▶︎ Characteristics:
LKE-7016 is a low hydrogen type electrode for the welding of high tensile steel. The welding can be done with stable arc, less spatters, good slag removability, good slag covering and good X-ray soundness.
▶︎ Applications:
It is suitable for low alloy steels, medium carbon steels, heavy steel plates, cast steels and steels of poor weldability. Due to good X-ray and mechanical properties, LKE-7016 is used for skill testing and competition by choice.
▶︎ Notes on Usage:
1. Dry the electrodes at 300-350°C for 60 minutes, and keep at 100-150°C before use.
2. Take the back step method to prevent blowholes at the arc starting.
3. Keep the arc as short as possible.
