Description
Characteristics:
LKE-8018-C3 is an iron powder low hydrogen electrode for the welding of low temperature service steel in all positions. The weld metal contains 1.0%Ni. The welding can be done with good X-ray soundness, high deposition rate, and good impact value at -45°C.
Applications:
It is suitable for the welding of LPG tanks.
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 the impact value will decrease.
3.Take the back-step method at the arc starting.
4.Keep the arc as short as possible.
