Enclosed Weld Heads

Due to their design, enclosed weld heads offer complete top layer protection of the weld joint due to continuous weld joint fluting during the welding process with protective gas. This reduces the joints’ tempering colours. A corresponding set of collets is also required for each tube outer diameter due to the design.

The wire cannot be fed cold. The welds are made in the I-joint with precise joint preparation (90° – saw cut, face if necessary). Advantage: Enclosed weld heads are comparably narrow and particularly suited to environments where space is tight.

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.

Gas-shield Collets

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).
