摘要
在焊轨生产中,为了稳定焊接质量,从焊接设备角度分析如何保证焊接工艺稳定状态,对于进一步减少或消除焊接缺陷十分重要。以K1000型固定式闪光焊机的电极与钢轨底板接触的契合程度,通过调整电极与钢轨接触面的契合程度,达到标准焊接状态,研究了由此所引发的轨底脚灰斑、轨脚过烧、三角区细小灰斑和未焊合等缺陷数量分布特征,以及对焊接质量的危害规律。结果表明:电极与钢轨的接触状态不良,会导致工艺参数的调整难以获得稳定质量的预期效果,在很大程度上会影响钢轨接头落锤稳定性,应在生产中给予重视。
In order to maintain the quality of welded joint during the manufacture, analyzing how to keep the welding procedure steady from the perspective of the equipment is so important to eliminate the welded defects.This article elaborates the influence of K1000 stationary bash-buu welded joint quality based the degree of the electrode accord with the rail surface from below grade up to the standard.The flat spot in the bottom of the joint,overburn and lack of bond will be easily raised and each has its own rule of harm. The test resuhs inticate that it is difficult to achieve the process parameter test expected effect if the degree of the electrode accord with the rail surface in a bad situation, and the stability of drop-weighttest of welded ,joint will be greatly affected. More attention should be paid on this factor durin manufacturing.
