Grinding and Polishing Guide. Grinding and Polishing Guide.Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit sizeof 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel.

Having your skin covered is critical. Once you start grinding and welding,hot sparks and molten metal slagcan shoot in all different directions. We protect ourselves by wearing heat-resistant leather and natural fiber; synthetic fabrics melt instead of burn, meaning they become molten and burn into the skin, yikes! But honestly, a leather jacket is really hot to wear for any extended welding project.
