为了无损检测金属胶接结构的胶接强度.我组在六二五所、七二一厂、武汉无线电元件厂的大力协助下,参考国内外有关仪器于一九六六年十二月研制成松花江-Ⅸ型胶接质量检查仪(图1)。松花江-Ⅸ型胶接质量检查仪是一种按“换能器谐振法”进行工作的超声波探伤设备。“换能器谐振法”是资本土义国家探伤的主要办法。一九五一年荷兰 Fokker(弗克)皇家飞机工厂在美国麻省工学院 H.G.Albert
In order to non-destructively test the adhesive strength of the metal cementing structure, with the great help of 625, 721 and Wuhan Radio Components Factory, our group made reference to relevant domestic and foreign instruments and developed it in December 1966 Songhua River-IX type glue quality tester (Figure 1). Songhua River-type IX glue quality tester is a press “transducer resonance method” to work ultrasonic testing equipment. “Transducer Resonance Method” is the main method of flaw detection in capitalist countries. 1951 Dutch Fokker Royal Aircraft Factory at the Massachusetts Institute of Technology H.G.
