accumulation of dirty metal scale on the finished weld. Slag should be removed by using a chipping
hammer.
PEENING THE SLAG FROM A WELD JOINT CAUSES SMALL CHIPS OF METAL TO FLY
THROUGH THE AIR! Metallic chips flying through the air can cause eye injury or injury to
other parts of the head, hands or exposed portions of the body. Wear goggles or safety
glasses with side shields and protect the hands and other exposed parts of the body with
protective garments, or if possible, work with a shield between the body and the work piece.
The intense heat produced at the arc sets up strains in the metal joined by welding. Peening the
weld not only removes the scale left behind in the welding but relieves the internal strains developed
by the heating and cooling process.
