Tube to Tubesheet Welding Systems - Arc Machines, Inc.
The Model 96 is an automated weld head designed for high-speed, high-production autogenous welding of tubes to tubesheet. Welds made with this head, utilizing the GTAW (TIG) welding process, can pass the most rigid specifications.
The weld head is held in place on the tube to be welded by an expanding mandrel. This mandrel is actuated by a single button, conveniently located in the handle. Actuation of the mandrel holds the weld head firmly to the tubesheet and positions the torch concentric to the tube to be welded. The Model 96 features a completely enclosed purge chamber. The gas chamber eliminates the use of gas cups and provides superior shielding for materials which oxidize easily, such as titanium.
