Steel Robotic Welding

Integrated transformer welding guns have revolutionised robotic assembly lines. Tens of thousands of ARO robotic guns have been supplied to the global automotive industry, where the ARO brand is synonymous with quality and innovation. Reliable and robust, ARO robotic guns are expected to weld at a high rate of production. Compact and modular, they adapt perfectly to the needs of each application. ARO robotic guns are equipped with: High performance transformers in AC or MFDC Non lubricated pneumatic or electric actuators allowing a welding force up to 1200daN electrodes Standard or special arms according to use Combined with an ARO controller, the robot guns can reach a high welding current.. Development of new steel grades is one the leading path for light weight vehicles required by OEM. The use of various steels alloys with hight strength performances is a driver for the development of reliable and performing resistance welding solutions.
