Precautions
1.The flux shall be dried at 300–350 °C for 2 hours before use.
2.Prior to welding, remove all impurities from the base metal surface, including rust, primer, oil, grease, carbon-arc gouging scale, and welding slag.
Description:
1. A submerged arc welding wire designed for 550 MPa high-strength low-alloy steels, compatible with grades such as Q420, Q460, 18Mo, 12MnV, and 15MnV.
2. During welding, it delivers a stable arc, easy slag removal, and a smooth, well-formed weld bead.
Applications:
Shipbuilding, wind power, chemical processing, steel structures, bridges, boilers, and pressure vessels.
