Features and Applications
- Applicability in welding of heat-resisting steels containing 2% Cr - 1% Mn and similar alloys
- Electrode with basic-type coating
- Formation of more ductile and less hard weld metal due to low carbon content
- Serviceability at temperatures of values up to 600 °C
- Preheat and interpass temperature should be used at 200-300 °C
- The test assembly shall be cooled in the furnace to 300 °C at a rate not exceeding 200 °C/h
- Re-drying: 300-350°C / min. 2h
Current Type
- DC(+)
