SAW Submerged arc
Submerged arc welding wire for high strength fine grain steels with >690N/mm2 yield strength.
Applications will be found in the offshore industry, shipbuilding, pressure vessels, earthmoving equipment, cranes and general structural fabrication.
Welding procedure (including preheat temperature, interpass temperature and PWHT) will be dependent on the base material being welded, including its thickness, and any applicable design codes. Remarkable crack resistant weld metal in combination with very low hydrogen content. Therefore, suitable for the economic processing of high-strength and low temperature fine grained structural steels. Excellent welding properties in combination with FL 155 high basic flux even in narrow gabs. To obtain optimum mechanical properties the heat input should be kept below 15 kJ/cm and interpass temperature between 100 and 150ºC.
