DAIKOWS 700

Designed for welding quenched and tempered, as well as thermomechanically rolled fine-grained structural steels and high-strength tubes, these consumables yield exceptionally tough weld metal at low temperatures. Their notable deformability makes them well-suited for crane, building, and vehicle constructions. The precise addition of micro-alloying elements ensures excellent ductility and crack resistance despite the high strength. Preheat considerations should align with the base material and thickness, with materials intended for welding by these high-strength consumables typically requiring a minimum preheat of 100°C. Caution is advised with certain HSLA steels, as interpass temperatures exceeding 200°C may lead to reduced strength and toughness. Post-weld heat treatment (PWHT) requirements generally hinge on the base material and application.
