U-Tube Welding Head
Compact Orbital TIG Welding for U-Tube Applications
JWELDING U-Tube Welding Heads are designed for automatic
orbital TIG welding of U-shaped tube connections where
installation space is limited.
The compact welding head design allows stable and repeatable
welding in heat exchangers, condensers and industrial U-tube
bundle applications.
Four models are available to cover tube diameters from
Ø12.7 mm to Ø25 mm.
