Abstract

This article focuses on the development and evaluation of a novel online quality inspection method for resistance spot welding (RSW) of aluminum alloys using fiber-optic sensing technology. The study establishes a strong linear correlation between changes in fiber-optic sensor signals—specifically the maximum wavelength shift related to dynamic electrode force—and the weld nugget size under varying welding currents, electrode forces, welding times, materials, and thicknesses. Additionally, the fiber-optic sensor signals effectively detect expulsion events during welding by identifying characteristic signal drops and vibrations, enabling real-time quality control. The findings demonstrate that fiber-optic sensing offers a reliable, non-destructive, and real-time approach to monitor weld size and process stability in RSW applications.
