A Iron-Chromium b Iron-Chromium-Nickel c Iron-. - Reconditioning of exhaust valve spindle - Plasma transfer ARC PTA welding - Repairing of turbo-charger casings and AE cylinder heads - Fusion and cast iron welding - Oilfield servicing - General machining. The process for the fusion welding of spheroidal-graphite cast-iron castings comprises the following steps.
Engines and mechanical parts.
Slow cooling is recommended after welding. The welding technique should be to direct the arc against the deposited metal or puddle to avoid penetration and mixing the base metal with the weld metal. Through the use of welding practices and consumables described in the Guide for Welding Castings and other references used in this Section Ductile Iron castings have been joined successfully to other Ductile Iron castings and to steel in the fabrication of automotive and other engineering components. Improving the weldability of SG Ni-Resist D-2 iron.
