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. WELDING of tools may be required for the following reasons: Refurbishment and repair of cracked or worn tools Renovation of worn or chipped cutting edges, on cutting tools Adjustment of machining errors Design weldability of steels with high carbon content is usually considered to be poor.
