TM-77 is a gas-shielded metal-cored wire that features smooth spray arc, slag-free welds, low spatter, low diffusible hydrogen low fume emission and excellent low temperature impact toughness down to -40°C. It welds with a wider penetration profile and higher deposition efficiency than solid wire.
Multi-layer welding can be performed without removing slag. It is suitable for steel structures, storage vessels and multi-layer welding on heavy plate thickness.
