Grind and Polish Stainless Steel Welds
Welding is an invaluable trade skill for mechanics, technicians and artists. Grinding and polishing steel welds is a great way to enhance the aesthetics of your weld. Welds look burnt and unsightly when they are first finished. Adding a shine to your weld will make it look as good as it is strong.
Instructions
1
Secure the weld on a vice or pipe clamp.
2
Attach a grinding disc to the grinder and use it to remove any excess metal from the weld. Excess metal is protruding and bubble-shaped. A clean weld is subtle and looks intentional. Use caution when grinding welds as sparks from the grinder can cause burns and other injuries.
3
Lightly heat the weld with the acetylene torch. Less heat is better than too much heat, as it could compromise the integrity of the weld. A red--hot weld indicates too much heat.
4
Grind the weld with the brush grinder. Use light pressure when grinding. The grinder spins quickly so high pressure is not necessary. Lightly grinding the weld may take longer but will provide a more desirable result. Grind from the highest point of the weld to the lowest point or from one side to the other.
5
Wait a few minutes to ensure the weld is cool. Brush off the weld with the hand brush applying high pressure. Carefully examine the weld for small splits and indentations and eliminate them with the brush.
6
Clean off the weld's stray particles with the air compressor. Examine the weld to make sure that it is clear before continuing.
7
Pour a small amount of steel polish onto a rag. Gently apply the rag to the weld. Continue until the weld has an even--looking shine.
8
Repeat steps three through six to improve the quality of the weld's polish. Remember to gently grind with the electric grinder.
