Abstract: Electrical resistance welding apparatus suitable for securing an insertable spider in the annular rim of a wheel includes a plurality of circumferentially spaced apart opposed electrodes each for forming a seam weld made up of a series of overlapping welds. Each electrode set includes an inner and outer wheel type welder head. The inner head includes a conductive shaft having a conductive sleeve rotatably mounted thereon. The sleeve carries the inner wheel electrode and is also tiltably mounted on the shaft so that weld pressure upon the inner wheel electrode tilts the sleeve against the shaft. Thereby, the weld pressure maintains good electrical contact between the shaft and sleeve, even as the sleeve rotates, to prevent arcing therebetween.
