I'll tell you something. The place I worked at had our own weld shop. The guys in there could weld, braze, solder or any or that type of work. I could probably name a dozen guys, retired, I worked with who could braze those. I know the guy who welded up a piece for my lawn mower was good enough to braze or solder those type of barrels. They had to learn to do all types of work like that to repair our machinery.
