Question: I was torch brazing a large-diameter copper tube into a copper fitting and built up a nice fillet on the top of the joint at my customer’s request.

The same torch can be used for each process (brazing, braze welding and welding), but the torch-handling techniques involved – and the training – are VERY different.
