生产实践中我们常碰到这样的情况,焊接另件经电镀处理后,在干燥过程中、残存于焊接部位小缝隙孔中的溶液会流出外部,使镀层表面受到污损。如果仔细分析一下这种残存液的成份就会发现,它是在进行第一道处理工序时就进入焊接部位小缝隙孔中的溶液。在其后的处 Production practice, we often encounter such a situation, the other welding parts by electroplating treatment, during the drying process, the remaining small cracks in the weld hole solution will flow out of the outside, so that the surface of the coating was defaced. If you look carefully at the composition of this remnant, you will find that it is the solution that enters the small slot in the weld at the first pass of the process. Behind the place
