摘要
对U75V合金钢轨交流闪光焊焊接质量影响较大的13个焊接工艺参数,采用正交设计的方法设计了焊接工艺试验,根据正交试验结果分析了主要工艺参数与焊接质量之间的关系.得出了U75V合金钢轨的最佳焊接工艺和影响焊接质量的主要因素,其中送进速度是最重要的影响因素.优化的焊接工艺通过了钢轨焊接的落锤试验,并已应用于钢轨的焊接生产.
Welding procedure tests were arranged with orthogonal design on 13 important parameters to optimize the welding parameters for welding of U75V rails. The factors affecting the welding quality were analyzed according to the results of the welding procedure tests. Among the 13 parameters, feeding speed is the most important. The optimized welding procedure was obtained and has been successfully applied in production.
