Jani Niskanen, Project Engineer Joining Technologies, Valmet Automotive, explained:

“Valmet Automotive is capable of producing premium quality vehicles, highly efficient and exceptionally fast. To do this we need reliable and cost-effective equipment that integrates perfectly into our production lines to guarantee an irreproachable weld quality. That is why we have chosen ARO, and the feedback has been extremely positive. ARO equipment provides us with several practical advantages. The compact design of the gun body makes 3D simulations and modelling easier. In production, the 3G guns are robust and reliable, ensuring excellent productivity and availability. The use of ARO Adaptive Controllers, which automatically compensate for process variations, gives us a very good weld quality on the modern high-strength steels we use. Low diversity of components in 3G guns is also an advantage in terms of maintenance and stock management. Finally, as the 3G guns are flexible and adaptable, we have been able to re-use some of them from one project to another, which is, in my view, is a major advantage”.

The Valmet Automotive plant is also equipped with ARONET supervision software, which networks the weld controllers for efficient and centralized processing of welding data.
