I haven't welded stainless TIG or TIG in almost a decade. Hoping this will kick start some of the tricks I've forgotten about. Going in to test tomorrow.
Hey mate. I have been a pressure pipe welder for 30 odd years. In Australia. Working on things ,ranging from gas platforms at sea,to refineries ,and construction. I have never been allowed,to carry out a tig weld in the VERTICALLY DOWN POSITION. ON ANY MATERIAL. In fact. ,if that is what a welder is seen to be doing on pressure pipe, THEY GET THE SACK
I am welding uphill. Camera captured filming upside down, most likely due to its placement and or help the viewer learn. It *appears* to be welding downhill, but the next shot of my body, is welding uphill
I thought the exact same thing, but he's on a rotator and it's the angle of the camera That was my first thought. Since when do we weld tig vertical down lol
You always tape off the open root of a weld that needs to be purged (SS, duplex, inconel, etc). Leave a bit open to start the weld, and progress from there. Argon is heavier than air, so naturally when you roll weld pipe, the open part is on top. That allows the air to be purged out and the argon stays inside to keep the inside of the joint an inert environment. Duplex needs to be inert on the inside of the joint while being welded or it will get ruined.
stuck on some like schedule 10 i think the real thin stuff for stainless at school. shit whoops my ass. hope one day i can get to the big boy stuff like youre on
Make sure your tungsten is sharp af, short stick out, 3/32 or 1/8th” gap. Knife edge the bevel get it really sharp. Whatever gap you use, use that size rod. Run about 70-75 amps, walk the cup real tight and watch the key hole open up then dab some wire in there, watch it slightly drip in there and then add wire again when it opens up. Can’t go wrong it’ll go in slick.
That's part of the original root pass that was not touched by the grinding disk., the one side is lower., that speak was completely untouched. If that was a gas pocket., that would be a clear indication that there would be more then, in the weld itself. However, as the welds were 100% xray., severe sour service., ultimately then it is now unlikely a gas pocket

Have you guys ever done sch 10 pipes could really use some tips on those
Hello, what is the difference between stainless steel and duplex in terms of technique?
Travis is one of the best I've seen, especially I like the video TIG welding by looking through the gap, AWESOME man.
Well done Travis another great video

Travis is the man!
I would like to see the inside root and the finished cap
Travis is amazing and skilled. To bad he couldn’t take over GRB instead of them closing. We could have learned from yet another master welder.
GRB Closed?
@ few years ago I believe yeah
My gap significantly close when i do my stainless steel root what should I do
Good video. Helmet looks like it would be tunnel vision. I work close to your shop in Nisku.

Travis you number one!!

"Moving from a slight downhill progression to more of a 12 oclock"
That is what he's talking about
It that tape around the weld the bevel? Whats the purpose

How much gaz inside???
Great work sir nice your are awesome
You guys do a lot of duplex over there, Travis?
Why don't you make video of duplex welding in 2g and 5g position please, thank you..
I was always told clip the end of your wire when you stop. For contamination.
I never clipped it and never gotten busted X-rays , you’ll burn it with the heat
Why You didnt show us root?

Do you have send to Guatemala ?
Why you not show in the inside ?
Because we all know it's flawless .
1:33 tack breaks.
Dude pulled TF out of that flange
easy weld in the shop. try weld in the field or in the tight spot scaffold plus humid weather 😂
Ive always purged the same way but guys will argue with ya and put one line in and crank it lol
Would have loved to see it welded in a fixed position instead of rolling it out nice video
Nice❤
9.58. Are you just about to wiggle your way over a gas pore from the previous run?

Great video unfortunately you're difficult to understand either because you're speaking too quickly or too Softly.❤
my ex g pierced her tongue and suddenly she speaks like a retard, its like a having smoke pounds of weed. correct me if im wrong.
.passes out from boredom
dont watch it then
Para aprender 👍👍
Why do you have to bother with the pipe?
The inside didn’t even break down
