Weld Mold® 312


Weld Mold 312 is a smooth running, porosity-free, very low spatter, austenitic stainless steel alloy.

Applications

Recommended for welding type 312 stainless steel. Also for welding mild, high-strength and high-yield steels to stainless steel, plus numerous dissimilar combinations. Uses include general fabrication of analogous materials, tool repair and work-hardening underlays prior to hard-facing.

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.
