AquaSan Ni50
1 / 2Pages

AquaSan Ni50 is a specially formulated, nickel based covered electrode with a waterproof coating for the welding of high strength steels with a Carbon Equivalent (CE) >0.4. AquaSan Ni50 is specified for welding base materials with a CE >0.4, which are susceptible to hydrogen embrittlement. Nickel has a high affinity for hydrogen and this composition allows hydrogen to diffuse into the weld metal and away from the high strength steel. STANDARDS - AWS A5.35: (pending initial publication).
