Properties and Applications | Slagless metal powder cored electrode with outstanding welding properties in the short arc and spray arc range. Almost spatter free when welding in the spray arc range with mixed gas. Good restriking, even with cold wire tip, thus being suitable for robot application. Characteristic features; high deposition rate and welding speed, good side wall fusion, finely rippled welds, without undercutting into the base metal, not even on contaminated or corroded metal surfaces. Weld metal has a little formation of silicates on surface, so that multi pass welds can be made without cleaning. FCW 21 is well suited for root and positional welding and gap bridging, due to it's easily controllable weld pool in the short arc range. |
