CLASSIFICATION
AWS/SFA 5.11: ENi–1

DESCRIPTION
A special basic coated electrode depositing low carbon pure nickel weld metal, deoxidised and refined with about 1.5% titanium. The welds are porosity free. Pure nickel weld metals are sluggish which may lead to bead irregularities which in turn require ante -run dressing.

TYPICAL APPLICATIONS

• Joining pure nickel to itself for buffer layer and for cladding joint faces and flanges, tanks and vessels, process pipe work, heat exchangers.
• In chemical plant : Salt production, chlorination and evaporation of caustic soda.
• Used for equipment handling corrosive alkalies and halides.
• For Joining low-alloy steels to Nickel-Copper alloys.

PROCEDURE

• Clean the area to be welded thoroughly.
• Use short arc with stringer bead.
• Dry the electrodes at 250ºC for 2 hrs.
