The key to joint design is creating a joint that limits the number of weld passes required (especially on 1/4-in. and thicker austenitic stainless steel), and with it the amount of heat input. One way to limit these passes is to create a joint design consisting of a V-groove, modified V-groove, U-groove, or J-groove.

In some stainless steel applications, weld grinding is required as one of the last steps for finishing. 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.

Steel wire brushes are essential finishing tools in most metal fabrication shops. Fabricators can take five actions to help improve the performance and life span of these brushes: use the highest safe speed, periodically reverse direction; know when to use crimped or knot wire brushes; keep stainless steel brushes clean; and purchase heat-treated, oil-tempered steel wire.
