At present, the research on stainless steel spot welding mainly includes argon arc welding, laser beam, electron beam, and friction stir spot welding, but the above-mentioned spot welding methods consume a lot of energy, have low production efficiency, and high equipment, maintenance and operation costs. Resistance spot welding stainless steel is an excellent choice, but the nugget formed after resistance welding stainless steel welding undergoes a phase change, which leads to corrosion during use, resulting in failure of the welded joint, so it is urgent to develop a method that can improve the resistance of stainless steel resistance spot welding. Corrosion-resistant method.
经对现有技术的文献检索发现，专利200510072511.5使用中间薄片圆环焊接不锈钢，但薄圆片的导电能力不是太强，同时薄圆片的材料为不锈钢同质材料，在电阻点焊高电流效果下容易形成铁素体，从而耐蚀性下降。专利201110028353.9改变电极的尺寸提高焊接效果，但增加了设备消耗。所以目前急需开发一种不改变现有设备条件下能够提高不锈钢电阻点焊强度及耐腐蚀性的方法。After searching the literature of the prior art, it is found that the patent 200510072511.5 uses the middle sheet ring to weld stainless steel, but the conductivity of the thin disk is not too strong, and the material of the thin disk is stainless steel homogeneous material, which has the effect of high current in resistance spot welding.
