Welding of mild steel and 490MPa high tensile strength steel for machinery, structures, steel frames, ships, bridges, towers, chemical engineering apparatus, rolling stock and cans.
NSSW SF-1 is a rutile type seamless flux cored arc welding wire to be used with CO2 shield gas. Arc is stable, spatters are few and bead is smooth with good shape and appearance since easily removable slag covers bead evenly. The diffusible hydrogen content is as low as that of solid wires since the wire has no seam and, consequently, weld metal shows excellent crack resistance. Welding fume is also less. It assures high welding efficiency since deposition rate is high and all-position welding is easily performed with almost the same current.
