1. thereby one kind is used ultrasound wave to come parts are carried out the method that nondestructive measurement and effectiveness are estimated by the rotation between measuring head and parts or translation relative motion in reflection or transmission beam method, be particularly useful for testing the joint of insert casting component in the rotation parts, for example, test is used for the piston of internal combustion engine and other piston type transmitterDescribed method is characterised in thatAccording to the following step the amplitude function AF1 (i) that depends on the position and/or depend on angle that infers with measured value AF (1...n) in measuring process is determined to handle, residing position when wherein this value is measured in AF typical value itself and i=1...n representative, described step is:

  • A. in first time correcting process, in order to shield or the measured value of one or more mask tapes of interpolation parts, infer out the amplitude function AFk1 (i) that revises through once, wherein surperficial inhomogeneity having occurred at the place, one or more mask tape of described parts has especially occurred discontinuous, each mask tape is to be defined by the primary importance value-initial numerical value u1 of described band and the ending numerical value u2 of second place value-correspondence thus
