机译:Q: Sometimes brazed parts are damaged or even destroyed during heating due to melting of a base metal in contact with materials of a fixture or with another base metal when dissimilar metals are brazed. Recent cases (Figs. 1 and 2) show melting of carbon steel in contact with a graphite tray (Fig. 1) and melting of a titanium part contacted with the nickel foil (Fig. 2). What is the nature of contact melting and how can it be prevented to save parts to be brazed and cut production costs?
机译:What is the appropriate minimum ferrite content for Type 347 stainless steel and weld metal? We weld by autogenous gas tungsten arc welding, so the base metal ferrite content matters a great deal. We are having difficulty locating a 347 base metal that complies with API RP 582, Welding Guidelines for the Chemical, Oil, and Gas Industries. We have been receiving heats that barely comply with a 3 Ferrite Number (FN) minimum. Our most recent heat does not comply
