| Abstract：In allusion to the problem of low accuracy,bad real-time,complexity electric circuit of traditional spot welding current detecting meters,an idea of actualizing the real-time collection and calculation of spot welding current effective value using point-by-point algorithm is put forward.A spot welding current effective value detection system based on MSP430F149 is designed,and the real-time detection and display of spot welding current effective value and energizing cycle number are realized. |
