X-Ray radiographic inspection : Grade II
Notice:
1. If the electrodes are affected with damp, they must be baked under 80ºC for 1.5 hours before welding.
2. The stains on the weldments, such as oil stains, rust, moisture etc., must be cleared away before welding.
3.The electrode weaving should not be too wide and the strength of the arc should be suitable.
