摘要
介绍铜管拉拔机关键部件拉拔卷筒孚用熔化极药芯焊丝气体保护焊堆焊耐磨层的堆焊工艺.堆焊材料选用抗裂性好的PK-YD212焊丝,单层硬度>HRC50.所确定的堆焊工艺可行,工件不预热,熔合区窄,堆焊合金稀释率低.
The hardfacing procedure with flux cored wire gas shielding process used for hardfacing rolling cylinder in copper tube drawbench is introduced in the paper. PK-YD212 flux cored wire is selected with good anti-cracking property,the hardness of layer will reach HRC 50 and more-the procedure is feasible ,without preheating and with low dilution rate of hardfacing alloy.
