Agglomerated, semi-basic, Calcium-Silicate flux with Manganese support for SA-overlay welding and shape-forming using single or multiwire (TWIN-ARC) processes. EN 760: SA CS 1 75 AC is particularly designed for the repair of worn pistons for large ship diesel engines.

The weld bead exhibits a flat smooth surface with good wetting and self-lifting slag detachability without residuals even at high intermediate welding temperatures above 300 °C. Stable chemical flux reactions and constant operating characteristics over a wide current range, also when welding AC, are advantages of this flux. Low consumption as well as low humidity are additional features of EN 760: SA CS 1 75 AC together with low sensitivity to arc-blow and high resistance to porosity.

Application

EN 760: SA CS 1 75 AC is to be welded DC (+ or –) or AC in combination with non-alloyed and low-alloyed wires for overlay and build-up welding of heat-treatable, low-alloy steels which require preheat and interpass temperatures above 300 °C up to 500 °C.
Especially applied for recondition welding / form-welding of worn piston ring grooves and the surface of piston crowns.
