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
GENERAL INFORMATION
Chemical Composition| Copper | Manganese | Iron | Silicon | Aluminum | Lead | Other* |
|---|---|---|---|---|---|---|
| >98.0 | 0.10 | 0.20 | 0.10 | 0.10 | 0.02 | 0.50 |
* Total other includes Zinc, Tin, Nickel, Phosphorus = 0.50%
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.
