Resistance spot welding (RSW) is the leading process of automobile body welding, and its quality is related to the reliability and safety of the whole vehicle. The effectively and automatically ultrasonic nondestructive testing is the development direction which can judge the spot welding quality, and then the positioning error of probe has an important impact on the test results. From this, conventional ultrasonic A-scan is adopted. Firstly, this paper presents the nugget diameter mathematic model of two-layer plates with different thickness when the probe positioning error is present. Then, the ultrasonic nondestructive testing simulation models of the spot welds are established, and the influence of the probe positioning error on the calculation result of the nugget diameter is studied. Finally, this paper carries out ultrasonic nondestructive testing of spot welding of two-layer plates with different thickness when the probe has positioning error. The experimental results verify the correctness of the theoretical analysis and simulation.

La soldadura por puntos de resistencia es una técnica común en la industria manufacturera, especialmente en el sector automotriz en México, debido a su versatilidad y facilidad de implementación. La evaluación de la calidad de estas soldaduras es crucial, y existen múltiples métodos para ello, lo que complica la elección del más adecuado. Este artículo presenta una revisión de la literatura centrada en métodos no destructivos para la confirmación de la calidad de la soldadura por puntos de resistencia. Se destacan técnicas como la inspección por ultrasonido, la termografía infrarroja y la visión por computadora, entre otras. La metodología empleada incluye un análisis comparativo de estudios recientes para identificar las mejores prácticas y aplicaciones en la evaluación de la calidad de la soldadura por puntos. Los resultados de esta revisión proporcionan una guía comprensiva para investigadores y profesionales, facilitando la selección de métodos adecuados para aplicaciones específicas.
