TYPICAL APPLICATIONS

Cold welding of grey and malleable cast iron, cast steel and for joining these base metals to steel, copper and copper alloys, especially for repair and maintenance.

WELDING INSTRUCTIONS:

• Depending on the wall thickness, the preparation is made in U-or double U-form.
• The casting skin has to be removed on both sides of the welding area. Hold the electrode vertically with a short arc. Thin passes are buttered, their width not more than twice the diameter of the core wire.
• To avoid over-heating, the beads should not be longer than 10 times the electrode diameter.
• Remove the slag immediately after welding and then peen the deposit carefully.
• Reignite on the weld deposit and not on the base metal.
