CATEGORY

TYPE

The first Basic under water welding electrode with extreme low carbon content.

APPLICATIONS

Welding standard ship steel grades A, B & D in submerged conditions in case standard well known underwater electrodes fail to offer proper ductility and crack resistance exceeding the requirements for AWS D3.6M-99.

PROPERTIES

AquaForce LC is the first Basic electrode that was developed with "Hydrophobic sand" to offer maximum moisture resistance. AquaForce LC is currently the only available electrode that is able to produce flat (not concave) welds with deeper penetration in all positions including PB, PC, PD, PE and PG position. The special (Armcore) ultra low carbon core wire of this electrode reduces the hardness from 195 HV to 165 HV hardness in the pure weldmetal caused by the high cooling rate (T8-5) when welding under water. AquaForce LC`s unique Basic coating reduces Oxygen content in the weldmetal to obtain better ductility than can be achieved with standard wet welding rutile electrodes.
