Description:
Elgacore DWA 55L is a rutile flux cored wire designed to meet extremely high weld integrity demands
in applications such as offshore fabrication. The micro-alloyed design, in combination with the 1.5%
Ni alloying level, produces exceptionally good fracture toughness down to –60°C. Impact strength is
tolerant to a wide range of heat-input and preheat/interpass conditions. The all-positional wire
operates with a smooth but forceful arc to give very good penetration characteristics when welding
horizontally, combined with high deposition rates when welding vertically up. Elgacore DWA 55L is
extensively CTOD tested from –10°C down to –40°C. Results from 50 & 60mm plate thickness show
CTOD values of 0.40 - 0.80mm at –40°C.
