Product description

Suitable for welding dynamically loaded structures, like bridge, heavy steel construction, pipeline joints, tanks, pressure vessels, boilers and machinery, where high strength and toughness are required. The weld metal has low diffusible hydrogen and high notch impact toughness down to -40°C. It has 115% weld metal efficiency. Provides smooth and clean weld beads, mixing with the base metal without undercut. Good gap bridging and position welding capability. The welds are of X-ray quality. It is also suitable for making buffer passes in high-carbon steels.
