WAYS OF MODIFICATION OF FORGINGS FOR READY-MADE MACHINE PARTS TO ENSURE ULTRASONIC CONTROL COVERAGE

摘要

The method involves preparing a processing addition (101). The material in the size of twice of the wavelength of an ultrasonic testing device is added to processing addition in forging direction (103). The additional material in the size of the dead zone of a sensor is added (107) to a testing surface, when the forging can be ultrasonically tested not from two surfaces opposite to each other (105). The additional material is added to the processing addition in size of a sensor footprint plus the margin radius in a direction rectangular to the forging direction (109).
