Material no.: 2.1006
AWS A5.7: ER Cu

Applications
For alloy-like joint welding of low-oxygen copper and wrought copper alloys and cast materials.
alloys and cast copper materials, e.g:
2.0040 - OF-Cu,
2.0070 - SE-Cu,
2.0076 - SW-Cu,
2.0090 - SF-Cu
and for build-up welding on copper alloys and unalloyed ferrous materials.
Welding of oxygen-containing copper grades with an O2 content of more than 0.02 % is not recommended.

Typical applications are
Components in the chemical, paper, food and textile industries as well as shipbuilding, conductor rails,
electrical contacts, pipelines, containers, flanges and fittings.

Processing instructions
Remove cracked and otherwise damaged material. Clean welding areas. During welding, adjust the heat input to the component, its material and dimensions; preheat solid workpieces to 600 °C.
Preferably weld CastoMag 45709 with an argon-helium mixture.
Weld with short arc, spray arc or pulsed arc, prefer pulse arc technology.
