Union S 4 Mo – UV 420 TTR is a wire-flux combination designed for submerged arc welding (SAW) of unalloyed and low-alloy steels. It is suitable for single-wire (DC) welding. It provides excellent slag separation even in narrow-groove welds. The flux is particularly suitable for multi-pass fillet welding of medium-strength steels. It ensures good impact toughness in the weld metal at low temperatures. |
