Thanks for the return. Yes, we trail and back gas, and would like to here if your welds with Er100 (I believe that is what you said) will have the same/similar mechanicals as the parent metal. Our choice is mandated by the government boys and unless I can offer good reason to change it, my request will be denied. The fireworks I refered to is from the tube filler that we have, Vacume melted material has nevere caused any problems in the past. We have hesitated to use it due to cost and long deliverys. The joint is a butt joint single "u" groove configuration. Preheat (700 Deg. F) is used to reduce cracking followed imeadiatly by an anneal. Any hints/ your method would be appreciated. If you like phone calls My toll free number is 888-808-9353
Thanks again Jerry Cotter
