Applies to re-melt deposit welding process of high-hardness hot-working tools. For example, it’s used for comb dies (trimming dies), drawing and pressing tools, hot plate welding machine, and continuous casting roller etc. It’s also can be used for welding-repaired cold-working steel, hardware stamping dies, forming dies, hard-surface of workpieces and manufacturing laser welding wire with high hardness, wearing resistance and high tenacity.

The hardness of re-melt deposit materials mainly depends on parent materials and its chemical compositions. But these influencing factors will decrease with the increase of welding layers.
