Vietz is one of the leading German manufacturers of welding and power generators for pipeline construction. Our devices are designed for use by pipeline companies, public utilities or municipal undertakings. We also supply versions for use on pipeline construction sites under difficult climatic conditions.
We have extensive experience with devices specially designed around customer requirements.
The internal combustion engines we use are of the latest generation and comply with the applicable exhaust emission standards. The machines are equipped with an automatic idling system that throttles the speed of the engine when no power is drawn. This reduces exhaust fumes, noise and fuel consumption.
All units are available with and without running gear. For mobile versions we offer configurations with rigid or height-adjustable drawbars. Steelwork and chassis are galvanised as standard on our units.


In our DGV product range we use modern welding inverters supplied with electrical power by a brushless three-phase generator. The product range includes our current models DGV 280K with one and DGV 310K with up to two welding inverters. Additional sockets supply electrical energy for auxiliary processes.
Our Arcobil product family supplements the potential of the DGV units with a compressor that provides 8 bar of compressed air on site.


With our GDV 350 K welding unit we rely on the proven and robust technology of the welding generator. The machine also generates alternating current via a synchronous generator, e.g. for hand-held machines or lighting.
The welding equipment of our welding units is 100 % suitable for vertical-down welding. All units can be expanded with extensive additional equipment such as checker plate covers, storage compartments, lighting masts or hose reels.
