C189 Deoxidized Copper Electrode
Nominal Chemical
Composition
INTRODUCTION
Aufhauser Deoxidized Copper Electrodes are manufactured from deoxidized copper wire to provide the best mechanical and metallurgically sound joints. The deposit is free of porosity and gives a tensile strength similar to that of most commercial copper types. Reactions with hydrogen in oxygen-free copper, and the segregation of copper oxide in tough pitch copper may detract from joint efficiency. Precautions should be taken to minimize dilution effects. Preheating to 700 °F may be required.
APPLICATIONS
- Shielded arc welding (SMAW) of deoxidized coppers, oxygen-free coppers, and tough pitch (electrolytic) coppers
- Repairing or surfacing above-mentioned metals, as well as steel and cast iron
- Clad restoration on copper-clad vessels

ADDITIONAL INFORMATION
Copper and its alloys require a relatively high heat input with shortened welding time. Higher preheat temperatures and faster welding rates than for steel are necessary.
