Dual ServoWeld™ Orientating Spin Welder

Dukane's Dual ServoWeld™ Spin Welder is designed for welding circular parts that have a tight tolerance requirement for both the orientation between the parts being welded and the overall final welded assembly height. The new design builds on the solid foundation of Dukane's existing single servo-spin welder, by replacing the pneumatic Z-axis drive with a second servomotor. The spin welders control system provides the ability to hold orientation tolerances of +/- 0.1 degree of rotation and Z-axis tolerances of 10 microns. In addition, the control system coordinates the performance of both servomotors thereby providing the user with a new welding technology Dukane calls Melt-Match. The Melt-Match technology uses a constant torque welding mode which provides the user with the ability to specify a torque value that most closely matches the melt flow rate of the material, and the controls system coordinates the Z-axis velocity and RPM to provide this torque throughout the weld cycle.

A user friendly color touch screen operator interface is standard. Setup of machine is virtually effortless thanks to the position jog teach feature. This intuitive interface allows the operator to quickly and simply jog the unit to both the final orientation axis position and the final Z-axis height position. Error conditions are graphically indicated on the panel and include an explanation of the source of the error.

All machine setup parameters are programmed through the password protected interface. This insures that no unauthorized adjustment of the machine setup can occur. A programmable feature also allows the user to define the "home" position, thereby allowing the elimination of unnecessary vertical stroke and thereby reducing overall cycle time. The machine can store up to eight setup files in local memory, and has programmable limits on up to 11 independent process parameters. All weld data can be exported via RS-232 data port.
