I really liked "man cub's" explanations about how to get a good root pass, and hot pass, and especially how to get around obstructions as you weld, very informative.
Excellent job explaining everything. I can tell you are camera shy but I understood everything pretty well especially when you are explaining while welding especially on that tig root
I have a question about arc length in dc tig. Obviously you want as short of an arc length as possible for the best penetration but if you had to make a fairly wide bead as either a cap or just that the specs require it to cover more of the steel can you draw a longer arc length with higher amps to widen out your cone or are you better off just making multiple passes or doing some kind of weave or walk the cup?
Its crazy how easy you make that tig root pass look... weldon, but i was wondering why you start out with 3/32's 7018's rather than just go right to 1/8 rods, would seem like higher deposition rate, only need to grab one type of rod therfore less time and potentially less cost for the filler metal and I would think better you might get better fusion and less chance of slag inclusions or porosity given the higher heat?
@@FishFind3000 exactly I asked the same thing and they said his working at the collage and still taking time off I personally think he is never coming back and they just don't want to say it as they would just be one of the thousands of other welding video channels without him
Tip #1 If you even think you dip your tungsten stop right away and grind a little bit. Tip#2 If you keep welding with a dirty tungsten you are putting some particles of tungsten in the puddle.You wont even see it your eye. When they x-ray your pipe it will have tons of white tungsten particles when looking at the x-ray. Tip#3 Bring you tungsten back into your cup where you cant touch your puddle Tip#4 If your welding carbon steel get all the mill scale off where your are welding. Tip#5 On carbon still pipe get the glass (silica) deposits off with a file or whatever you have on hand. After you make each pass. Tip#6 Do a slight pause on your toes with tig to burn in good. That were you will get lack of fusion. Hope this help buddy
Great job ManCub, easy to follow commentary, like the Tig hot pass ,,,, always seems a shame to hide the pretty welds :) keep up the great videos team.
Maybe it's the camera microphone but it sounded like you were running 7018 in straight polarity. Also if you have a low spot on the root and you just turn up your amperage and run it over, you will just end up making it worse.
Great video! One small tweak. It's easy to get nervous and start talking too fast. It would be great if you could pause, take a deep breath or two, and talk about 10% slower.
A quick stringer with 3/32 lo-hi on the top of the bevel before the cap will make the last cap pass wet in alot better and you won't have to stack as much iron to get that last pass above the bevel. Anyways great job brother that's just a little trick I employ on any horizontal weld.
Just curious but that sounds like an unusual procedure? Any reason they do a 7018 fill cap instead of FCAW? Or is just so they qualify two procedures for field work if guys need to stick weld sockets etc?
My bad, it could be to do with base material too because we get some high alloy carbon pipe that can only be tig root and stick fill and cap to meet the required tensile strengths etc.
Its pipeline procedures I dont know why it's that test but after pass the 6g they want 12 on12 saddle. For shop job....only flux is on there skids...and there 100% x ray also they build launchers for pigs ....so I had a lil bit undercut on the capp
Cool as, I’m in Australia. Mainly done shop spooling and site work for power stations and oil and gas. I’ve busted tests so best of luck on the next one! You learn from your F-ups ay!
@@chrisplayz253 they said this fall he would be back and that he is working at the collage and still taking time off but I will believe it when I see it his humor made the videos worth watch just as much as the knowledge he has
97 amps? If it works it works👍 personally i like to go in bit hotter than that on a root, around 115-120 on 6" s80. We only use 2.4mm rod so a bit different, but thumbs up!
As a welding and metal fabrication student that's hungry for knowledge and a new AWS Member what AWS literature should I get and read? Thanks for the help
It’s common to do tig for the root on pipe because it’s a very clean weld. You could use stick but stick has a slag coating when it cools that has to be removed. On a sealed pipe you would have no easy way to clean it. The fill passes are stick because if you did tig all the way out it would take forever because it has a low deposit rate.
Hi man cub I have a question for you or anyone that can be of any assistance I'm trying to figure out why I keep getting undercut when I do my last bead on my cap im running 1/8 7018 Excalibur rod @ 110 amps on a lincoln invertec the arc is set on soft also same settings for the bottom and middle pass on the cap no problems just on the top one same pipe as this video ,I've tried pausing longer on the top when I oscillate the rod in a zigzag motion to allow it to fill in but still get undercut also I allowed the pipe to cool down before I started the pass any guidance you can provide would be highly appreciated thank you for your time

You killing it. FLEXING. That's what I'm talking about.
Thank you and thank you for watching weld.com
Maaaan this guy is a great teacher my hats off to you my man
Thank you
Agreed! Skilled too. Also my hats off to the camera man... those arc shots were fucking nice.
Mr Mike I really appreciate and I will let camera guy know. Camera guy works hard
this guy describes tests really good i watched him a lot in trade school
Little trick I learned in school. Lift that post arm up, flip the coupon upside down. You can walk all the way around it then
Mike Ford most tests you can’t break out of position, but if it’s just practice I wouldn’t see an issue
As a welder BOILERMAKER iv always had a voc school n that was my shop. N with all the codes n procedure s I can practice for test day .
PERFECT WELD!!!! I HAVE PASS 100 of these WELD keep up the GRATE WORK!!!!!
YOU DOING Everything right keep up the GRATE WORK !!!!! Your root temp is perfect 97 amps H9T pass temp 110 was right
Way to go Cub! Keep on keepin on and don't let QC or CG get in your head. Nice tutorial with some valuable "Cubtips."
It was good but not bob Moffatt good 👍

great job , Mr bob would be proud of you , well done
Bunch of negative comments. I found the video very helpful. Thanks Mancub
Great video man cub!!!👍
Thanks you Jim Miller
Looks good to me man. I learn so much from these videos. Just started combo today
I keep coming back to this video. Amazing video in regards to the puddle.
Good video. Thanks. Glad to see you doing welding lessons on your own. I think you have a lot to share.
That’s looks awesome!! Great job!!
Shaun thanks
Shaun thanks
Hell of a difficult weld ont that first pass. Awesome.
Proud of you, man. Well done!!!
Thanks bro
Great info especially on the pausing while tigging. Thx!
You packed a lot of good tips in there--thanks! Very good camera work.
Thank you. I love passing knowledge on to other people.
You've definitely picked up some skills 💪
Thanks jc
You've come a long way young jedi
Awesome video, thx man for very useful tips. Also great respect to an old master.
WE WANT BOB! WE WANT BOB! WE WANT BOB! WE WANT BOB! WE WANT BOB!
Thank you for your video!!! I love that trick about the wire hanging in there!!!👍👍
Authentic instruction. Is it OK to stop the TIG weld to reposition the body and restrike the arc? At 12:00 was the arc erratic? Why?
I think you're referring to the camera shake.
U did a great job explaining man!!!
Great video and camera work
Exactly what I needed to see today. Well done
Nice job man cub
Nice work there. Keep on laying it down. Jim Tree
Nice job man cub !!!
❤️❤️
Marvelous work
I would have a hard time putting a cap over that beautiful hot pass! =D

Obviously you want as short of an arc length as possible for the best penetration but if you had to make a fairly wide bead as either a cap or just that the specs require it to cover more of the steel can you draw a longer arc length with higher amps to widen out your cone or are you better off just making multiple passes or doing some kind of weave or walk the cup?
Ben Miller sharpening your tungsten to about 15 degrees like a needle and you should get a wide, low voltage arc column.
Well done man cub !
I like you young guns, but I miss the old man. Where’s Bob? I hope he is doing well.
He's still teaching at cowley college, still kicking ass and taking names
Gotta have Bob back once in a while!
Hes crankey
Guy's a legend too me his videos helped a shit ton when i was in trade school

Plz what are the tips on how to pass an xray weld test. Defects to avoid and things to do. Just tips thanks
Tip #1 If you even think you dip your tungsten stop right away and grind a little bit.
Tip#2 If you keep welding with a dirty tungsten you are putting some particles of tungsten in the puddle.You wont even see it your eye. When they x-ray your pipe it will have tons of white tungsten particles when looking at the x-ray.

Richard Solomon thank you
This is the most helpful Filthy Frank has ever been
Learned alot with this video appreciate all the info
Nice one "MC"
As it is said on IG, "no longer a Man-Cub" and one can add he is TIGer, now!
🤣

Nice one. Keep it up
I start Tig Monday, I’m so excited about it. I already know it’s going to be challenging
It's the most fun but tedious
It's fun. My favorite of all processes
Great video. Good information and good camera quality. Thanks for sharing with us. Dan
Thumbs up. You're doing well.
What kind of grinder did you use to take off the inside corrosion paint??
I pre-ordered the Lightning 275 last week.... So far, what do you guys think about it all around??
Hell of a machine. You will be happy with it.
Did I hear that correct...1/8" 7018 @ 100amps? Little cold 🥶
I cant fucking wait to get a job and start working and learning as much as I can
this is awesome love this
Good job very helpful but where the heck is Bob at
Thanks
gone
Nice
I don't understand,mabye because I am newbie. Why you do not purge back side with argon? I saw some guys purge pipes.
Great video!
One small tweak. It's easy to get nervous and start talking too fast. It would be great if you could pause, take a deep breath or two, and talk about 10% slower.
Thank you so much for explaining! Well done 👍🏾
Could you guys do some 6010 three pass fillet welds in all the fillet weld positions 1f-4f because I could really use some help with it
Does the root get any light grinding before the hot pass ?
Man cub merch! Man cub merch! Man cub merch!!!!
Has anyone told mancub he's a boss?

What kind of wheel is that on the dremel? At 00:21
Very nice
Other than a waste of money, why is stainless the only one that gets purged with Argon? Why not do the same thing with mild steel?
when that old grand master coming back ?

Ied say figure out what you want to do and find every corner to cut
What size cup you're using for root and hot pass?
Just like eating ice cream....😉
Non-welder question: Is it common to do a combination of two types of welding? Why use TIG on the root pass?
It’s common to do tig for the root on pipe because it’s a very clean weld. You could use stick but stick has a slag coating when it cools that has to be removed. On a sealed pipe you would have no easy way to clean it. The fill passes are stick because if you did tig all the way out it would take forever because it has a low deposit rate.

Wow omg amazing!
Trial and error is easy to avoid if you study welding 😉
Why don't you get the first bass(6G)
What exact Everlast is that??
Awesome

What size cup is that ?
I never hot pass with 1/8 I like to wire wheel that root then paint my hot pass on with a 3/32 rod
If you watched it and think this one looks tough, you ain't ready, boy! You gonna shit your pants when you see the jobs you'll be given!
What size tungsten?
