Description :

SS-309MOL-16 is rutile electrode used as buffer layer in welding acid resisting clad steels with better crack resistance and corrosion resistance. It is also suitable for welding dissimilar steels and steels difficult to weld.

Applications :

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.
