Force tester puts welds on the spot
A novel clamping force tester can be integrated with electrode cap machining and weld current checking to provide an efficient service station to optimise welding performance and maintenance.
To meet the need for a simple to install and operate method of testing spot welding equipment, Kistler has introduced a clamping force tester that can be integrated with electrode cap machining and weld current checking to provide an efficient service station to optimise performance and maintenance The key to the tester is the robust, long life piezoelectric force transmitter that measures clamping force accurately and reliably at minimum electrode spacing

Sensor measures mould cavity pressure indirectly
Cavity pressure is usually measured with the sensor fitted directly in the mould cavity, but Kistler's new PinSens force sensor type 9204 is ideal for indirect cavity pressure measurement
Damping elements in the transmitter mountings balance out variations in the positioning and impact of the welding tongs.
Spot welding, applied to both manual and robotic production methods, is a reliable and cost-effective method of joining sheet metal components, provided all the operating parameters are maintained within specification.
Electrode cap shape, welding current and clamping force are interdependent and require regular monitoring, if weld quality and productivity are not to be jeopardised.
The Kistler spot welding force tester is an effective method of checking manual and robotic welding systems allowing potential malfunctions to be detected and maintenance to be targeted to reduce operating costs, minimise rework and enhance productivity.
