Description
Caractéristiques :
LKE-8018-B2 is an iron powder low hydrogen electrode. The weld metal contains 1.25%Cr-0.5%Mo that makes the electrodes more suitable at 550°C ,With the characters of quiet and stable arc, little spatter.
Applications :
It is suitable for welding of piping steels (STPA22,23, A335-P11, P12), casting steels (A217-WC6), and forging steels (A182-F11,F12).
Notes sur l'utilisation :
1.Dry the electrodes at 350-400°C for 60 minutes before use.
2.Take the back-step method at the arc starting.
3.Keep the arc as short as possible.
