Am looking for equipment to stud weld Accoustic Emission wave guides to low alloy pipe. The wave guides are 304 stainless round stock, .250" in diameter and 12" long. The other end of the wave guide has a 2" x 2" clamping device welded to it. I'm guessing the challenge will be to find equipment which will handle stud material this size. Anyone have any experierce or helpful advice with same or similar material.

Thanx in advance,
Dave
