Ditch the Abrasive Grinder Discs. An angle grinder fitted with an abrasive metal-cutting disc works well to cut all kinds of metal, including bolts, angle iron, rebar and even sheet metal. But the discs wear down quickly, cut slowly and shrink in diameter as you use them. Instead, we recommend using a diamond blade that's rated to cut ferrous metal.

Thoroughly grind off the coating around the area you're going to weld. You want to grind off more than the exact size of the weld and should remove at least two inches of coating above and below the weld zone. After grinding, wipe the piece down with a dry cloth. If you're joining two pieces, remember to remove the coating on both pieces. 4.

Fine grinding produces a surface with little deformation that can easily be removed during polishing. Because of the drawbacks with grinding papers, alternative fine grinding composite surfaces are available, in order to improve and facilitate fine grinding, A high material removal rate is obtained by using grain sizes of 15, 9.0 and 6.0 µm.

The act of grinding can be deceivingly simple. But the devil's in the details. Effective grinding requires operators to apply enough pressure at the correct angle to let the grains—the "cutting tool" of a grinding disc—remove the most metal in the shortest time, while not prematurely wearing the disc or burning out the grinding tool.

This can range from grinding and wire brushing to merely wiping the part with a rag moistened with the cleaner/ remover. The surface needs to be free of dirt, rust, scale, paint, oil, and grease, and be smooth enough to wipe off the penetrant without leaving residue.

Trace particles from iron or carbon steel will rust stainless steel surfaces. If left unattended, rust spots may compromise the chromium oxide surface and evolve into localized corrosion such as pitting. Contamination occurs when stainless steel is subject to sparks or particles from nearby welding, cutting, drilling, or grinding of carbon steel.

Most grinding or honing shops are technically qualified to grind or hone chromium. If help is needed in this area, your qualified chrome plater can be of assistance. Almost any required finish can be obtained on chrome plate. In thickness ranges of 0.001 to 0.002 inch the asplated surface will be only slightly rougher than the base metal.

First, hard chrome is deposited straight on the steel. You don't want a soft material under it. The typical solution is 33 oz/gallon chromium trioxide and .33 oz/gal sulfuric acid, no brighteners. You normally want more than a thouh of chromium to make it hard and usually build up more, then grind. Grinding is not a problem.
