Arc Welding Service

CATEGORY

TYPE

Fused flux with very low hydrogen content for SAW welding.

APPLICATIONS

Boiler works, pipes, ship building, structural steel works, tanks and pressure vessels, offshore applications etc..

PROPERTIES

Glassy melted (fused) low- manganese metallurgical neutral flux. Suitable for direct- and alternating current welding at high current up to 1000 Ampere per wire and 1400 Ampere for multiple wires. FL CS 165 ensures high toughness properties of the weld metal and is suitable to weld plates of unlimited thickness.

Basicity:            ~1,3 (according to boniszewski)
Grain size:        0,32÷1,6 mm
Density:            1,4÷1,7 kg/dm³
