AWS A5.4 : E310
▶︎ Characteristics:
LKE-8012-C2 is an iron powder low hydrogen electrode for the welding of low temperature service steel. The weld metal contains 3.5%Ni. Good impact value can be obtained at -73°C. The welding can be done with good X-ray soundness, high deposition rate.
▶︎ Applications:
It is suitable for the welding LPG tanks or 3.5%Ni steel for low temperature service.
▶︎ Notes on Usage:
1. Dry the electrodes at 300-350°C for 60 minutes before use.
2. Do not exceed the proper range of current, otherwise impact value will decrease.
3. Take the back-step method at the arc starting.
4. Keep the arc as short as possible.
