Welding at WOLL
We have been certified welding specialists since our company was founded. We have grown from qualified locksmiths to experienced welding professionals who map out individual projects from the prototype stage right up to mass production. We develop bespoke specialist welding machines for our clients by integrating our experience in welding technology into our automated assembly department.
