Description:
Elgacore DWA 51B is a basic flux cored wire with excellent operating characteristics and is suitable
for steels with a tensile strength up to 600 N/mm2. It produces weld metal with superior crack
resistance under difficult conditions of high restraint and exhibits good low temperature fracture
toughness. Weld deposit hydrogen levels are typically 3 ml/100 g. Elgacore DWA 51B welds with a
stable arc and gives high deposition rates with low spatter levels in the flat and horizontal-vertical
positions.
Applications:
Recommended for multipass welding of medium and thick section carbon-manganese steels used for
shipbuilding, bridge construction and heavy machinery and plant.
