The revolutionary approach of the first pipe welding machines, whose developement had been started by Armin and Dieter Dommer in 1967, is considered to be the basic concept of practically every equipment that is available worldwide. They have been refined constantly – for workshop, construction site and special applications.
A further milestone in the development was the integration of the CNC technology in welding machines for construction sites and workshops.
