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.
