Research on Metal Magnetic Memory Based Welding Seam Detection of Hydraulic Support

In allusion to techniqut defect of hydraulic support detection,this paper brings forward a method of metal magnetic memory based detecting technique for hydraulic support seam.This equipment is composed of magnetoresistance sensor,the module for blowing up signal and communication,MPU,the software of detection system.This paper introduces hardware design,includes buildup of mostly modules,and special design for dependablilty.The experiment validates,by way of metal magnetic memory,it can measure quality of welding seam availability.This method is stabilizaly and credibility.
