A 'weld-done' finish - The Fabricator

  • Restoring The Hairline FinishThe Mirror FinishMaximizing Finishing EfficiencyGetting Around Corner WeldsWhen a hairline finish must be restored, use an elastic flap disk to remove the weld. One type of abrasive disk that does this is made from a compound developed specifically for grinding stainless steel. The fiber in the compound is derived from the hemp plant, which provides excellent abrasion while also being environmentally friendly. Heat absorbency is another characteristic of this material. When this type of abrasive flap disk is used on a variable-speed angle grinder at a maximum of 8,000 RPM, the grinding tStainless steel weld finishing by the numbersJul 07, 2014 · As the demand for stainless steel increases, welders and metal fabricators need to understand how to obtain the proper finish. Standard mill finishes usually are applied to flat-rolled stainless steel directly by the manufacturer. The fabricator then applies a final finish to the welded surface to achieve the desired aesthetic appearance.
