SMAW can be a messy process that leaves a lot of slag leftover, but an angle grinder is an effective way of removing it. The angle grinder also grinds down weld beads when performing root and fill passes in pipe welding. [8]

At every process upstream, most precision sheet metal fabricators employ at least some level of automation. But there's no getting around it: Grinding down a weld on a formed workpiece is and probably will remain an intensely manual operation. The act of grinding can be deceivingly simple. But the devil's in the details.

What is Grinding? Put simply, grinding is the process of removing excess material using an abrasive wheel. The two uses for grinding in the welding realm are prepping a workpiece for a more structurally sound weld, or smoothing out the seam after bonding two pieces of metal to produce a nice finished piece.

Metals. Welding is a process conducted at high heat, melting the base material, usually with the addition of filler material. In that way, it's different than brazing and soldering. The high heat creates a weld pool of molten metal. When the melt cools, it forms a joint stronger than the parent material.
