With increasing requirements on the material characteristics – in particular in aviation and automotive industries – automated testing has to meet increasing standards. In consequence, existing testing machines might reach a premature end of their life-cycle, unless they receive substantial upgrades. Herein we present a new evolution stage for the ultrasonic phased array testing machines of the established the ROWA platform. This upgrade provides improved testing speeds, extended calibration functionality, and, moreover, the ability for testing of new profiles.
Round and hexagonal bars are the most frequent semi-finished products in steel industry. Since these geometries share common dimension ranges, many plants run production lines for both geometries and, accordingly, aim for a unification of the inspection lines. However, the inspection procedures of round and hexagonal bars are fundamentally different as the edges of the latter are exposed to higher stress in the finished product. Therefor a full-body test needs to be complemented by a surface inspection with a high coverage towards the edges. Note, it is essential that the operational capacity is not adversely affected.
To achieve this, the ultrasonic field and evaluation gates will be adapted to the actual geometry of the specimen, while maintaining the testing resolution and feed rates of up to 1.5m/s. The modular concept offers full flexibility regarding dimension changes at short changeover times.
