Abstract
A welding system for real-time weld quality detection during resistance welding of a workpiece has a sensor assembly including a winding and a core mounted generally coaxially within the cylinder of the welding gun. A piston and piston rod assembly are mounted for coaxial movement within the cylinder. The piston rod has an end protruding from the cylinder for affixing an electrode thereto. Axial movement of the piston rod relative to the cylinder causes axial movement of the core relative to the winding to vary a length of core and winding overlap. The sensor assembly produces an output signal based on the length of core and winding overlap to indicate piston rod position relative to the cylinder. Weld control logic receiving the sensor assembly output controls welding of the workpiece in real-time.
