Some p91 field weld OD prep for phaser ray this is a power house main steam line. The system runs at 1950 degrees at 2400 psi. The weld shot good time for drinks!

Green time- I have a network of people with many more years of knowledge then my self that I can call. a machine shop I do some side work for had a book of aluminum alloy and info on them ( as applies to machining) . I just wanted why there's not something like that for welding . Also like the tangi...

Anyone know or seen a alloy reference guide? where you can look up an alloy find out what wire to use and other info such as per heat temp or weldability .

thank you sir.A blind squirrel finds a nut every once in a while !

Tig/stick 14" pipe tie-ins took a picture just off the bottom .

Hi, I'm on a project at work and was wondering if anyone could give me some advice. We are building a pressure vessel out of 5/8inch, 516-70 plate and need to weld it all with metal core wire. My question is regarding the welding of the heads to the body. Both head and body have a 37.5 degree bevel...

I own a mp210 iv ran this machine threw it's paces. I bought my machine to work for a week and build a steam header with it on 110v mainly tig welding with it. Hours and hours on 110v tig and stick welding I love this welder! All welder were x-rayed as per code.

There has been a discussion about aluminum shavings on the table causing arc marks on the workpiece. There are...

Thanks guys I'm glad to be here!

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

This weld is a code or stamped weld it will be QCed under 31.12 boiler code ( no under cut ...
