Covered electrode Application: WE600 welded rail steel covered electrode special nickel-chromium alloy steel covered electrode, which is suitable for all-round welding. It has extremely wide universality, excellent welding process performance, stable arc and uniform and beautiful weld.

Technology and precautions:

1, preheat 200℃~400℃ before welding.

2, try to use small current, first in the groove surfacing, and then welding.

3, covered electrode drying.

4. Hammer the weld.

5. Immediately after welding, heat the welding part to 600℃-650℃, keep the temperature for 30 minutes, and then slowly cool it.

Extended data:

selection principle

On the premise of ensuring the safe and feasible use of the welded structure, the selection of covered electrode should be based on the chemical composition, mechanical properties, plate thickness and joint form of the welded material, the characteristics of the welded structure, stress state, the requirements of the structural use conditions on the weld performance, welding construction conditions and technical and economic benefits. Covered electrode should be selected pertinently, and weldability test should be conducted if necessary.
