I'm hoping someone might share some tricks for welding sanitary 304 SS Tri-clamp-style short-weld ferrules to tubing without warping the ferrule. I've tried tightly clamping the ferrule to another or a cap to hold it, but the clamp gets in the way and it will still warp if it gets hot enough. I've tried making additional tack welds for the fit-up, but that doesn't seem to impact the flanged edge of the ferrule itself. Years ago, an experienced sanitary welder told me short weld ferrules were tough, but I don't remember what he said about how to avoid the problems. My guess is it all comes down to getting the weld accomplished with as little heat as possible. Until my technique improves or I can get access to a machine with more rapid pulsing, I'm not sure what else to do.
