本文介绍金属超声波探伤用标准人工伤的制作及测量。标准人工伤的制作,以往大部分采用机械加工、手工刻制的方法,或者选用金属表面的自然缺陷。标准人工伤的测量,采用千分表直接测量,及胶体模压法的间接测量。利用这些方法制作及测量的标准人工伤,在正确性、可靠性、重复性等方面都不能确保超声波探伤的需要。在无产阶级文化大革命的推动下,我国社会主义革命和社会主义建设形势大好,新技术、新工艺、新方法,在工业生产中被广泛应用,取得了可喜的成果。电火花加工和显微测量技术,被应用于超声波探伤,用它来加工及测量标准人工伤,是一项较为先进的方法,深 This article describes the manufacture and measurement of standard artificial wounds for metal ultrasonic flaw detection. The standard artificial injury, the past, most of the use of mechanical processing, hand-carved method, or the use of natural defects on the metal surface. Standard artificial injury measurement, direct measurement using a dial gauge, and indirect colloidal molding method. Standard artificial injuries made and measured using these methods do not ensure the need for ultrasonic flaw detection in terms of accuracy, reliability, reproducibility, and the like. Under the impetus of the great proletarian cultural revolution, the socialist revolution and socialist construction in our country have enjoyed a fantastic development. New technologies, new techniques and new methods have been widely applied in industrial production and have achieved gratifying results. EDM and microscopic measurement techniques, is used in ultrasonic testing, use it to process and measure the standard artificial injury, is a more advanced method, deep
