▎Applications and Features
- KL-816B1 is suitable for welding Cr-Mo alloy steel.
- Weld metal contains 0.5%Cr-0.5%Mo
- It is ideal for welding boilers, petro-chemical plants, forged steel and alloy steel。
▎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 boilers, petro-chemical plants, forged steel and alloy steel。
