Features and Applications
- Rutile type flux cored wire for all position welding
- Excellent weldability for vertical up position (PG) and overhead fillet (PD) position
- Good arc stability and weldability
- The PWHT schedule is as follows: 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 200-300°C.
- Shielding gas: 100% CO2 or Ar+CO2 mix
