金刚石锯片的焊缝检测方法研究
Research on seam detection of diamond saw blades
摘要
Abstract
X-ray testing and eddy current testing were used to detect the seam between diamond blades and matrix of cutting tools.Then using a set of diamond saw blades weld defect detection system,weld defect location and size were acquired,stored and analyzed in order to assess the merits of the two kinds of detection methods.In the final,the location and form of the flaw by detection could be used to evaluate weld quality and performance of the diamond saw blades.The experiment results could provide a strong support for process and production of diamond saw blades.Through X-ray testing,it was found that the main flaws in weld zone between diamond saw blades and matrix of the cutting tools were crack,incomplete fusion,lack of fusion and pore.Through eddy current testing,it was known that the relationship between the defect size and voltage amplitude was linear,the detection sensitivity of which was high with reliable results.关键词
