Features and Applications
- Welding of heat-resistant Mo-alloyed, fine-grained or unalloyed steels used for construction of boilers and pipes
- Weld metal is resistant to working temperatures up to +550°C
- Preheat and interpass temperature should be used below 200 °C
- The test assembly shall be cooled in the furnace to 300 °C at a rate not exceeding 200 °C/h.
- Electrodes of this type give a smooth droplet transfer, which ensures that these electrodes are suitable for welding in all positions except the vertical down position.
Current Type
- AC
- DC(-)
