Machine for the measurement of a large amount of spot welds at once, for the use on the production line

(based on ultrasonic transmission and reflection in dry contact and intended for a very thin steel sheets)

The device should control the quality of spot welds on thin steel sheets (0.4mm thickness) on the production line of steel containments. The welds are tested in transmission and reflection with dry contact. All 60 spot welds are tested at once in few seconds. The device is fully designed and build by Optel and contains:

• Measuring stand with ultrasonic heads with 1344 transducers;
• Send&receive multiplexer with 1344 channels;
• Conveyor for transport of measured elements;
• Electronics for control and data analysis (OPCARD).
• Software for weld quality evaluation.
