This product will be a perfect solution to the problems that exist in the quality inspection of automotive welded joints. The product uses eddy current detection technology, through the probe in different roles of the coil to assess the quality of the current state of the welded joint. In the era of application on the welded joint detection, the welded joint detection has been raised to a new level becasue of qualitative and quantitative accuracy.Directly analyze the degree of change in the material of the welded joint after welding. False welding and sticky welding has a very high detection rate. The size of the weld core, strength and the current state of the quality of the welded joint can be analyzed in a short time.
