<p>The present invention provides a weld control monitoring system (10) which determines the quality of the welds in real time, and provides responsive useful outputs indicating the quality of the weld. The system (10) permits the user to input weld data as well as quality specifications which the part must meet in order to continue the production run. A monitoring system can be used with or without programmable logic controllers (16) and includes special program for estimating the tip wear of the welding electrodes (34). The present invention also includes a weld gun control. Additional travel for the weld gun electrode (34) is provided by cylinder (40) adjacent rail structures (50) which permit displaceable movement of the electrode mounted to linear displacement welding cylinder (30). An LVDT sensor (35) coupled to the piston rod (32) of the weld cylinder provides linearly variable displacement transducer signals for use in monitoring portion (14) of the apparatus. The monitoring apparatus (14) also provides statistics of individual and groups of parts produced with the welding apparatus.</p> |
