ARO’s Adaptive Welding technology responds to VOLVO prototype complexities 

Whilst ARO has been providing welding equipment to VOLVO Cars’ (VCC) plants worldwide for over 20 years, it is its Adaptive Welding (AW) technology that is helping the car manufacturer to take prototype production to new levels.

With safety being one of VCC’s core values, the company produces Body in White prototypes of different models at its Pilot Plant before crash testing them to assess the safety of each vehicle and its welded parts.

Due to the diversity of the parts to be welded and potential changes to vehicle design and materials, the Pilot Plant mainly uses manual welding equipment. By using ARO welding guns and Welding Controllers with the Real Time Adaptive Algorithm, the Pilot Plant is able to weld very strong joints at a high quality to maximize vehicle safety.

In addition, ARO’s AW technology helps the Pilot Plant to respond effectively to the continuous complexities of prototype welding by adapting to changes in material and to the presence of resistive materials such as glue, it also automatically compensates for electrode wear and shunt effect.


In manual welding, the risk of operator error is also eliminated, as only one program is necessary for all sheet combinations. Since being installed in the Volvo Pilot Plant in 2012, the AW technology has helped produce prototypes of the XC90 and XC60 models, and is now ready to undertake its next project.

With ARO’s AW system already proving its ability to adapt to the challenges of prototype welding whilst delivering exceptional weld quality, VOLVO can be rest assured that its future prototype production is safe in ARO’s hands.
