Description
Characteristics:
LKE-6019 is an ilmenite type electrode and can be used in all-position welding. It has excellent mechanical properties and X-Ray performance, stable arc, and good weldability. The weld bead is good with deep penetration and hardly causes slag inclusion.
Applications:
It is important structural objects such as ship body, boiler, vehicle frame, oil tank, steel frame and suitable for structural steels, steel strip, thin steel plate, fabrication steels
Notes on Usage:
1.Dry the electrodes at 350-400oc for 1-2 hours before use.
2.Keep the arc as short as possible to prevent moisture pick-up.
3.Take the back-step method to prevent blowholes at the arc starting.℃
