1 LB - 3/32" Vulcan NastyCast Cast Iron Repair Electrodes

Procedure: Clean weld area if possible. Remove surface skin and all sharp edges. Bevel joint to form a U-groove. A bead hole must be welded at right angles to each end of all cracks to prevent spreading. Use low amperage and maintain a short arc. Short stringer beads or narrow weave beads should be used to prevent excessive heat build-up. When breaking the arc, always fill the crater and drag rod back over the weld deposit. Peening while still hot will help reduce stress. When restriking the arc, start on previously deposited weld metal, not on the base material. Allow part to cool slowly.
