大型焊接件--后车架焊接失效及控制

装载机大型焊接件的焊接应力及焊接变形,影响着零件的使用性能。特别是一些承受较大载荷的零部件,其中后车架最为典型。从维修服务方面反馈的信息来看,后车架的失效比较多。除了结构的因素之外,焊接引起的应力、变形及焊接质量对失效的影响因素最关键。

Large Welding Parts-Welding Failure and Control of the Rear Frame

Loader large weldments cond welding deformation of the welding stress affect the use of performance parts. In particular, some parts bear a greater load, of which post-frame is the most typical. From the feedback information of maintenance services. Failure of post-frame is much more. In addition to structural factors, the stress caused by welding. Deformation and failure of welding quality is the most critical fortors.
