Characteristics:
LKE-10018-G is a low hydrogen electrode for the welding of 690 N/mm2 grade high tensile steel. With excellent crack resistance, good mechanical property and bead appearance.
Applications:
It is suitable for build-up welding before hardfacing. Proper base metals are forging cast iron, structural steel(HT70), pressure vessel(ASTM A225 Gr.C), carbon steel plate for mechanical fabrication(S45C),SAE 1345, ect..
Notes on Usage:
1.Dry the electrodes at 350-400 °c for 60 minutes and keep at 100-150 °c before use.
2.Preheat the plates at 100-150 °c is before welding.
3.Keep the arc as short as possible.
4.Take the back-step method at the arc starting to prevent blowholes.
