Descrizione
Caratteristiche:
LKE-11018-G is a low hydrogen electrode for the welding of 760 N/mm² grade high tensile steel. With excellent crack resistance, good mechanical property, bead appearance and lower moisture pick up. It is provided with good arc and easy slag removal.
Applicazioni:
It is suitable for welding of TSTE 620V and TSTE 690V high tensile steel.
Note sull'uso:
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°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.
