Description:
Elgaux 285B is an agglomerated, slightly Si and Mn alloying, aluminate-basic ux. It combines very
good operability (slag removal, bead shape, bead nish) with low micro-oxide levels, enabling it to
produce good impact toughness down to -40°C / -60°C. It is suitable for butt and llet welding using
single, twin-arc and multi-wire processes. Together with the appropriate Elgasaw wires, Elgaux 285B
is designed for C-Mn and low alloy steels for low temperature and high strength applications. Elgaux
285B can be used on AC and DC, with up to 1000A on a single wire and is especially suitable for line
pipe fabrication, pipeline production, pressure vessels, offshore structures and wind turbine tower
manufacture.
