Description

Technical Field

[0002] Before a boiler is put into operation, it is necessary to use appropriate inspection equipment and methods to inspect the welds to ensure the quality of the welding and prevent potential safety hazards caused by the welds during boiler operation. Currently, the most common method for inspecting welds is using X-ray inspection equipment.
