Description :

SS-309L is a titania electrode suitable for welding of 22Cr-12%Ni steel, dissimilar-metal joint, and surfacing of mild steel.

Application :

Typical applications include stainless steel piping in refineries and chemical plants. Corrosion resistance overlay on carbon steel, welding of carbon steel of poor weldability.

Note Of Usage:

1. Rebake the electrodes at 200°C for 1 hour and keep it at 100°C prior to use.

2. Use stainless steel wire brush for cleaning of slags.

3. Follow the recommeded welding parameters to achieve good sound welds.

4. Use lower current for dissimilar-metal joint.
