Description and Applications

This type is used for 550N/mm2 class high tensile steel. It shows extremely excellent crack resistance as used in all positions. It is suitable for welding of heavy high tensile steel plates, bridges, pressure vessels, steel structures, and machinery.

 
Guideline in Usage
1.

Electrodes should be re-dried at 350400 ℃ for one hour before use.

2. Keep the arc as short as possible. Use back step method to prevent blowholes
3. Preheat temperature varies in accordance with plate thickness and steels. Preheat at 70120 ℃ before welding
4. Welding with an excessive heat input, e.g. more than 55 KJ/cm for a 35 mm thick plate should be avoided to assure the strength and toughness of the weld metal
