This paper presents a novel welding quality evaluation approach based on the analysis of electrical signals. The method has been implemented in an automatic system developed using field-programmable gate array (FPGA) acquisition boards and custom software. The system has been implemented in an industrial machine to detect faults in tinplate welding. Experimental results show that the system is characterized by high sensitivity and high speed. Furthermore, it needs simple conditioning electronics and tuning procedures. The system is suitable for network operation and remote control
