摘要

The effect of exerted pressure of the buffer rod on the sensitivity of ultrasonic testing of hot steel blooms by the pressure contact method is discussed. The formula describing their linear relation is introduced. Results show that, at a given temperature, sensitivity increases linearly with pressure until a certain pressure is reached where sensitivity is rather insensitive to pressure variations. However, this pressure region is not always used. The proper choice of exerted pressure for practical use is analyzed.
