▎Welding Position

▎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: 160~190°C, PWHT: 675~705°C

▎Application

It is ideal for welding high pressure steel pipes and heat exchanger steel pipes
