Tool Steel Welding Specifications

Tools and mold parts are welded for various reasons. Some of
these reasons include:

– Design changes
– Correction of machining errors in tool making
– Repair of cracked or worn tooling

Tool steels are generally considered to exhibit poor weldability
due to the deep hardening and chemistry of these grades. Weld
deposits cool quickly when the heat source is removed and the weld
metal and surrounding heat affected zone will harden. Stresses from
this hardening transformation are normally high and risk of cracking
is possible.
