Linear dimension establishes weld integrityStudy finds that when automatic in-place tube-welding head is used to butt-weld two stainless-steel tubes together, welding process can be made so reliable that when weld exceeds a certain minimum dimension, penetration of weld can be assumed to be complete. Detailed procedure for tube welding considers effects of arc gap, shielding gas, welding speed, and other parameters related to weld reliability.
