The main advantages of the UT method include, in addition to its non-destructive quality, high throughput, high reliability of detection, and full documentation capability. The UT method has been adopted in the car industry as the most appropriate method for spot weld inspection, both in the production line and in the lab. The advent of digital ultrasonic instruments provided the possibility of computer-assisted decision-making with online UT signal analysis. These factors made the method difficult to interpret, unreliable and impractical. When using such instruments, operators had to visually examine each signal and make decisions on a complex screen display. The UT method was developed in the early 1960s, using analog instruments. The total length of the echo sequence from its total thickness, together with the signal attenuation (rate of decay or amplitude drop) and the amplitude and position of the intermediate echoes differentiates between good spot welds and defective ones. The ultrasonic method for spot weld testing is based on the detection of multiple reflections from the backwall of the welded structure, together with intermediate echoes generated by the interface between plates or by flaws in the nugget. Hundreds of these Spot Weld testing instruments are currently being used by car manufacturers, whose feedback is a valuable source for continued enhancement of equipment performance. This is where ScanMaster’s Spot Weld testing instruments come in.ĭeveloped through close coordination with the automotive industry, ScanMaster’s Spot Weld ultrasonic testing instruments have set new standards in the field, significantly reducing inspection time while delivering a quick return on investment. Detecting and addressing issues before they become critical helps efficiently maintain optimum welding conditions by preventing faulty weld batches and production line interruptions. Highly effective ultrasonic inspection methods not only meet these requirements, but also detect symptoms of a deteriorating welding process, providing quasi-real-time feedback for immediate corrective actions. To remain competitive, the automotive industry requires a spot weld testing solution that facilitates increased production volumes while maintaining the highest quality standards. The average car contains several thousand spot welds that are essential to its structural integrity.

Spot welding is used for fabrication of numerous metal sheet products, such as automotive bodies, appliances, enclosures, and furniture. Since separate fasteners are not required for this process, fabrication is economical and fast.
The principal use of resistance spot welding is to join overlapping sheets of metal when the joint does not need to be gas-tight or liquid-tight.
