Selectarc Flux UP LA03
This flux is specifically designed for submerged arc welding (SAW) and surfacing of various steel types, including low-alloy structural steels, fine-grained steels, pipe steels, and boiler steels. It offers a high current-carrying capacity and is formulated to minimize diffusible hydrogen levels, ensuring excellent weld quality. The flux facilitates easy slag detachment and is suitable for both DC and AC welding processes utilizing single, tandem, twin, or multi-wire configurations. It’s recommended with wires conforming to ISO 14171-A AWS A5.17, and is compatible with special hard facing wires and strips.
This flux is ideal for applications requiring robust welding and surfacing of steel, particularly in demanding environments such as shipbuilding, heavy machinery fabrication, and boiler construction. It’s suitable for use in automated SAW processes and allows for versatile welding techniques. The flux provides excellent weld metal properties when post-weld heat treated (PWHT) following specified temperature and time cycles.
