Method for checking quality of accomplished joining processes of workpieces, involves detecting continuous process data automatically during joining processes, and representing continuous process data in control chart
摘要
<p>The method involves detecting continuous process data (PD) automatically during the joining processes, and representing the continuous process data in a control chart (R1). The continuous process data is compared with predetermined setpoint values (S) during the dynamic checking. A time course of the process data is compared with time course of the setpoint values in the dynamic checking. A current-time course or a resistance-time course is detected as continuous process data during spot welding.</p>
