FMW – Multi welding system

Our Multi welding system makes it possible to combine universal welding applications in a single system. Different welding processes are also available on an individual basis and new processes can be added as required. Our Multi welding system is the number one choice in sectors where different types of components (pipes, flanges, reducers, fittings, valves, etc.) and different metal alloys play a significant role, such as the food, plant construction, and energy technology industries.

In addition to the intuitive HMI, the Multi welding system lets you switch between welding processes in next to no time. Equipped with quick-release fasteners, welding torches can also be changed in seconds. Developing customer-specific sequence controls and programming the welding process has never been so easy, both saving time and opening up completely new possibilities.

The advantages for you

/ Modular design: Fronius put a great deal of thought into the concept behind the Multi, with its highly modular design allowing the welding system to be adapted perfectly to suit customers’ needs. Components with a diameter of up to 1,200 mm and length of up to 12 m can be welded without any difficulty.

/ Freely configurable: Choose between six different sizes to suit the dimensions of the components. A selection of rotating units and manipulators makes every system an individual customer solution.

/ Wide range of welding processes: Depending on the application, you can also choose from a range of suitable welding processes (TIG cold wire, TIG hot wire, ArcTig, plasma, MIG/MAG, CMT, etc.).
