welding thin tubing with internal threads
I have a project,,, where I am welding a mild steel threaded tube to
a .106 thick mild steel tab that is about 1" long. The tubing is 3/8 OD, with .280 ID, threaded 5/16 x 24. The weld goes lengthwise on the tube, and is the full 1" long. I am having trouble not distorting the threads in the tube when welding. I am tig welding with a 1/16 or 3/32 electrode (sorry, will check in the morning for sure... it is the thinnest I have) and 1/16 (also the thinnest I have)mild steel filler. I am not a weldor, but have had some tig and mig formal training. Machine has a pedal that varies the welding amps, and I am not hitting it really hard at all... I tried putting a bolt inside the tubing while welding, but that just fused the bolt to the tube, oops. Anyone give me some constructive, positive help please? |
