挖掘机作为大型工程机械的一种,其在基建工程中起着举足轻重的作用。而挖掘机动臂在焊接时由于热变形及焊接缺陷等原因,容易造成动臂的整体变形和开裂,这对挖掘机的质量是致命性的。为了避免这些问题的出现,合理的焊接工艺、优良的加工设备、正确的焊接方法显得尤为重要。随着新技术的不断涌现,越来越多的焊接技术可以应用到其中,从而降低焊接过程中变形和开裂的发生,节约企业成本支出,实现企业的利益最大化。
Excavators as a large construction machinery, which plays an important role in infrastructure projects. The excavator boom in the welding due to thermal deformation and welding defects and other reasons, likely to cause the overall boom deformation and cracking, which excavator quality is fatal. In order to avoid these problems, a reasonable welding process, excellent processing equipment, the right welding method is particularly important. With the continuous emergence of new technologies, more and more welding technology can be applied to them, thereby reducing the occurrence of deformation and cracking during welding, saving business costs and maximizing the benefits for the enterprise.
