In the manufacturing process of boiler pressure components, raw materials must undergo complex processing deformation and welding, so the steel used to manufacture the boiler must also have good process performance. All materials S355J2, S355K2 medium plates used to manufacture pressure parts must conform to the relevant national standards for boiler steel. The defects such as delamination, non-metallic inclusion, porosity and looseness in the steel shall be as few as possible, and white spots and cracks are not allowed.
Non-destructive flaw detection of steel plates is a test method for inspecting the S355J2, S355K2 medium plates surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used S355J2, S355K2 medium plates steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.
