▎Welding Instruction

  • Clean up the contaminations on the steel.
  • Dry the electrodes at 350~400°C for 60 minutes before welding.
  • Keep arc as short as possible. Take the back step method to prevent porosity at arc start and re-start. (Please refer to Appendix A).
  • Preheat and interpass temperature: 100~200°C, PWHT: 600~635°C.

▎Application

Ideal for welding steel pipes, heat exchanger pipes, cast steel, rolled and forged steel.
