PHILARC COPPER
AWS Specification : AWS A5.6 E Cu
JIS Specification: DCu
Other Specification: AC/DC
I. APPLICATIONS:
Welding of pure copper. Repairing welding of electrode holder, flange, etc. Also suitable for repairing welding of the parts which required electric conductivity.
II. DESCRIPTION:
PHILARC COPPER is the covered arc welding electrode which is used with DCRP (electrode positive) for pure copper. It is designed for use without preheating and shows deep penetration. Therefore, plate thickness up to 16mm can be welded without edge preparation, then you can obtain the maximum efficiency. However, preheating at 100~200ºC still offer a high quality welding and good penetration at arc starting. PHILARC COPPER produces high purity copper weld deposits. Corrosion resistance and electrical conductivity is excellent. Perfect color match to copper. Welding of pure copper suitable for repairing welding of the parts which require PHILARC COPPER used to surface, build-up, and fabricate electrolytic tough pitch and oxygen-free copper. Excellent for applications that require high corrosion resistance. Commonly used to overlay steel or to join heavier sections of copper to steel.
Common bronze should not be preheated above 150ºF. Pure copper requires a 900ºF to 1000ºF preheat, while all other copper base alloys require a 500ºF to 700ºF preheat. Thin sections or steel do not require preheating, however if the base metal is warmed a lower amperage can be used. Using DC reverse polarity (electrode+) and the largest diameter electrode as possible, maintain a short arc length.Stress and distortion can be avoided by peening each deposit between passes. Allow the part to cool slowly before removing slag with a chipping hammer and wire brush.
III. NOTES ON USAGE:
Preheat thicker sections to 750º-1100ºF (400º-600ºC). Use as large an electrode as possible and maintain a short arc.
