DEOXIDIZED COPPER
WWW COPP WELD (ER Cu) filler
metal is deoxidized copper with small quantities of phosphorus,
silicon, tin, manganese and silver. The phosphorus and silicon are
primarily deoxidizers, and silicon and other elements improve fluidity
and ease of welding. This metal is normally used to weld deoxidized
copper (C12000 and C12200) and electrolytic tough pitch copper (C11000).
Preheating is desirable for most work, but it is essential for heavier
gauge welding. Preheating temperatures of 400ºF to 1OOOºF (205ºC
to 540ºC) are suitable.
