Problems solved by technology

Tests have shown that using the chromium-zirconium copper rods obtained by this patented process to make electrode caps will expose the problem of embrittlement during cold extrusion, that is, the problem of fragmentation, so it cannot be produced by cold extrusion at all. However, the electrode cap can only be produced by the lathing process. The lathe processing process has high processing costs and low efficiency; Welding of clad steel sheets for automobiles

Description

technical field [0001] The invention relates to a method for manufacturing an electrode cap used for welding clad steel plates for automobiles, more specifically, an electrode cap for welding clad steel plates for automobiles made of chromium-zirconium copper electrode materials as raw materials The method belongs to the technical field of processing electrode materials for welding. Background technique [0002] Chromium-zirconium-copper electrode materials of commonly used specifications are produced according to the ISO5182-99 standard. The materials selected according to this standard are first smelted in a vacuum furnace or an electric furnace to make a billet of a certain specification, then forged or hot extruded, solution treated, then cold drawn and vacuum annealed (or aerobic annealed), and finally made into Electrode cap products of various specifications required by users. The main mechanical and physical properties of the electrode cap products processed in thi...
