Penetration testing can detect surface defects in non-magnetic materials, providing a complementary means of magnetic particle detection.

Non-destructive testing technology can ensure strict quality inspection and acceptance standards, and control road engineering quality within reasonable performance requirements to avoid excessive quality improvement of road and bridge engineering due

Eddy current testing technology for nondestructive testing. Penetration testing can detect surface defects in non-magnetic materials, providing a complementary means of magnetic particle detection

Magnetic particle detection is to magnetize (integral magnetization or local magnetization) by applying a magnetic field to the workpiece to be inspected

There are many kinds of rays, among which there are three kinds of X-rays, γ-rays and neutron rays that are easy to penetrate substances.

NDT technology are five main types of non-destructive testing: Ultrasonic Testing, Radiographic Testing, Magnetic Particle Testing, Penetrant Testing, and Eddy Testing. Current Testing).
