This document introduces A-type ultrasonic pulse contact method that applies ultrasonic longitudinal wave technique to hardmetals.
This document is applicable to the ultrasonic inspection for a hardmetal rod that has a circular end face with a diameter not less than 6,0 mm and a rod length of 40,0 mm to 380,0 mm, or a hardmetal product that has a non-circular testing area not smaller than the coverage area of probe (recommend not less than 12,0 mm in diameter) and a height of 10,0 mm to 380,0 mm.
Within the detection range specified in this standard, the sound transmission energy is expressed by the probe driving voltage, and the range is 100,0 V to 200,0 V.
