METHODS FOR MODIFYING FINISHED MACHINE COMPONENT FORGINGS FOR ULTRASONIC INSPECTION COVERAGE

摘要

#CMT# #/CMT# 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). #CMT#USE : #/CMT# Method for modification of a forging for a finished machine component for the ultrasonic testing. #CMT#ADVANTAGE : #/CMT# The additional material in the size of the dead zone of a sensor is added to a testing surface, when the forging can be ultrasonically tested not from two surfaces opposite to each other. The additional material is added to the processing addition in the size of a sensor footprint plus the margin radius in a direction rectangular to the forging direction, thus ensures improved design of the forging mold thus enabling improved scanning during ultrasonic testing. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flowchart of the method for the improvement of scanning during the ultrasonic testing.
