Since a robot's motions and cycles are programmable, it is possible to program a "check cycle" into the welder's program

One of the major contributors to the quality of a spot weld is clamping force.

This clamping force is typically audited by a technician, making periodic measurements of the weld force using a hand held instrument.

Since the robot's motions and cycles are programmable, it is possible to program a "check cycle" into the welder's program.

At regular intervals during a typical day, weld robots are programmed to move the weld tips into a tip dresser that grinds the tips into the optimum shape.

Once this process is complete, the weld robot then is instructed to move to the Weld Robot Check Station.

Here, the weld robot momentarily clamps down on a sensor that measures clamping force.

The Weld Robot Check Station has memory on board that can hold thousands of measurements.

This provides the following benefits: A technician can easily observe trends in the clamping force and take corrective action before inferior welds are created; The Weld Robot Check Station can check each clamping force against predetermined limits and notify the manufacturer of problems immediately; The clamping force can be measured much more frequently so problems are discovered before failures occur; The robot does not need to be removed from service to make the measurement; Cost is a minimal percentage of the cost of the robot.

The manufacturer can set up the Weld Robot Check Station to hold readings until a technician can download them manually, or it can be networked such that the readings can be sent to a central computer that monitors all welders either on a line or in the plant.
