Radiographic inspection is mainly used in the shipbuilding industry to detect internal defects in welds, castings, and pressure vessels, ensuring the safety and reliability of ship structures. Specific application directions include:

1. Ship weld inspection: Through X-ray radiography, defects such as porosity, slag inclusion, and cracks in the weld are detected to prevent safety accidents caused by welding quality issues. For example, in the construction of the Type 076 amphibious assault ship, the welding qualification rate is as high as 99.97%, and non-destructive testing has exceeded 120000 times.

2. Casting inspection: Detect defects such as pores and inclusions inside the casting to ensure its reliability.

3. Pressure vessel inspection: Regularly inspect pressure vessels in ships to ensure their safety during operation.
