We planned the new manufacturing line of conditioning and inspecting of steel rod in 1983.At that time, more correct and rapid judgement on results of ULTRA-SONIC TESTING on manufacturing line has been required to meet the increase of production. So, we developed “ULTRA-SONIC SIGNAL PROCESSING SYSTEM” using 16 bit micro-computer in 1984.This system has following functions.(1) The conditions of testing and standards of judgement exist in computer files and are updated interactively.(2) The conditions of testing are set automatically to ULTRA-SONIC TESTER.(3) This system displays the distribution of flaws and automatically marks the position of the flaws on the material by paint and furthermore notes the treatement following manufacturing process by comparing standards of judgement and echo signal intensity from ULTRA-SONIC TESTER.(4) This system supervises to find something unusual in testing B-echo signal.This paper introduces the outline of the “ULTRA-SONIC SIGNAL PROCESSING SYSTEM” in Chita Plant.
