Welding devices hold two or more (car body) components in position so that they can then be permanently joined together. These can be, for example, a car body component and a fastener such as a weld nut. For this purpose, an electrode with ceramic centring pin is required in the device to position the weld nut relative to the hole in the sheet metal. In the ideal case, this process is monitored by additional sensor technology to ensure that no rejects are produced and to avoid complaints. The ModulMaster welding devices were developed to meet this requirement for maximum process reliability: The welding device is compatible with almost every projection-welding machine in the automotive industry and can be precisely adapted to the respective performance requirements thanks to its modular design.

Top performance in a nutshell.

More efficiency, less waste

ModulMaster by DOCERAM sets benchmarks in terms of quality, process reliability and efficiency. The new welding device is compatible with almost every projection-welding machine in the automotive industry and can be precisely adapted to the respective performance requirements thanks to its modular design. Thanks to the newly designed steel mounting and change electrode, ModulMaster also allows you to achieve extremely short retooling times.

Solutions - Welding device

Advantages:

  • Welding device with intelligent sensor technology - with innovative weld nut query before welding is performed

  • Optimum quality assurance and efficiency

  • Quick retooling without the need for laborious disassembly

  • Flexible adjustment to production requirements

The functional principle: intelligent sensor technology.

The new DOCERAMwelding devices enable reliable quality control with sensor-controlled real-time detection of the centring pin position. The sensors to be integrated for this purpose are linked via a universal interface to an existing PLC to guarantee secure connectivity.

The top model N300 is equipped with sensor-controlled detection of the pin position. The outstanding feature: It enables detection of the nuts and identifies a large number of production errors BEFORE the welding process is triggered: from inverted or incorrect nuts all the way to incorrect or missing pieces of sheet metal.

The sensor technology on the ModulMaster registers in real-time whether the centring pin is in the correct position for the respective welding process. In this way, you can enhance process reliability and quality assurance even during production and significantly reduce waste.

DOCERAM welding devices for every requirement

ModulMaster: master of modular design:

The modular concept makes ModulMaster extremely versatile. On the basis of three different cylinder housings and four connection plate types, you can realise a large number of device variants and adapt them precisely to the respective production requirements.
