Weld Mold® 943
Weld Mold 943 produces an exceptionally high shock resistant, dense, and completely heat treatable weld deposit. Suited for medium hot and cold working units, and metal-to-metal wear areas. Retains high hardness to 600° F. Deposits take a high polish.
Applications
The wide versatility of 943 makes it ideally suited for many applications. Examples include; die cast dies, cold shears, header dies, chisel and punch points for air hammer tools, blanking and bending dies, trimmer dies, and sledgehammer faces.
Procedure
For repairs remove all cracks and heat checks by grinding or other suitable method and clean area of all oxides and foreign matter. Preheat A.I.S.I. “S” series tool steels to a maximum of 600º F. Be sure unit does not exceed 600º F during any phase of the welding operation. On other base metals preheat and post-heat accordingly. Deposit stringer beads. Peening is advisable. After welding, cool in still air to 150º F. Temper at 600º F at one hour per inch of thickness for maximum hardness.
