Weld Mold® 880
Weld Mold 880 is for high tensile joining of crack sensitive materials that don’t require heat-treatment. The exceptionally high elongation and tensile strength of this machinable alloy makes it a highly versatile maintenance material. Deposits are dense, smooth, crack desensitized and resistant to corrosion and heat.
Applications
Use 880 for joining cracked die sections, tool steels, high manganese, high carbon, low carbon, and stainless steels. Examples include: hot and cold shears, drill shanks, springs, drill shank extensions, and tap extraction. Use 888 for welding heat treatable tool steels.
Procedure
Prepare unit by removing all foreign material, fatigued metal, and any sharp radii. Bevel heavy sections to be joined. On high alloy tool steels it is advisable to preheat according to the base metal to obtain optimal results. Generally, on other applications preheating is not necessary. Peening will help relieve stresses and is advisable when welding on high alloy materials.
