Pioneers of modern welding technology

Messrs. Carl Cloos Schweisstechnik GmbH in Haiger, are one of the pioneers of modern welding technology and are still today one of the international market leaders. They have united two core businesses, arc welding and robot technology, under one roof and can offer customers economic and technically high-quality solutions from a single source.

High-capacity range of products

About 700 employees develop and manufacture the CLOOS product range – from QINEO® welding machines up to turnkey QIROX® robot systems and automated special purpose equipment supplied specifically for customers’ individual requirements. The highly efficient product range of MIG/MAG and TIG welding machines and the robot system technology can be found in complex production lines and cost-effective compact welding cells used in the core markets automotive, commercial vehicle and mechanical engineering.

Future-oriented solutions

With a large range of proven and innovative welding processes, CLOOS can offer solutions for the future providing maximum efficiency and productivity with regard to automated welding. Products and processes are tested at the technology centre under practical conditions. All necessary processes meet the quality management system DIN EN ISO 9001.

Cloos Welding robots at the top of the international class
As one of the leading specialists in the development and manufacturing of high-value welding robots for demanding industrial applications, CLOOS uses its decades-old know-how for continuous development. Thanks to the integration of innovative technologies, the new generation of QIROX® welding robots offers additional customer value and production advantages. Among the particular highlights are the complete revision of the product design and the introduction of an optional seventh axis. Both innovations contribute to a considerable increase in the flexibility and dynamics of the QIROX® welding robot. As a result, the automated welding processes can be configured in a clearly more efficient manner. 

Custom and Pre-Engineered Robot System

  • Custom engineered robot systems are designed with the customers' specific configuration needs and requirements in mind or choose from the space-saving compact design of a pre-engineered robot - the economic way to weld.


  • The QIROX® robot line offers the highest flexibility with the new modular design and optional seventh axis.

Welding Equipment 

  • This CLOOS line of welding power sources offers solutions for every manual or automated welding application.

QIROX® Positioners

  • Always in perfect position; solutions for every component.Perfect synchronisation of all welding robot axes with the positioner.
  • Increased profitability through high production speed, utilisation of several workstations and long welding lines without interruption.
  • More flexibility through increased operation range of the robot and additional animation constructions.
  • Easy processing of components with large volume.
  • Matching operating system makes programming easy and allows for short changeover time.

Speed Weld - Special process for high-speed welding

The Speed Weld process is most suitable for joining components of thin to thick wall thicknesses. Good penetration depths and perfect side wall joints at high weld speeds are achieved by means of a focused pulsed arc with a scalable deposition rate. The Speed Weld process is used in all industrial production sectors.

Control Weld - Controlled thin plate welding

The Control Weld process supplies a uniform arc which is particularly advantageous when welding thin steel. The classic industries are automotive construction, electronics, vehicle construction, heating technology, white goods and furniture. This process can also be used for reliable repair welding throughout all industry sectors and allows for welding under pure CO2.

Cold Weld - Welding with minimum heat input

By using a negative phase, targeted heat-placing control is possible during the Cold Weld process which allows a very low heat input. This "cold" arc welding allows optimum control of the welding process. The thermal loading of base material is reduced and the origin material characteristics remain nearly unchanged. Thus a high weld seam quality at a good gap briding ability and increased weld speed can be achieved. The Cold Weld process is mainly used for thin to medium plate thicknesses.

Tandem Weld - The process for more productivity 

Two in-line wire are fed simultaneously and melted in two arcs. Due to the consequent separation of the two electrical cicuits the arc can be controlled in detail. Enormous efficiency, low heat input, excellent weld seam quality and the very high deposition rate are the great advantages of the Tandem Weld process.

Laser Hybrid Weld - As efficient as never before

Compared to traditional Tandem and MAG welding, considerable savings in production time and filler material are possible. Single pass weld seams can be welded without preparation even in the case of thick plate with material thicknesses of more than 10 mm. Moreover a high weld speed can be reached even when welding thin plate. It is not only the automotive industry that demands high-quality weld seams: due to the minimum rework required, the MIG/MAG Laser hybrid welding process is also of interest to companies manufacturing components for commercial vehicles, railway carriages and construction machinery.

Duo Pulse - Alternating arc weld for rippled weld seam surface

The Duo Pulse process creates outstanding weld surfaces and ensures a reliable weld seam quality. The change of heat input in the arc results in a uniformly rippled weld seam surface which means that rework on visible welds is minimised. The furniture and electrical industrial sectors, and aviation, automotive and motorcycle industries are all suitable application areas.
