A pressure vessel repair today . Cut ,prep, fit, weld . Nothing glamorous but it's a paycheck

Maybe not glamorous to you but involves serious skill and experience. Good job!
Now you have to elaborate on process and procedure used please.

the welding process is smaw (stick) we use 7018 for the vessel. This weld is a code or stamped weld it will be QCed under 31.12 boiler code ( no under cut or any indication while they pt it) and stamped with ASME stamp .after that we will hydro the tank to 300 psi twice the stamped pressure. This vessel is apart of a water treatment plant for a power house. Definitely not glamorous but I love what I do and being challenged every day and pushed to weld at a very high standard has put me and a very fortunate situation!

Had to repair some dirty old stainless can't always be weldporn with new material at a bench. There is something satisfying about welding all curled up like a pretzel.

I couldn't get to the backside of this weld really good to clean a couple spots gave me issues.

We all know that's true, good work as always Rick

Well on this Friday we get back on our tig rigs 4" sch 40 70s6 ( not my favorite wire for carbon) welding under code 31.3

Nice work, I prefer 70s2 if allowed personally.

Thank you! 70s6 always seems to run trashy for me, I also prefer 70s2 less cleaning if anything.

Making a new turbo back system for my MK4 TDI, 3" dp, 3" straight system....and I know you guys are shocked it's stainless and sanitary welded.

Clean!

I'm going to have to work on my pipe welding, I want one for my TDI, but can't stand the thought of paying what the commercial offerings are asking!

Yeah there was no way I was going to pay near $300 for a DP, I actually don't have a ton of money in everything front to back. I bought some fittings from Andron Stainless, if I knew how to pie cut or.could easily cut those at home I would have saved even more. It's been fun...have to mock it up today to get the angle of the DP right and make the middle section....then just weld it and add hangers. I used a 2"-3" reducer at the flange so I'd have bolt clearance, and a Vibrant Flex joint.

Prototype done for the 10th Gen Civic Intercooler and Charge Pipe setup.

First time welding cast with 5356, can't say I'm really a fan. I don't know if I'll get to weld anymore of these, but we'll see if I can weld one with 5356, 4043, and 4943 back to back to back (batch work is nice for testing some times) with identical settings and see who can tell what!

Ok this one was not today but I wanted to share it. This was at a nuclear plant on the turbine deck (so no radiation that's why I had my phone)

Awesome work Sam...

Welded this today.

This will have a big tower mounted on top like the last one I built. They wanted it to hinge on 2 small brackets, but there's no way it old hold plus the brackets were way off so I built a doubler and gussets.

This will be really cool when it's done I'll show you guys later hopefully.

Keep forgetting to post my experiences with SolarFlux. This stuff is gold if backpurging stainless isn't reasonable or practical. I use it with ISO alcohol, works GREAT!!!

Did you butter up the two halves before or after you tacked them up?

Woo hoo !! Just found out the paper work went through and I get to take my weld test for my R stamp next week.

Awesome! Good luck with the test Josh!

After, I tried to keep the tacks shallow. I didn't clean it all up since it's just an exhaust pipe but I wiped off an area with acetone and it's nice and shiny metal underneath.

Cool! I was wondering if it would interfere with the weld process if it was worked down into a crack. I'm envisioning that you might be able to coat the two sides before you tack up. If there was no way to get at the joint after fit up.

Another flex from the other day
