Hello there, I'm Eric. I am working on a project right now where i have 22ga stainless steel (.0299) and I will be spot welding it to .020 stainless steel. I'm fairly sure that I should use TIG. I have a few questions hopefully no one minds answering. Thanks in advance.What type of welding should I use?If TIG what parameters?Amps?Filler wire?Flow of argon gas?Thanks,Eric
Reply:theres a thread right now under mig stick tig ox welding called "tig brazing."..something to consider on the light stuff...
Reply:Are you going to be melting through the top piece into the bottom, or are you welding into a hole?Does it matter if the back side has some burn through? DCEN.040 or 1/16 2% Thoriated tungsten25 amps maxYou didnt say what the base material is, but 304/308/309/316 would probably work. .030 or .035 mig wire will work well, if you dont have cut lengths.15-20 argonHave we all gone mad?
Reply:1-Some pics or sketches of the joint detail and 'project' would really help and 'project'.2-Do the sheets have any bent edges, flanges, etc.??3-Reason for these idiot questions is simple--distortion.4-You say 'spot weld'. Do you mean plug welding via TIG or resistance welding, which istruly 'spot welding'.5-Is exterior and interior finish/appearance a concern?Blackbird
Reply:I dont have any pictures. but i want to do T and butt joints. i do not want it to penetrate through the metal only penetrate in the crack for strength. im not farmiliar with the terminology but half inch spot welds along butt and t joints. the finish is not a concern. |
