Weld Checkers

Weld checkers, testers and weld monitors measure one or more of the electrical and/or mechanical parameters that dynamically change during the resistance welding process. These parameters include weld current, voltage drop across the electrodes, work piece expansion and deformation, electrode force, electrode displacement (movement) and more.

Resistance welding process monitors (weld checkers) measure and monitor the different variables that are simultaneously occurring during the resistance welding process. These tools help identify areas of improvement and overall process development.

Dengensha WS-100

The WS-100 monitors the secondary current and cycle time of resistance welders during the welding cycle. The results are shown on an LCD display screen which offers the choice of current measurement, waveform, history and system screens. The unit also includes a USB interface to a PC to allow easy conversion of the weld history to a .CSV file.

Dengensha WS-80

The WS-80 monitors the secondary current and cycle time of resistance welders during the welding cycle. The results are shown on a fluorescent display and can be sent to the included printer in both numeric and waveform format. The internal memory stores up to 800 data items measured consecutively. Any measurements that exceed the specified range are reported by visual alarm, buzzer sound and a relay output.

WeldComputer WeldView

The WeldView Monitor for resistance welders provides a comprehensive and cost-effective means of ensuring the integrity of every welded product. It typically performs more than a thousand separate checks on every production weld to verify the performance and repeatability of the process. During each weld, voltage, current, conductance, and power profiles are automatically monitored. Force and displacement measurement profiles are also available options to provide the most comprehensive weld quality monitoring.
