When i bought my 1994 Dakota, i noticed that the fan shroud was missing. They had rigged an overflow bottle on the core support. When i tried to put a new fan shroud on it hit the fan, so after some searching, i found that the frame was bent right behind where the core support mounts to the frame, which in turn pushed the radiator and core support back a bit. The reason i didn't notice it at first was because they had also made sure to realign the headlights, as well as replace the grill, so all i noticed was that the bumper was bent in. The bend is in front of where the front suspension
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
