HPP 562

                         COPPER

ELECTRODE FOR WELDING COPPER

GENERAL CHARACTERISTICS

Smooth running high purity copper electrode designed for both overlay and fabrication of conventional grades of copper and copper alloys. 

TYPICAL APPLICATIONS:

For surfacing, build-up and fabricate electrolytic and deoxidized copper parts.  Ideal for applications requiring high corrosion resistance, thermal and electrical conductivity.  Also commonly used to copper clad steel and cast iron, especially heavy sections.

Procedure:  Clean joint area of all oxides and other foreign material.  Bevel sections which are more than 3/16" thick.  Thin gauge sections do not require preheat but heavier sections require preheating to 750 1100 degrees F.  Use the largest diameter electrode possible and maintain a short arc.  Allow to cool before removing slag.
