Weld Mold® 960


Weld Mold 960 produces a superior high tungsten hot work deposit that resists heat, abrasion and shock, and maintains its hardness at elevated temperatures. Can be used in all positions with excellent results. Completely heat treatable.

Applications

Examples include; heavy duty hot shears, forging die inserts, hot punches, extrusion dies, brass forging dies, hot trimming dies, and other units that operate at a dull red heat.

Procedure

Use AC or DC, reverse polarity. Prepare area to be welded by removing all cracks, heat checks or other defects. Clean area of any slag, scale, rust or drawing compounds. Preheat die blocks and other units where the entire working surface is to be welded to 800º F. On other alloys preheat and post-heat according to the base metal. Maintain temperature during welding. Hold electrode on a slight angle in the direction of travel and maintain a short arc gap. Use the stringer bead technique. Peen the weld when hot to relieve stresses. After welding cool in still air to 300º F to obtain the ultimate grain refinement and uniform hardness in the weld deposit. Post-heat at 1000º F. Hold at temperature for one hour per inch of thickness. Cool in still air to room temperature.
