Weld Mold® 925
Weld Mold 925 produces fine-grained weld deposits of the carbon-vanadium type, which may be completely heat-treated to facilitate machining and then rehardened to the desired hardness.
Applications
Primarily used for repairing water hardening tools and dies including types W-1 thru W-5. Examples of tools include cold working units such as shears, trimmers, punches, dies, nibblers, and other cutting edges.
Procedure
Prepare area to be welded by grinding out cracks and other defects. Remove all oxides and other contaminates. Preheat water hardening tool steel units from 275º F to 450º F depending on their size, and maintain temperature during welding. Use a lower preheat temperature for small units that are subject to heat input from the arc. On materials other than water hardening, preheat to specified temperature according to the base metal. Deposit short stringer beads. Peen each deposit rapidly when forgeable. After welding, cool unit to 150º F in still air, then temper at 450º F for one hour per inch of thickness.
