Instructions
1. Disinfected the metal where it has cracked with a metal grinder, going 1/2 inch bygone the field where you are going to weld until it is aglow and shiny.Split throw steel can be welded back calm.Toss steel tends to crack and wear down when overexposed to alpine amounts of heat. Shy steel welding is a bit enhanced difficile than other types of welding repairs by reason of not all items prepared elsewhere of cast steel are created the identical groove. Welding cracked fling steel takes patience and diligence.2. Bevel the surfaces of the edges of the crack that is to be repaired with a peeling and shearing bevel.
Drill with a tap attachment threaded holes into the limit of the crack that are going to be welded back together. The holes should face toward the main body of each cast steel piece.
3. Insert steel studs into the threaded holes, making sure to leave 1/4 inch of the stud above the surface. Weld the studs into place by heating them and their surrounding metal with the MIG welder until it has melted. Add molten weld metal if necessary to secure the studs into place.
4. Place the setting on the MIG Welder to low current. Run a bead of molten metal around the bottom edge. Start by welding in small 1 inch circles to prevent buildup of residual stresses. Add weld metal in progressively narrowing circles until the hole is closed at the bottom. Start adding metal, one layer at a time, until the hole is filled, taking care to make every layer fused to the one below it.
