DW-A51B is a fully basic FCW which produces very low hydrogen weld metal of excellent crack resistance.
This wire is particularly suitable for multipass welding of medium to heavy sections where conditions of high restraint exist and where extra low hydrogen levels are necessary.
DW-A51B is also often applied in situations where an ideal joint fit-up can not be achieved, leading to an increased risk of cracking when applying other welding consumables, for example when welding root passes on ceramic backing.
