Aluminum and Aluminum Alloy Electrode

L109  

GB/T E1100

AWS A5.3 E1100

Description: L109 is a pure aluminum electrode with a salt-based coating. Use DCEP (direct current electrode positive). Try to use a short arc to weld.

Application: Used for welding aluminum plates and pure aluminum containers.

Chemical composition of weld metal(%):

Mechanical properties of weld metal:

Recommended current:

Notice:

1. The electrode is very easy to be affected by moisture, so it should be stored in a dry airtight container to prevent it from deteriorating due to moisture; the electrode must be baked at about 150°C for 1 to 2 hours before welding;

2. Backing plates should be used before welding, and welding should be performed after preheating to 200 ~ 300°C according to the thickness of the weldment; the welding rod should be perpendicular to the surface of the weldment, the arc should be as short as possible, and the replacement of welding rods must be carried out quickly;

3. The weldment must be cleaned of oil and impurities before welding, and the slag should be carefully removed after welding, and rinsed with steam or hot water.
