It is desirable to be able to adjust the flux depth, depending on the amount of molten metal in the bead. Figure 6.
Stainless Steels Welding Guide - Lincoln Electric
stainless steel is generally helpful in welding. Less welding heat is required to make a weld because the heat is not conducted away from a joint as rapidly as in carbon steel. In resistance welding, lower current can be used because resistivity is higher. Stainless steels which require special welding procedures are discussed in later sections. 3.1 FERRITICStainless Steel Weld Finish Comparison - Custom Metalcraft stainless steel balls Strip surfacing weldingAbrasive buffed to masking line.

Passivation basics: Will this stainless steel rust?
Nov 11, 2018 · Welding creates a heat-affected zone and heat tint in which the alloy structure of stainless steel is altered. Heat tint is a thickening of the naturally occurring oxide layer on the surface of stainless steel. As heat tint colors are formed on stainless steel, chromium is drawn from below the surface of the metal to form a chromium-rich oxide stainless steel balls Strip surfacing weldingLaser Welding of Stainless SteelsThis series of stainless steel is suitable for both pulsed and continuous wave (CW) laser welding.
