Metal Bellows Forming Machine

Forms metal tube blanks into corrugations using dedicated forming tooling for the manufacture of metal bellows and expansion-joint bellows elements.
Metal Bellows Rolling Forming Machine

Uses forming rolls to shape metal tube blanks into annular corrugations for bellows forming or trial production.
Automatic Arc Welding Machine

Uses automated travel and wire-feeding mechanisms for stable longitudinal or circumferential seam welding of shells, pipes, and expansion-joint assemblies.
Horizontal-Arm Automatic Welding Machine

Positions the welding torch with an adjustable horizontal arm for automatic circumferential or longitudinal seam welding of shells, pipes, and related components.
Column-and-Boom Welding Manipulator

Uses vertical column travel and horizontal boom movement to position the welding head for automated welding of large shells, pipes, and fabricated components.
Corrugated Plate Metal Plate Cutting Machine

Cuts metal plate or corrugated plate to size for subsequent forming, assembly, and welding operations.
