摘　　要：采用焊条电弧焊对ZG35CrMo(调质)进行焊接,焊接性能往往不尽人意,因此有必要对ZG35CrMo在调质状态下的CO2气体保护焊进行试验研究。在简要分析ZG35CrMo钢在调质状态下的焊接性能之后,进行了其CO2气体保护焊的焊接试验。试验结果表明,在严格控制焊接热输入、预热和焊后热处理等参数的情况下,选取合适的焊材,能够保证ZG35CrMo在调质状态下焊接的接头力学性能,并给出了具体的焊接工艺。A test study was conducted on CO2 protection welding for ZG35CrMo steel quenched and tempered, in view of poor weldability exhibited in electric arc welding of ZG35CrMo. A brief analysis is given of the welding performance of ZG35CrMo Steel. The results of CO2 protection welding test show that mechanical properties of welded joints are guaranteed with rigid control of parameters of welding heat input, preheat and heat processing, and right welding material. A specific welding process is also given.
