Safety parts within the automotive industry, such as the treated transmission element of the steering mechanism, are subject to the most severe conditions and controls within the production process.
To meet these conditions, the nondestructive ultrasonic inspection for the detection of flaws due to the die-forming has been envisaged among other methods.
Typical flaws include overfoldings and cracks which are only seldom visually recognizable on the surface.
The recommended immersion test arrangement is outlined in the figure:
Because of the defined flaw area, scanning in a fixed probe position is sufficient for the flaw detection using the H5K probe's large sound beam which is additionally expanded by being reflected from the curved backwall.
The component analysis is carried out by evaluating the flaw indications between the interface echo at sound entry and the indications from the geometry, such as edges – openings – holes.
