Description:ER3103 is aluminum alloy welding wire containing about 1% manganese.
Characteristic:Besides the excellent welding performance,fine and bright welding appearance, this wire also has the features of corrosion resistance,high strength(comparing with pure aluminium), good weldability and plasticity. After the anodization treatment, the color is in good matching.
Application: Applying for argon arc welding of 3XXX series alumal, and as filling materials of gas shielded welding.

Attention
Please remove the oxide film and grease of edge-weld and surface of welding wire from the welding parts Strictly , or it will form lack of fusion on welding line and cause blow hole, slag inclusion and such other defects.
To keep weld penetration without collapsing,please hold the melt metals by cushioning when weld the wire.
