Description

Electrode for copper alloy welding

Classification

AWS A5.6 : ~ E Cu
DIN 1733 : EL-CuMn2
UNS : W 60189

Properties and application

Basic coated electrode designed for welding various copper and copper–nickel alloys.

Also suitable for joining and surfacing of dissimilar non-ferrous metals.

The tensile strength of the weld is similar to the base material.

Application: electrical connections, metallurgy, shipbuilding, chemical industry.

Electrode diameter: 2.5; 3.2; 4.0 mm

Recommendations

Clean weld surfaces and cracks from grease.

Use a short arc and keep the electrode slightly inclined (10–20°).

Weld slowly to improve gas release.

Materials up to 5 mm thickness can be welded without preheating using suitable electrode diameter.

Preheat thick parts to ~500°C.

Dry if necessary for 2 hours at 150°C.
