I made a newer, shorter version of this video using the same technique. It also shows the process more clearly. You can watch it here: ua-cam.com/video/2WGxAFi6EUM/v-deo.html
that de-rusting was the most satisfying thing ive seen in a long time
I’m guessing you’re new to the welding world?
25 years of experience tigging stainless, here is the best advices your going to ever hear about tigging a gap. Take your bad parts and toss them into the scrap bin and start over. Don't believe me try welding up a gap and see what happens. You will destroy your whole project when everything moves on you. Stainless pulles like crazy.
I’m just starting out tigging stainless, I purposely came on UA-cam today to try learn about tacking thin stainless, I’m struggling to tack without vaporising it, if I can manage to get the 4 tacks I’m away, but untill then I’m just blowing holes instantly. I’m finding the gap has to be absolutely perfect!, and even when I feel iv got the gap right I tack one side and instantly it’s pulled on the other 🙈
You would make a good welding teacher I’ve been welding around 13 years and I would recommend you to anyone your laid back and very knowledgeable nice channel by the way 🤙
Thank you for that! I’m wanting to starting building more cool projects and hopefully people can pick stuff up along they way and I can also learn from them.
If the gap isn't as severe as that but still wider than your filler rod, try flattening the wire out in a vice or with a hammer to make it slightly wider, I've used that before and it works a treat. You could also maybe try doubling up on the rods so you have double the rod width to help bridge the gap. Just a couple more ideas 👍🏻
Really enjoyed this video, and especially the one arc shot that you had exposed low enough to see your technique was really interesting. I saw that your process was: Add filler, back up a smidge, and then move forward to the next dab location. Very interesting!!
Really appreciate the care and attention that went into you producing this video. Very well put together! Thanks for sharing.
Nice work showing real situations. Perfect fit ups aren’t always possible or even practical. Good tips and nice cleanup on the work before welding. You’re quite a good fabricator. Thank you.
That’s some seriously clean metal. I spent about 3 hours yesterday cleaning up a trailer to weld and it still looked worse than what you started with.
Idk why I’m watching this I’m a very experienced tig welder but I’ll give you a like since I’m here.
Pro tip; practice walking the cup or weaving your gaps, it makes filling gaps much faster
Appreciate the like!
The technique he used minimizes distortion. I do the tacks at the corners like he did but then I just do stringers to fill the gap without letting the stuff get fully joined till it all cools down.
I would use 2 or 3 filler rods and just weave the entire gap to save time. Not sure if that is the proper way but whatever works. I would imagine the tack method keeps the heat affected zone down though so maybe that is the correct way.
I agree. This was painfully slow
you should warm him how much a pain in the ass walking the cup can be (fucking overhead) lol but if he can tig weld this good im sure he knows all about it :P first thing one of my instructors told me at the trade school i went to is he has seen grown mean cry from trying to learn tig haha he was about 65 years old himself and would admit he wasn't the greatest tig welder around.....stick on the other hand
When I was young I used to be a shipbuilder/welder. When we were stick welding heavy steel and there were sometimes gaps up to 30-40 mm. On a sunny day the sun might give you a hand as the temperature of the steel was rising, but normally we could not wait for that. So we would use a copper plate on the back as a form work and build up the weld.
A chill block!!!
I would break the flux off of arc rod and use it as a filler wire feeding it into the arc puddle. It worked to fill some of the larger gaps very quickly.
@@streetfighterguy1909 I am sorry to say that some guys did that, but only once. They were sendt home. They were warned about that at their welding courses. Those welds had complete lack of fusion, penetration and looked like a swiss cheese on x-rays.
@@kib2675 let me give it another run since it has been about 18 years since that old guy showed me that trick but I never remembered it having a lot of porosity. I'll toss something up today and review it again.
Good tip and I have been doing this for years. The multiple tacks are a great idea on thin metal as it reduces the length of time the heats stays in one place and therefore prevents blowouts and reduces warpage.
Tacks are deadly on code welds. ,,, Sorry gang. This is junk welding at it's best.
@@mathewmolk2089 Sorry, but not all of us work for NASA
I’ve have been a welder for a long time and that is how I was taught back in the 80s,good job 👍
Nice! Being at an extreme rookie phase with no instruction, I am amazed at the level of detail in regards to cleanliness and buffing in comparison to "burning it out" with a 6000 series stick rod. Cheers and thanks!
I had a 0.125-ish gap to fill around a cylinder. I started kinda like you with making bridges and then moved the pool from one piece, across the bead and onto to other. Pedal control was critical in the beginning, but it worked. The one problem I had was sugar on the weld itself. BTW, I'm glad that I'm not the only one who cleans the filler rod
Nicely done Justin, I am considering a TIG welder as my next major purchase. You did a great job of illustrating how to fill gaps and make them appear as though they don't exist. Thanks for sharing.
I would recommend it if you enjoy metal working for sure!
Man, that rust cleaning is so satisfying
Depending on the gap/material surface, I do the same with MIG. It works really well! Thanks for sharing!
good technique. I used it sometimes with MIG on 3x2 tubing's on trailers.
I think I may be having that same issue with my torch set up. I hope it is as easy as a fix as yours was. Thank you for the possible solution to an ongoing problem I have been experiencing
good video man. im getting into TIg welding at my shop and this helps alot. thanks for posting. you got a new subscriber
Lay wire and walk the cup or pad it then fill. I like the tooth tack technique, could be very useful where positioning is crucial.
That is the one of the beauties of a TIG welder. I'm not sure if the weld is as strong as a close fit, but looks like it should work. Also, lacquer thinner leaves a residue, acetone leaves virtually none.
I would "pad" the heavier side (the corner will take heat better) and build up in one or two passes with filler rod and let cool in between. when gap is the same size and closed up, then weave or whatever your preferred method is, Bridging is ok if necessary but puts a lot of stress on the weld as it cools and makes for more distortion. ALSO bad tacks and porosity may be a chimney effect of non inert gas blowing thru the tube from underneath.
I’ve only tig welded once, and it was at Evander Holyfield’s restaurant that he had in Atlanta. I fused the bar top and edge together. We also did all the handrail, but with a mig.
Pretty Great Justin. You got it. Once ya got it, you got it ! Thanks for showing your knowledge.
Good method. I use another one: i weld all along the long tube once, from side to side of the short tube, and repeat the line again, towards the short tube, until the gap is completely closed. It's faster, it's cleaner, and it looks better cause no tacs.
I usually bridge gaps with stringers. I can span a fair gap with 1 pass. Other than that I'll run a pass on my solid piece and then make the other pass on top or side until I can tie them together. Depending on how I'm doing it. Glad to see your videos popping up in my feed again.
Nice Just learning tig for stainless steel cold trap and came across a gap.. Thanks!!!
Its actually nice to see people giving positive reviews on a video. I like the video, might try this if i come across this issue in the future!
Thanks for the video! Also a great motivational video for doing a better job of fitting up before welding.
Great video, extremely helpful! Thanks for creating/posting.
Been watching your videos for a while mate and got to say your angles of filming and how you explain it is brilliant! For someone like me who has been welding for less than a year now, it’s helpful when someone explain it in a way everyone can understand:) keep up the great work man !!!
Watch all the videos you can. every good welder has a tip or two you may not have heard of and it will help you out later. I have taught people to weld.. but its hard to explain what or why I am doing while welding on a job I wear ear plugs in noisy environment. Earplugs keep slag and sparks from falling into your ear canal when you have your head sideways. but there are great welders and teachers putting out great videos on welding.
Great welding and camera work. Still getting used to arc but seeing you work with TIG makes me want to
get one of these. Thanks.
TIG is a lot of fun, you can get pretty creative with it.
I really like how you take pride in cleaning your material Your awesome 👍👍👍
I actually like that technique. I would generally pulse like a maniac with the foot pedal and pump a ridiculous amount of heat into the joint. I'm going to give that a shot next time. I've also ran strings on one or both edges to build it up to a point where I can just weld it out like an open root joint.
That is a most ingenious method with a great outcome. The vision bloomed during the weld process, but we knew exactly what was going on. I learnt a lot from that! Thank you.
Love tig. So versatile. Can sculpt with it.
Agreed
The initial tacks are good. But your right as far as weaving afterwards. It's super ez. Just point your tungsten at the toe add a drop of filler and feather it to the next toe. Rinse and repeat all the way down the gap. I love tig, and I can get lost in that arc, brushing away! 😁
the last thing you want on a root pass on anything is a weave technique.. youtube can not teach you how to properly weld.. it can infact have you chasing your tail trying
@@justinfryer1347 I've bent tons of tests that were purposely gapped. it's inevitable, you will run into it
TreYay83 the toe is the distance across your weld aka how wide you weld is.. so what your saying is to point your tungsten down and weave? You certainly can’t mean point it back your weld would go black. Forward would point your tungsten into the gap.
I’d like to see that weaved in one pass🤦♂️
So much heat, so much warp, so much burnt stainless, so much wrong.
It wouldn’t happen nicely.
From a red seal welder.
I would tack the corners.
Lay one fill pass on the corner of the square stock. Starting at the wider end.
Let cool. Then with a slight weave hugging the fill pass and whipping to edge of other tube. Using a back fill technique with my filler rod. That would be my preferred method.
On the 4th side I couldn’t back fill I would lay a 2nd fill pass on top of first, and then weave the last pass keeping my fill rod in the gap but closer to the edge of perpendicular tube.
The “ teeth method “ works but would be very prone to contaminates, and inclusions. ( in pipe welding bridge tacks are always cut out due to them being filled with porosity and being hard to burn threw, we usually use plugs when possible ) Also your heat effected zone becomes much larger with all of the bridge tacks. Even multiple stringers with a high rate of travel would come out nice 👍
Remember a colourless stainless weld is the best! All this rainbow shit you see in weld porn is actually not ideal.
@@Beamer866 i meant point your tungsten at the corner of the initial bridge and the work piece. Get a dab of filler in there then drag the arc across the bridge and point the tungsten towards the other corner of the weld and the work piece, another dab of that sweet molten filler and then drag it back across. Come on man
I usually go with a bigger filler rod closer to the size of the gap but the teeth technique is interesting 🤔. I have to try it one day. Thank you again
The way i do that is to run a little bead on the tube. Now the gap is small enough to bridge . Thats how i do it.. It works well for me.
hrlydave83 yup I just run a bead on each side of the gap depending on how big it is then just fill in after.
I call this buttering it up lol 😂
I'm a welding student, I am starting Tig welding on a 2 in pipe Monday, this has helped alot.
Dont do that on pipe! Damn tacks get in the way personally I cut mine out as I get close but I also back feed
DON"T TRY THAT ON PRESSURE PIPE! The in prosess inspector will write BORW with a soap stone right next to the weld. (Burn out, Re-WELD. )
I do tight weave welds to fill most gaps. Thanks for the tip on how to fill the gaps a I can't fill do to the angle and might gun getting in the way.
Justin, you are a very Qualified Welder, TIG Welder, and I’m sure that you are just as good in the other Welding Methods, Types of Welding. I made the Error of Selling my Just 2 Year Old Lincoln 300/300, that I Bought Brand New, that I Later told myself at the Time that I was Moving.... “I don’t want to Pay for any Storage, so I’ll just Buy a New Welder when I get into a House!” Hah!!!!!! I Paid for Storage anyways.... and I never Bought another Welder yet! 🤧🥴 I do have Four Beautiful Grown Kids, and 5 Great Grandchildren! I still Dream, I Dream Big Time!!!!!!! I have a Trailer that I would Love to Customize, without removing anything in the Garage, and so I’d like a TIG Welder to be able to do that.
Keep up the Good Work!!!!!
You Da Man, Man! 🥴👍
Yeah definitely slower using a tig welder on a trailer but you wouldn’t have to worry about throwing sparks all over your garage like a mig.
Great video im just getting back into Tig welding and I do the same thing. I then find myself doing the weave or walking the cup.
Hey dude, I’m a pilot for Victory Air and realized about halfway through this video that you ride with us, thanks for the tip!
#humblebrag
Hey man! I swear I replied to your comment! You flying this coming season?
Having access to both i usually just go for mig when i need to close gaps like this. but yeah i do a very similar thing filling gaps using the tig. Also i do a bigger filler rod. it all depends on the situation at the time. Good video, good advice . . Thanks man
Hasn't anyone heard of stringer beads?
Thanks Justin, I will be practicing some tomorrow myself, thank you for taking the time
Love your cleaning, so important ! GJ m8
I absolutely live watching your videos. You talk as if we are all equall (whixh we are lol) you dont seem to get to excited and ya work through the problem. Im learning quite a bit watching you. Thank you foe sharing. I would love to move down south and get a job working for a race team. Its my altimate goal.
Good job Brother! Great example of bridging a gap weld. I’m like you I won’t use 1/8 on something that thin. I’d rather make multi pass then maybe a weave for final looks. I love CK for what it’s worth
I hold a filler rod in the crack
horizontally and tack it in place on both sides then i weave both pieces together. Its faster than this method but this is definitely an interesting idea that ive never used. Thank you Justin for teaching me something new
I have always used the weave method but I will definitely have to try this, Your a lot better welder then me but I enjoy trying
That was a pretty niffty idea. With luck, I should be learning TIG here soon. I'm excited about it. Liking this channel, getting to pick up some good tips and just over all basics. Thanks!!!!
thanks for sharing. Very interesting the part that underscores the cleanliness of the pìece before welding. I didn't know the acetone use after grinding to remove dirt, because when i looked to the pieces they already looked clean to me.
I appreciate the tips. I will definitely have to try this out.
Just started welding good advice thanks dude
One of the best tig vids Ive seen very clear and articulate bloke. well done
This looks really cool.
I hope this Welding School I plan on going to in NYC opens soon.
Covid 19 shut everything down.
Look forward to learning more thru this channel until it opens.
Great job keeping the camera stable... nice audio too! thank you.
Thanks for the informative vid. For all the mig heads, this is a Info vid. Sometimes your mig machine is down, not available, or maybe all you own is a tig.
Then stick weld it. - Keep the heat on the solid part of the tubing and let the puddle just touch the cut esge of brnch tube. - There is no way what was done would ever pass a code quality weld inspection.,,,,,For the record I'm retired but got I got my CWI 40 years ago
Thanks mate! Good effort.
Texas tig myself. Planning on getting educated in the field of welding soon. And as far as closing gap with stick, basket weave works.
Nice video - clearly explained! Thank you.
Dude thank you for the collet acknowledgement, I had no idea what was wrong with my torch.
Use gas lens if at all possible. Collett style work but you need a smaller cup size to help focus the gas.
Also i agree with you on not mixing brands, just had an issue on a job where we had Miller parts but had a no name torch and when fully seated the Miller parts would not grab the tungsten. Put the same parts in a Miller torch and worked perfectly.
welcome to Tech Tip Tuesdays, Today we're Tig welding Two by Two Square Tubing. Rolls right off the tongue! lol great start to the channel guys!
I just got into tig welding as I am going to school for it and have been watching your videos now and welding for about three months with your gloves and didn’t even know it
Nice! Hope you like them and that you’re enjoying learning tig.
I very rarely even wear Gloves!
Seems legit. Thanks for sharing
I have not had an issue with different brand collets. I probably have about 5 different brands mixed right now. Now perhaps you got a part that was out of spec. Its great that you pointed out wiping down parts and wire. Even those mig wire cleaners help out alot. It really is amazing how they preach clean metal makes a better weld when they sell electrodes that are so oily and greasy
I think the wire is oily / greasy because (A) that's lube for the wire-drawing dies and (B) it keeps the metal from corroding in storage.
Well worth watching. Good way when you must use the piece that you cut.
afandou1966, being a hobbyist and contractually having more time than money*
Was very interesting watching you learn how to video your welding during this video. Also, you've got me suddenly paranoid about my "just burn through the rust/oxide" approach to pre-cleaning the material and filler rod. I think I need to cut through some practice welds and see what rust and oxide actually does to the weld.
Usually the way I do it is to run a pass along the thin edge and thicken it up. Works with TIG or MIG. Then you can run a weave and easily drag the puddle across 1/8" gap, or you can just really push the filler in and run a straight bead. Another trick we used was to cut a piece of 1/8 rod and lay it on the gap, then weave over it with .030 rod. That was on chromoly race car control arms.
The clip around 14:35 or so is a really good shot of filling that gap. Many welding channels don't ever get a shot that good. As for filling the gap, I like to grab the next size up of filler rod. But I work primarily on 16-20 gauge sheet metal, often riddled with rust, lead, old bronze filler etc.
I use Pulsed Tig to bridge a gap it works realy well and it is fast .But good video.
Man I really need to pay more attention to my prep work. Your work pieces have a likeness to a operating room compared to when I tig 😂 so clean!
@@JustVoss yeah I suspect if I were doing structural fab I would pay more attention to it, it's a good habit you've gotten into, though!
Appreciated the video. The correct way is the way that works for you. Looks successful.
I agree
Good video brother, i can mig weld up a half inch gap and get a really clean weld but just starting tig welding wow its different haha
When I’m filling gaps I like to weld in reverse pulling torch backwards and adding the wire from the back of the pool ( bit like welding into a corner )
Appreciate all the comments, sadly I converted my UA-cam channel today and UA-cam deleted all of my replies! Painful part of the channel transfer process but should be good to go from now on.
Perfect.
Watched the video.... and was ready to comment on the sizzle and spadder... I was ready to say hey no gas or wrong gas and as soon as you said different manufacturer parts! Got me thinking!!! I went through 3 different bottles of argon.... same not so nice!!!! Did everything changed from water cooled torch to air cooled and same thing... won't get into names but changed my cup which I loved and went back to ceramic cup and all gooooood! So yeah you are correct !!! Different collet, lense, cup will cause a nightmare!!! Thanks for the vid!!!! Nice to know I'm not the only one or crazy!!!! I mentioned to over 20 welders and I must be doing something wrong..... well I was !!! Just assumed I could take a lense and a collet and a cup from elsewhere and assemble it on one torch !!!!
The "proper" way to do this (from my four years at welding school dont quote me in not a professional), or at least the way I would bridge gaps like this is to use filler rod that has the same width of the gap you are trying to weld and work in the filler metal with tiny half circles as you move along to spread it out nice, worked like a charm and came with some nice uniform welds! but i like the creativity in this video although i feel if i tried it i get way to many keyholes lol, but great vid!
Just wondering if you watch This Old Tony? Some of your content is pretty similar. And that thumbnail is too
Where is your shop? You mentioned air gas and I'm only familiar with the one off the 71. Are you in CA? If so are you hiring? I am in the welding program at Mt.SAC and working for an apprenticeship. Thank you and have a great day. Feel free to contact me (909)260-6998
I think You have the cleanest shop ever .
Awesome! Thank you Justin, the little teeth technique does work when filling gaps.
You bet!
Liked your video it's nice to see someone show you there learning process
Nice clean job. Welding is skill learned and lots of patience to get it right.
Perfect work in an imperfect situation!
Good video thanks for sharing
You did an excellent weave weld style. This is a good method.
Teeth welding isnt your creation but to discover ot by yourself is a very good thing.
You need a better filter for the camera. And actually provides some great info for newbs. Cleanliness is godliness
So overall excellent excellent info. Filler material needs time to cool. Work on explaining cooling pools.
Thanks man, and I think I have the camera stuff more sorted out in my latest video.
That was great tutorial, thanks very much... Seems to me there are not many options when your in that situation.. Great job thanks again
Good video, no rambling on, just a quick explanation and then right to the point.
Thanks, I'm new to tig welding and I'm trying to fill some gaps so this helped but would be much more helpful to see you weld as others have said. Really helpful though. Cheers!
Thanks for watching, newer videos are more clear.
Yeah I use the same method . You can also use a small bit of round Bar to fill the gap both will get you out of a jam but warpage can be a problem.
very informative process; thank you!
i just started tig welding and i couldn't weld mild steel because it was blowing out just like that. thank you for solving my problem
I have never heard of an issue with mix matching torch parts, in fact in almost 20 years I've never known anyone to have an issue. I currently run and Weldcraft torch, Radnor collets, and some Chinese knock off gas lens and cup set that I picked up on Amazon for 10 bucks....welds perfect.
Nice tip. Wouldn't have thought to do that.
Thanks ,I'll keep this in mind
Great demo!
Nice work man. It's really kind of you to share your wisdom. I appreciate you.
Thanks Anthony!
Looks very clean and solid weld to me
Haha cool. This is exactly the method i use when mig welding big gaps, when the material itself is on the thin side. Once those teeth are in place you can easily go over it in a circle pattern. Filled up to 10 mm gaps on a 3 mm thick material no problem.
