Fluorescent flaw Detection machine copper NET mat

Abstract: Sheyang county Tengda flaw Detection machine factory to provide customers with fluorescent flaw detection machine copper mat suppliers, manufacturers, prices, which home good, equipment, products are sold to Jiangsu, Shanghai, Yancheng, Kunshan, Beijing, Yingkou, Dandong and other regions.

Product Details

Fluorescent flaw Detection machine copper NET matApplicable to mechanical, automotive, military, aerospace, internal combustion engines, railways and other industries to shafts, gears, disk sets such as iron magnetic materials made of parts of non-destructive testing. It can be found that the surface of the parts and the near-surface due to casting, forging, welding, stretching, quenching, grinding, fatigue and cracks, such as slag and so on very subtle defects.

Basic principle

The magnetic field lines in nature always maintain their continuity. When the ferromagnetic workpiece is placed in a magnetic field that is saturated, the magnetic lines are guided through the workpiece. If the magnetic field lines encounter discontinuities in the workpiece material (i.e., cracks, slag, pores, etc.), the magnetic lines will bypass these low permeability (large reluctance) areas and leak out the surface of the workpiece to form a "magnetic leakage". This creates a magnetic pole on both sides of the defect, and the magnetic powder (or magnetic suspension) is adsorbed around defects such as cracks. Can form a clearly visible line or point-like accumulation.

The alternating current has the skin effect characteristic, the magnetic field intensity which produces on the workpiece surface is higher than the internal, the surface sensitivity is high, the direct current is in the workpiece surface the magnetic field intensity and the internal equivalent, the magnetic field distribution is more uniform, may detect the surface certain depth the flaw.
