When the test piece is placed near a coil with alternating current

When the test piece is placed near a coil with alternating current, the alternating magnetic field entering the test piece can induce an eddy current (eddy current) flowing in the direction perpendicular to the excitation magnetic field in the test piece. A magnetic field opposite to the direction of the excitation magnetic field will be generated

Special casting with natural mineral sand and gravel as the main modeling

Casting is a process in which metal is smelted into a liquid that meets certain requirements and poured into a casting mold. After cooling, solidification and cleaning, a casting with a predetermined shape, size and performance is obtained. Because the casting blank is almost formed, it can achieve the purpose of avoiding machining or a small amount of processing, reducing the cost and reducing the time to a certain extent.

Liquid penetration testing is used to check various opening defects on the surface of castings

Liquid penetration testing is used to check various opening defects on the surface of castings, such as surface cracks, surface pinholes and other defects that are difficult to find with the naked eye. The commonly used penetrant inspection is color inspection, which is to wet or spray a colored (usually red) liquid (penetrant) with high penetrating ability on the surface of the casting.
