摘　　要：从轧辊局部堆焊修复入手,介绍了Cr3型冷轧工作辊耐磨堆焊参数及试验过程,进行了堆焊层耐磨试验及堆焊焊缝的显微观察,结合母材和堆焊焊接材料的成分特点及2种不同的堆焊工艺试验,对试验结果及工艺参数的选取进行了分析说明。Commencing from the partial building up and hard surfacing repair direction in roller,briefly present the cold working roller type of Cr3 wearable capability building up and hard surfacing craftwork parameters and the process of experimentation.Carry through building up and hard surfacing floor wearable experimentation and the microstructure observing of welding line,combining the component characteristic of base metal and welding material,the experimentation of two different welding craftwork,do some correlation analysis about the result of experimentation and craftwork parameters.
