Instructions | ||||||||||
1.The Electrodes must be baked under 350°C~380°C for an hour before Welding and used as soon as baking is completed. | ||||||||||
2.The stains on the weldments, such as rust, oil stains, moisture, etc., must be cleared away before Welding. | ||||||||||
3.When Welding, short arc must be used and stringer bead is suitable. | ||||||||||
Application | ||||||||||
Suitable for welding important structures made by 15CrMo steel, which work temperature below 520°C, such as boiler pipes, high pressure vessels, petroleum thermal cracking equirment, etc. Also it could weld cast steel of 30CrMnSi. |
