WC型管状焊条焊芯填充率对堆焊金属表面硬度的影响

INFLUENCE OF CORE FILLING EFFICIENCY OF WC-CORED ELECTRODE ON THE SURFACE HARDNESS OF SURFACTING LAYER

WC型管状焊条是一种高硬度、高耐磨性的堆焊焊条 ,广泛用于强烈磨损的零件上。通过实验研究证明

WC-cored electrode is a repair welding electrode with high hardness and high wear resistance, which has been widely used in circumstance with violent wear. The study discovered that the hardness of hard-facing layer produced from WC-cored electrode has a relationship with the core filling efficiency.
