The CW5 style is a heavy duty type with a standard weight carrying capacity of 5,000 lbs (2,250 kg). As an option, it can be supplied in a super duty version carrying up to 10,000 lbs (4,500 kg). Although the standard range carries parts up to 240" (6 m) long, there is virtually no limit to the maximum length to which this fixture can be manufactured.

All Jetline circumferential welding fixtures include a ma­chined base. This permits the tailstock and the welding head to be easily relocated for different parts or for welding at a different position on the same part.

All tailstocks are air-operated to apply a constant clamp­ing pressure to the part throughout the welding cycle.

The rotation of the headstock on all systems is controlled by a Jetline 9640 microprocessor controller. This can provide closed loop control of the welding speed as well as control of the complete weld sequence.

Cradle lifts are available on all models. The cradle lift assists in loading the part to the centerline of the ma­chine. Cradle lifts are manufactured specifically to suit the diameter of the part to be welded.

Expanding tooling can be provided to provide support and gas backing to the weld. This tooling is customized for the specific part diameter being welded and incor­porates copper back up segments.

A slide-away tailstock can be provided to be used in conjunction with the expanding tooling. It assists in the loading and unloading of the parts.

Jetline offers a unique range of circumferential welding systems which have been designed for use with any arc welding process and for a multitude of industrial circum­ferential welding applications.

All Jetline circumferential systems include a sturdy base unit, a powered headstock and a tailstock which can be moved along the bed to accommodate differing part lengths.

A complete range of accessories and controls manu­factured by Jetline Engineering complement the range of circumferential fixtures to permit them to be made into a fully integrated welding solution.

There are three models of circumferential fixtures avail­able:

The CWB style is suitable for light duty work. It features an integrated welding head support column and is best suited for applications where the welding is carried out one weld at a time. This style consists of two models, the CWB2 has a maximum part load of 400 lbs (180 kg), the CWB5 has a maximum part load of 1,000 lbs (450 kg). The maximum part length for both models is 240" (6 m).

The CWL style is suitable for medium duty applications. The head and tailstock part of the fixture is supplied with a separate track and carriage system. This makes it simple to carry multiple welding heads to carry out two or more welds at the same time. Optional powered carriages allow motorized linear movement. The circum­ferential unit has a weight carrying capacity of 2,000 lbs (900 kg) and can carry parts up to 240" (6 m) long.
