托圈耳轴的补焊工艺

Technology of Repair Welding for Ring Trunning

重点分析耳轴材质和焊接材料、参数的选取及焊接工艺参数的控制,保证补焊没有焊接内部缺陷和外部裂纹,保证设备加工后的强度、耐磨、耐热及其它的使用性能。

The paper analyses the selection method of trunnion material quality,the welding material,the parameter and the welding process parameter's control,guaranteed that the patching has not the inherent drawback and the exterior crack,and guaranteed that the equipment has processing intensity,wear-resisting,heat-resisting and other operational performance after processed.
