Water-cooled orbital welding heads are designed for use under high thermal loads. The components that are primarily responsible for introducing heat into the system are cooled with a high water flow rate. The water-cooled orbital welding heads are universal and ideal for small spaces thanks to the slender design.
At Orbitec, the drive unit, hose package, and welding head are designed in a modular way. This allows various cassette welding heads to be operated with the same drive unit (except for the microfitting welding head). The result: reduced investment costs and greater flexibility in welding applications.
Universally applicable - thanks to its slim design, ideally suited for confined spaces. Our new generation of compact weld heads for high thermal capacities with a water-cooled collet housing and clamping levers. Both CW heads are operated using one handle and cable assembly.

Our new generation of three OSK SW weld heads – even narrower, technically optimised and redesigned. For very high thermal capacities, we also offer the gascooled S series weld heads in a water-cooled SW version (the structural width stays the same). The closed water cooling system covers the bottom collet housing area.

The following components are required to operate an OSK weld head. The drive unit houses the motor and the start-stop function for the weld head. Suitable clamping jaws ensure secure fixation and are selected according to the respective tube diameter.
Consisting of a handle with control element (start/stop button and status display), weld head interface, motor / gearbox unit and 8 m hose package.
Handle and cable assemblies consisting of a handle with control element (start/stop button and status display), weld head interface, motor /gearbox unit and 8 m hose package. The OSK GW and SW handle and cable assemblies and weld heads are compatible with one another!
We have a comprehensive range of collets in stock for all OSK heads. 1 set per tube outer diameter = 4 half-shells. All collet Ø in stock can be found in the table on page 66. Other Ø and collets with a common contact surface are available as custom designs on request.

SuperArc: Precision-machined disposable tungsten electrodes for reproducible orbital welding. Cut your costs, because each new manual sharpening operation costs time and money. Standard quality WC 20 to DIN EN ISO 6848.
Finished dimensions for all ORBITEC weld heads as a function of the tube outer diameter.
As a one-stop supplier for orbital welding, we also offer a wide range of accessories. Electrode holders and gas shield collets are available for the orbital welding heads. These are used to weld fittings, flanges and components with short welded sockets.

GAS-shield collets are particularly narrow and have an aluminium base collet and a screw-on gas-shield collet made of heat-resistant GRP material. They are used to weld fittings, flanges and components with short welded hexagon nipples. In conjunction with offset or multi-position electrode holders, the weld can be completed very close to one side of the weld head. A collet set with a common contact surface is recommended for secure fixing. GAS-SHIELD collets are available for OSK 53 / 76 / 115 weld heads (the max. tube size range is limited).
