19 Procedure:
Wear-Arc 40 electrodes have good welding
characteristics in flat and vertical-up positions. Weaving
technique or stringer beads may be used.
Limit deposit thickness to two passes. Area
Covered per Pound, 1/8" (3.2 mm) Depth—
20-24 in.2
(129-155 cm.2) Typical
Mechanical Properties: The
weld metal deposit of Wear-Arc 40 cannot be forged at any temperature and does
not respond to heat treatment.
Weld deposits cannot be cut with oxy-acetylene torch or by air carbon-arc cutting.
