Features and Applications
- Used for TIG welding of high heat resistance steels such as P91 / T91
- Power plants, turbines, oil refineries, cool and gasification plants, boiler production, also used for the welding of steels with 9Cr 1Mo
- Weld metal is resistant to working temperature up to 600°C
- The test assembly shall be cooled in the furnace to 300 °C at a rate not exceeding 200 °C/h
- Preheat and interpass temperature should be used at 200-315 °C.
- Shielding gas (TIG): Pure Ar
