I posted a topic at the welding and metal fabrication forum on one way to restore a bore in a stamped steel piece: "Weld Mold 26-C 'How-to' Oxy-Acetylene Repair: Restoring a Stretched Bore in Stamped Steel". In that 'how-to', I mention heat treated metals and also refer forum members to one of the magazine's slideshow video presentations. The slideshow discusses a major concern when welding, brazing or silver brazing (hard silver soldering) near heat treated parts. Many automotive parts, especially wear points like gear teeth, shafts, splines, thrust washers and running surfaces, have be
Metallurgy and heat treating are a vital part of metal fusing. It is not simply a good bead or welding technique that assures a safe, quality weld. Filler material must match the base metal. Heat treatment is often involved after the machining and finish of alloy metals. Chemistry is a critical part of metal selection and the choice of welding filler materials used with specific alloys. Metallurgy and heat treatment are not abstract processes for manufacturing only. I have repaired obsolete gears with chipped teeth, where the 8620 base metal has been case hardened to 0.035" or so depth at
