Instructions
| ||||||||
1.The Electrodes must be baked under 300~350 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
| ||||||||
For welding low alloy CrMo pearlitic steels, such as high temperature, high presure boiler pipeline, petroleum cracking equipment, working temperature of which is below 540 ℃. | ||||||||
