edges. That way your weld has room to set into and you can grind the surface smooth so there is no place for the weld to snag on anything.
A trained and educated welder would bevel before weld.
That is a ugly weld
Fea... y no es, perfectamente, recta!!!
Its truly amazing how much stronger it is when you weld it instead of tacking it 10 times.
Best weld I have ever seen, I mean I am blind but I assume so is the guy making this 👌
As someone who learned how to weld by welding, I’d say you also welded
Watching on video is amazing watching in real life might go blind 😂😂
As a non welder with a degree in welding I can say this is well welded.
I've been welding since 2 years old and i can say this is a decent weld. I turn 3 next year
Umm, non welder here, but im pretty sure the electrode is supposed to penetrate the metal and fuse to make it stronger. The second way done, there is no fusion, no penatration, so a bad weld. Correct me if im wrong
This is a good video and example of what not to do. Always divet the bevel. If you add a button on the bevel after a full divet, it will stengthen the bond of the joint. I have been a rebar welder for 19 years. I retire next month.
Yeh last comment it was 25 lmao
I know a number of welders that would scream about using a grinder to "pretty up" your weld. But I was raised by the instructor for Ironworkers local 395, and he was one hell of an ornamental welder, one of the best. He even passed welding exray school the first try, which I understand is about impossible. He was an old American Bridge guy that just kept perfecting his craft.
as a profesional human and also a part time person, i can say this is one of the welds i've seen
As a dude reading all the comments I can confirm those pieces of metal are stuck together now
As an Overwatch player, I can say that looking at the bright welding plasma hurts my eyes.
As a forklift driver I can confidently say from my vast experience and godlike status .. that was definitely a welder being used in the video 100%
Being the inventor of metal, I can attest this is top notch.
I have never seen a single welding video in which the welder is praised for his skills. I've learned that nobody actually knows how to weld
Man approached welding like soldering. Magnificent
As a seasoned expert in welding plastic I can confirm this is definitely the correct way to weld wood 👍🏻
Nice useful video brother 👌💯👏
I can honestly say that in 63 years, I’ve never needed to know how to do this and don’t expect to!
The more I watch these unwarranted (but not unwanted) welding tutorials, the more I learn that a big part of welding is finding a way to form a cavity between the two parts for the material to flow into.
Well I learned something today.
Buy longer lengths of rebar.
Gracias por video esa técnica llevo años haciéndolo pero por fin encontré a alguien que haga el mismo método.
