Excavator bucket rod upper end cracking reason analysis and improvement,1.Cracking phenomenon of a model of excavator factory work 3000h or so, one after another, the upper end of the bucket rod cracking phenomenon, cracking part is located in the top of the bucket rod reinforcing plate and the bucket rod cylinder piston rod support plate articulation overlap weld at the vertical plate.

Welding deformation control methods are diverse and can be applied flexibly in different situations. Due to the complexity of the welding process and the ever-changing morphology of steel structures, the search for efficient control methods has always been the focus of research in the field of structural steel welding.
