The aim is to discuss the ultrasound technique applied to the inspection of resistance spot welding, and to demonstrate the advantages of this technique over the conventionally standardized destructive tests. For this, two experimental procedures were organized, the first using the a‐scan (single element transducer) ultrasound technique, in which the effects of the indentation of the spot weld were studied, one of the parameters that can be easily detected by this technique. The second experiment seeks to demonstrate the detection capacity of the ultrasonic b‐scan technique (matrix transducer), in which the methodology was applied to seek the correlation between the results obtained by the equipment with the results found in the peel test and also in the macrographic results conventionally known. With these experiments, it was possible to prove the reliability and reproducibility of this technique, showing an increase in precision when related to the normalized known tests, besides the quantitative evaluation that can be made, allowing the statistical collection of data.
