Carl Cloos Schweisstechnik

What Carl Cloos Schweisstechnik does

Carl Cloos Schweisstechnik GmbH is a German welding technology company headquartered in Haiger, founded in 1919 and operating as an independent private limited company (GmbH). The company manufactures and sells welding equipment and automation systems spanning manual welding power sources and torches, collaborative robot (cobot) welding solutions, fully automated robotic welding cells, and custom concept systems, together with digital IIoT and software products. It serves manufacturers across automotive, aerospace, construction, agricultural equipment, and general industrial segments, with cited enterprise customers including AGCO/Fendt (Industry 4.0 tractor cab production) and HUCH (automated buffer storage tank production). The company employs over 1,000 people globally, operates 16 subsidiaries and 10 production sites, and reports group revenue of approximately €230 million.

The company's technical core is the proprietary QIROX robotics platform - a modular system encompassing WeldExperT Compact Cells, QIROX RoboPlan offline programming, Quick Weld Programming (QWP), EasyWeld, and RoboScan seam detection - and the proprietary TANDEM+ 3-wire MIG/MAG high-deposition welding process. Digital offerings include the C-Gate modular IIoT platform for production transparency and process monitoring and the CLOOS QNECT connectivity solution. The company states that it maintains over 90% manufacturing depth on main components, integrating in-house development of robots, power sources, and software rather than relying on third-party robotics platforms.

The business model combines hardware sales (manual welding equipment, robotic welding cells, custom concept systems) with subscription-style recurring digital revenue (C-Gate, CLOOS QNECT, QIROX software) and a professional services layer covering consulting, maintenance, repair, spare parts, retrofitting, validation, and CLOOS Academy training. Go-to-market is exclusively direct enterprise field sales through the global subsidiary network; pricing is quote-based and not publicly disclosed. Recognition of ownership is partial - the company is described as independent with no disclosed parent, investor, or shareholder structure, which itself is a data gap.
