摘要
机械冷藏车的大组装和侧墙密封焊对焊缝的密封性能要求高 ,而底架部分则对焊缝内在质量要求高。混合气体保护焊具有较高的焊缝内在和外观质量。通过混合气体配比对焊接质量影响的研究 。
The general assembly of mechanical refrigerator car and seal weld of its sidewall require high sealing performance of welding line,and the bottom frame requires high internal quality of welding line Mixed gas protective weld can obtain quite good internal and external quality of welding line In this article,the affect of proportion of components of mixed gas on welding quality is researched,and the reasonable proportion and welding technology is put forward
