Simulation and Optimization of Spot Welding Process Parameters for Iron Core Assembly of Micro Electromagnetic Relay

针对某型号微型电磁继电器铁芯组在实际焊接生产过程存在点焊飞溅大的问题,运用有限元点焊仿真技术对铁芯组点焊过程进行数值模拟,最终通过优化焊接工艺参数的方法,实现了铁芯组无飞溅点焊,极大地减少了因存在金属飞溅多余物而导致产品失效的质量隐患,提升了该微型电磁继电器的质量及可靠性。

In this paper,aiming at the problem of severely spot welding spatter in the actual production process of a type of micro electromagnetic relay iron core assembly,the spot welding process of iron core assembly is simulated by using the finite element simulation of spot welding technology.Finally,by optimizing the welding parameters,the non spatter spot welding of iron core assembly is realized,which greatly reduces the quality hidden danger of product failure caused by splash metal remains.In general,the quality and stability of micro electromagnetic relays are enhanced.
