Innovative welding and handling technology

The Viessmann Group relies on innovative production technologies worldwide. At its Berlin site, a new robot system by CLOOS not only carries out welding, it also handles the boilers. This enables Viessmann to reduce set-up and cycle times to a minimum and to make the entire production process more flexible.

Founded in 1917, Viessmann is a family company that employs around 11,600 people worldwide. With 22 production companies in 11 countries, sales and service facilities in 74 countries and 120 sales offices worldwide, the company is one of the leading international manufacturers of heating, industrial and cooling systems. At its production site in Berlin, where heat generators from 80 kW to 2000 kW are manufactured, around 400 employees produce more than 12,000 boilers each year. "Automation plays a key role in our production process," explains Bernhard Rothkegel who programs robot systems and automated welding machines at Viessmann. “We now have five CLOOS robot systems in operation."

Intelligent positioning system and adaptive sensor technology

The latest robot system with a QIROX QRC-350 welding robot was added in spring 2016. Its stand-out feature is its well-designed handling system — the positioner grips and clamps the boiler automatically to bring the workpiece into the optimum position for welding, loading and unloading. When one side has been fully welded, the positioner rotates the boiler automatically to weld the other side.
