Enclosed Weld Heads

In a design with enclosed weld heads, the weld joint receives a complete top layer coverage by the constant flow of shielding gas during the welding process. This avoids the colouring of the weld. This installation also requires a corresponding set of clamping jaws for each outer diameter of the tubes.
A cold wire feed mechanism is not possible. Weldings are performed in square butt with precise joint preparation (if applicable, a 90°saw cut is provided). Advantage: Enclosed welding heads are comparatively narrow and adapt easily to confined space conditions.

Enclosed orbital weld heads by Orbitec

Clever, customised with high precision

 

Our enclosed orbital weld heads stand for excellent welding results with a maximum customisation. For this reason, the implementation of Orbitec cassette-type weld heads meets the highest quality demands.

The Orbitec feed unit has a separated hose assembly and weld head, while multiple cassette weld heads can be operated with one feed unit only (exception: Microfitting weld head). This way a higher flexibility is obtained at reduced costs.

All Orbitec heads are also available in a gas or water coolant design and can be retrofitted as required (Exception: Microfitting weld head). But the gas coolant design of the heads fits the typical cassette welding head applications very well. When the thresholds of a cassette welding head are reached, the Orbitec cassette-type weld heads with water coolant design are recommended. Compared to other providers, the essential components for the heat input are sustainably cooled by a high water flow.
