WELDING IN tool MAKINGA guideline for WELDING of cold work steels, hot work steels, high speed steels, plastic mould steels including PM steels WELDING IN tool MAKING 23 MATERIALS IN tool MAKINGI ntroductionTools often need to be welded. This is especially true for expensive tools such as die-casting dies, large forging dies, plastic moulds, car body dies and cut-ting and forming tools where repair and adjustment via WELDING is a highly cost-attractive and economic alternative to the expense of producing new tools.
The main problem in welding tool steel stems from its high hardenability. Thermal stresses concurrent with microstructure transformation occur during the cooling of the weld. This transformation may generate cracks in the welded area. Such reductions in
