Base Materials

Weathering steels and special structural steels: S235JRW, S235J2G3Cu, S355J2G1W, S355J2G3Cu and Corten A, Patinax 37
suitable fluxes BF 3, BF 4, BF 5.1, BF 6.5 and BF 10

Flux type suitability is strongly dependent on its application. In combination with the wire electrode the most suitable flux should match the requirements of the plate material as closely as possible under the existing welding conditions. Further information can be obtained from the technical flux data sheets.
