Sensor assisted (remote) welding processes

Abstract

Remote welding is widely used in automotive applications like car seats or doors. This technology is able to increase productivity and quality while reducing cost and weight of the parts.Using pathfinding and detection of the position of the welding sample in a remote welding system flange size can be reduced even more. With this technology a fillet weld which requires much higher positioning accuracy than overlap weld is possible. The pathfinding and position detection systems are directly connected to the scanner control unit and therefore the correction of the geometry can be done online in real time. Moreover the gap size can be measured and with this information the user can actively adjust to the new welding situation and prevent a fault. In addition new welding applications with this novel sensor system are shown, e.g. door welding with reduced flange and fillet weldRemote welding is widely used in automotive applications like car seats or doors.
