Welding Seamer

Longitudinal Welding Seamer Systems

Our longitudinal weld seamers use durable linear rails with bearing blocks for a smooth seam welding process.

MITUSA custom linear seamers deliver strength and accuracy during the longitudinal seam welding operation. Creative design allowing all needed welding equipment to be mounted on the linear rail side beam carriage away from the floor.

This resolves less tangled wires while reducing the need to maintain longer control cables. Reducing cable noise interference problems. Keeping the weld control and power supply together within easy access for the operator.

The linear travel track is machined to a 0.005-in straightness tolerance so that the seam weld is as straight as possible based on the joint preparation. Precision weld seamers are designed for longitudinal welding of all types of butted metals with 100% penetration welds.

Complete ergonomic access to welding controllers on all of our linear welding seams equipment. Our design gives the track a strong hold and allows free travel of the side beam carriage. Carriage travel car carries 750 lbs of seam related welding gear and controls for easy operator access.

Seamer Table Top Alignment Device - Finger Clamp Tooling

Innovative tooling allows the longitudinal welding equipment to apply pressure to clamp the weldment butt weld joint ends together. Part seam welds are done on a conductive water cooled insert tooling like copper or aluminum, with variable required force used along the clamped joint. This eliminates the heat to distortion the part during the seam welding process like no other design.

Edge Alignment Tool, Copper Fingertips and Inserts

In addition the welding seamer design uses the highest quality standard or custom seamer table top cooling clamp tooling for the best results. Copper finger tips and insert tooling absorbs and dissipates welding heat through our proprietary water cooled back up bar type seamer bed insert tool.

The weld seamer's tooling can be made from copper, stainless steel or aluminum alloy, this is based on the customer's requirements.

Applications for welding seamers are pipe seam welding, linear welding seam joints of cylindrical parts of all sizes.
Including tubes, pipe or cylinder seam welding.

Common welding seamer applications are flat plate sheet steel joining. formed box edge joints, square or rectangle parts can be longitudinal seam welded along the precise butted joint based on the metal thickness.

Our welding controls working in concert with seamer carriage as it travels on the side beams linear rails. Using two 24 VDC motor controllers one for the carriage and another for the Capstan wire feeder.

These weld control devices deliver accurate encoder feedback for precision smooth carriage travel speed control on the precision built linear rail side beam welding seamer.
