1.前言1967年京浜制铁所在日本首次使用脉冲反射式探伤仪。自那时起,该公司就开始了厚板自动超声波探伤仪的开发。此后便致力于这一方式的改进,1970年京浜制铁所又增设了许多具有新功能的装置,确立了脉冲反射方式在厚板超声波探伤中的地位。1978年到1982年,新生扇岛厂引进了新技术,使用计算机进行缺陷长度评价处理,从而完成了第二代探伤仪的开发。这次福山厂借更新探伤仪之机,在重新全面认识其性能的同时,开发了一种完全自动探伤的世界最新自动超
1. Foreword In 1967, Keihin Iron & Steel Co., Ltd. used the first pulse reflection flaw detector in Japan. Since then, the company has started the development of slab automated ultrasonic flaw detectors. Since then, he has devoted himself to the improvement of this method. In 1970, the Beijing Iron and Steel Institute added a number of new devices and established the status of the pulse reflection method in the ultrasonic flaw detection of thick slabs. From 1978 to 1982, the new fan island factory introduced new technology, the use of computer defect length evaluation process, thus completing the second generation of flaw detector development. The Fukuyama plant by updating the machine flaw detector, in full re-understanding of its performance at the same time, developed a fully automatic detection of the world’s latest automatic ultra
