In order to avoid welding deformation, the lead plate and the anti-radiation lead plate price, the factory direct welding adopts symmetrical welding (including butt welding, vertical welding, and oblique welding);

During the welding process of the lead gate, the slag is removed from the welding seam one by one, and the spatter is removed. If any defects are found, they should be polished with an angular grinding wheel to remove the defects;

After the lead gate welding work is over, clean up the welding seam area and the welding work site, and transfer to the next welding node.

The post-weld inspection method is as follows:

After the weld is cooled, the appearance of the weld is inspected;

There should be no cracks in the weld, the weld metal and the base metal are completely fused, and all the cracks are filled;

Welds should not overflow.
