1. Ultrasonic testing
Ultrasonic testing is a commonly used nondestructive testing method, suitable for detecting internal defects of stainless steel plates. The principle of ultrasonic testing is to use the speed and intensity of ultrasonic waves propagating in the material to detect the internal structure and defects. This method can detect defects such as holes and cracks in stainless steel plates and can determine their position, size, and direction.
2. Eddy's current testing
Eddy current testing is a nondestructive testing method suitable for surface defects. The principle of eddy current testing is to use eddy currents to generate magnetic field changes to detect surface defects of materials. This method can detect defects such as cracks and fatigue damage on the surface of stainless steel plates and can determine their position, shape, and size.
3. X-ray testing
X-ray testing is a nondestructive testing method suitable for internal structural defects. The principle of X-ray testing is to use the penetration ability of X-rays in objects to detect the internal structure and defects of materials. This method can detect defects such as holes and cracks in stainless steel plates and can determine their position, shape, and size.
4. Magnetic particle testing
Magnetic particle testing is a nondestructive testing method suitable for surface and near-surface defects. The principle of magnetic particle testing is that under the action of a magnetic field, the magnetic poles of the defective surface of the magnetic material will reverse, and the magnetic powder particles adsorbed on the surface will form a line or point that exposes the magnetic poles, so as to detect surface or near-surface cracks, flaws and other defects. This method is suitable for the detection of defects such as slight cracks and peeling on the surface of stainless steel plates.
