Im tig welding alot at work, but im starting to feel sore in my wrists from walking the cup all day. How do you guys avoid this? Should I buy glucosamine and chondroitin? Does this happen to any body else?

Hey im tig welding carbon and at the end when I go to tail out im getting porosity. This has never happened to me before and I cant figure out the cause. Help!

Joint configuration? Its a socket weld. Do you put 2 passes of 1/8 or 2 passes of 1/8 and a 3/32?

Im about to start tig welding two inch sockets at work. Er70s2 wire. What kind of set up do you guys run to make sure theres no concavity and im filling the socket up properly. A qc will inspect them with a gage. Schedule 80 pipe.

ive been running the wrong filler metal. Ive been running 309 when I should be running 308. : /

With this one I ran the root with 3/32 gap and rod,heat at 60. Cap was 55 with 3/32 rod. I still burned through in some spots though. I tried the 1/8 rod at 75 like you said but burned through big time. After the root I let it cool to the touch and after each stringer I let it cool to the touch. But...

Ok that sounds good. Yea its very thin so fusion would make sense. Do you recommend using a 3/32 filler wire when fusing it or doing it autogenously? Also what heat do you run your cap at? Sometimes I have problems reconsuming the root on my cap. Do you run your cap slow and cold or hot and fast?

How are you putting in the root without a gap and your heat at 55. Are you putting alot of pressure on the wire? Seems like you wouldnt get enough penetration.

Im tig welding 2" schedule 10 stainless steel pipe. I was wondering what you guys would recommend running this at. Tungsten size, gap size, filler wire size, heat. Ive seen some use laywire techniques and some use dip techniques. What would you recommend? Thanks for your time.

Ok I get what your saying. Ill try that die grinder trick tomorrow and let you know how it goes. Thank you for the help.

After im done welding the root ill look inside the pipe. The root on the inside will look good except for a small circle usually on a tie in. Also after ive laid down my hot pass. Ill look inside the pipe and see the same blister looking circles on the root. I didnt get what u were saying on that la...

I turned the flow up and this problem was fixed. Thanks!

Sometimes when tig welding stainless I get these small circles in the middle of the root from refloating the metal. Any suggestions on how to stop this problem?

Thanks, I'll try and turn up the argon. I tried turning it down a bit recently because I was afraid of pulling in oxygen, however I may have turned it down too much. Here is a picture of what I'm working on. This is a 1/8 rod on the cap which has never given me problems but when i tried 3/32 I kept ...

Sometimes when tig welding my caps the filler metal will ball up. Why does it do this? Im using 3/32 309 stainless wire.

Im welding 2inch schedule 80 carbon steel, 1/8 309 stainless filler metal, argon purge and shielding gas, tight 1/8 gap for root. If you have any tips, tricks, or set up info on this process please respond. THANKS!
