Application and prospect of NDT technology for composite mat

with reference to foreign advanced technology, the domestic testing level has been improved, The level of NDT technology for domestic aerospace composite materials has been greatly improved....

Non-destructive testing - winding method and cross yoke meth

The method of crossing the yoke must use a moving magnetized workpiece to apply a magnetic suspension while moving the yoke....

Weld X-ray film inspection imaging process-two

After a weld is welded, the appearance quality can be observed and measured. However, the internal weld of the weld can be found by radiographic inspection, such as: porosity, inclusions, cracks, unfused and other defects....

Typical magnetization method for welded joints-yoke method a

The magnetization method uses a fixed electromagnetic yoke with two magnetic poles to clamp the parts for overall magnetization, or a portable electromagnetic yoke with two magnetic poles contacting the workpiece surface for local magnetization....

Precautions for non-destructive testing of ships - problems

Non-destructive testing personnel shall perform X-ray shooting of the weld according to the number of films taken by the on-site surveyor and the position of the film....

Non-destructive testing - Magnetization method

Magnetization is divided into two directions: longitudinal magnetization, circumferential magnetization, and composite magnetization....

Non-destructive testing - types of external magnetic fields

Magnetizing a workpiece that requires magnetization in a coil or magnetizing a large workpiece around a cable, often referred to as a coil method...

What are the needs of the ship for non-destructive testing

NDT technology has a wide range of applications in the design, production, use and repair of ships. Special NDT technology is an important guarantee for the quality of shipbuilding....

Non-destructive testing - magnetic fields and magnetic lines

The magnetic field is characterized by the action of the moving charge (or current). The magnitude, direction and distribution of the electric field magnetic field are also generated while the magnetic field changes, and can be represented by magnetic...

Magnetic particle nondestructive testing

Leakage magnetic field flaw detection is a method in which a ferromagnetic material or a workpiece is magnetized, and a discontinuity exists on the surface and the near surface, and a detectable leakage magnetic field is formed for flaw detection....
