Application:

It is suitable for welding of carbon steel and low alloy steel structure, such as petrochemical industry, ships, offshore platforms and other important structures. For example, Gr.50.

Attention

1. Before welding, the electrode must be baked at 350-380℃ for 1 hour and used with baking.

2. Rust, oil, moisture and other impurities must be removed from the welds before welding.

3. When welding, it is necessary to use short arc operation, and the swing amplitude should not be too large, and it is appropriate to narrow weld.

4. In order to prevent the occurrence of arc initiation holes, arc initiation plates should be used for arc initiation or arc return welding.
