挖掘机动臂焊接变形及其控制方法探析

Research on the welding deformation in excavator boom's production and the controlling methods

介绍了实际生产中挖掘机动臂焊接变形的种类和危害,通过对动臂焊接变形产生原因的分析,介绍了在生产中综合考虑制定合理的焊接工艺、设计实用的工装模具和充分利用反变形法等有效措施来控制焊接变形的方法,在生产实践中不仅有利于保证动臂的焊接质量,还可以显著地提高生产效率。

Introduced thekinds and harmful of welding deformation in excavator boom＇ s production. Then introduced how to make rational welding process, design useful fixture and deformation in reverse methods which always used in manufacture to control welding deformation availability. Through abundance produce practice, not only can find these methods to control welding deforma- tion of excavator boom availability,but also can enhance the produce efficiency conspicuously.
