箱式梁的焊接变形是较难控制的,千秋煤矿机修厂在工作实践中探索出了防止箱式梁在手工电弧焊焊接过程中变形的焊接工艺。通过对箱式梁焊接变形的原因、类型、控制、矫正等进行简单阐述,结合工作实际设计出了防止箱式梁焊接变形的焊接工艺,并在车间推广实施,达到良好效果。 Box girder welding deformation is more difficult to control, Qian Qiu coal mills in the practice of practice to explore the box beam in the manual arc welding process of deformation of the welding process. Through the analysis of the reason, type, control and correction of box girder welding deformation and so on, the welding process to prevent the box girder from welding deformation is designed according to the actual work, which is promoted and implemented in the workshop to achieve good results.
