Electric-arc joining
The APN1 – an adaptive platform for seam tracking
The APN1 was developed for seam-tracked welding or brazing, with a filler wire or fixed guide tip.
APN1 torch connections are available for the standard brands and electric-arc methods. Based on your process, the mechanical seam tracking is implemented with either a fixed guide tip or a filler wire.
The filler wire or guide tip is pressed in the weld joint using force control. It is then mechanically guided along the path of the joint. The APN1 compensates automatically for any deviations in the path of the joint from the programmed path of the robot. This is done laterally by swivelling on a rotary axis, and vertically by correcting the position of the torch along the linear axis.
The optimal process parameters are always in use, because the system is capable of precisely recognising the processing point. This guarantees an accelerated welding speed, an optimised heat input, and uniform seam quality.
