Selectarc Flux UP LA02

This flux is designed for submerged arc welding (SAW) of various steel grades, including unalloyed, low-alloy structural steels, fine-grained steels, and pipe steel qualities. It offers a high current-carrying capacity and is particularly suitable for tandem arc configurations. The flux formulation minimizes diffusible hydrogen levels and facilitates easy slag detachment, even in narrow groove welds. It’s compatible with both DC and AC welding, adaptable to various welding techniques (Single, Tandem, Twin, or multi-wire). It’s recommended for use with wires conforming to ISO 14171-A (AWS A5.17) S1, S2, S2Si, S3Si, S2Mo, and S2Ni2.

FLUX UP LA02 is primarily utilized in submerged arc welding (SAW) processes across a range of steel applications. It’s ideal for shipbuilding, heavy fabrication, pipe manufacturing, and general structural steelwork. Its low hydrogen content and easy slag removal properties contribute to high-quality weld beads and reduced post-weld heat treatment (PWHT) requirements. The flux’s versatility allows for adaptable welding strategies, accommodating diverse joint geometries and welding configurations. It can be used with various wire alloys to achieve desired mechanical properties in the weld metal.
