The high-alloy OK 68.81 welding electrode produces a ferritic-austenitic weld metal with approximately 40% ferrite. It is ideal for dissimilar steel joints, materials with limited weldability, and for buffer layers in surfacing.
The OK 68.81 welding electrode is designed for applications where a reliable weld is required when joining different types of steel or materials that are difficult to weld. Thanks to the ferritic-austenitic nature of the weld metal, it provides stable weld properties and is also suitable as a buffer layer in surfacing.
Applications:
- Dissimilar steel joints
- Steels with limited weldability
- Buffer layers in surfacing
