I have a call to repair a leak in the weld around one of the pipes/ nozzles on a large industrial transformer. I have an asme R stamp as well as AWS certs and have made countless welds like this before. Prob is the procedure calls for oil to stay in the transformer at a min of 4 inches above the leak point. This we have not dealt with before. Plan is to pean the leak shut, clean it and weld it . I have been pondering using a tIg torch to close the leak completely prior to re welding the area with 7014(7014 is what the procedure calls for) I am hoping someone has some experience with this that might have some 2 cents to help us out. Thanks in advance!!
