ESAB’s neutral OK Flux 10.99 made for SAW in heavy industry

ESAB has enhanced its OK Flux 10.99, an agglomerated neutral basic flux designed for SAW in heavy industrial environments like petrochemical plants, offshore construction, transport, LNG and LEG tanks, pressure vessel, and pulp and paper industries. The enhanced formula of the flux works in combination with selected austenitic and nickel-based wires, performing equally well with either AC or DC+ current.

According to the company, the high basicity of the flux provides superior impact and toughness. Its weldability in 1G and 2G positions is smooth, with easy-detaching slag. The end result is a clean bead shape and appearance with good wetting, says the manufacturer.

As a neutral flux, it will not contribute any alloying elements to the weld metal. When combined with nickel-based products, hot cracking is decreased.
