Method Of Hexagon Socket Head Bolt Detection

  •    What are the detection methods of Hexagon Socket Head Bolt? Bolt detection is divided into two types: manual and machine. Manual is the most primitive and most commonly used consistent detection method. In order to minimize the outflow of defective products, the general production company personnel inspect the packaged or shipped products by visual inspection to eliminate defective products (defects include tooth injuries, mixing, rust, etc.).

       Another way is automatic machine inspection, mainly magnetic particle inspection. Magnetic particle inspection uses the interaction between the leakage magnetic field at the bolt defect and the magnetic powder to deal with the difference between the magnetic permeability of the bolts (such as cracks, slag inclusions, mixing, etc.) and the permeability of steel. These materials are discontinuous after magnetization. The magnetic field at the location will be turbulent, forming part of the magnetic flux leakage, and a leakage magnetic field will be generated on the surface of the workpiece, thereby attracting the accumulation of magnetic powder at the defect where the magnetic powder is formed-magnetic mark. China Stud Supplier shows the defect location and The shape, observation and explanation of the accumulation of these magnetic powders, has achieved the purpose of rejecting defective products.
