Fit-Up Systems and Options

Our advanced fit-up systems are designed to streamline the assembly of growing sections, incorporating tack welding processes to facilitate subsequent multi-seam welding. The integration of the versatile multi-seam welding station and column & boom welding manipulators’ offers flexibility in the welding process.

When utilising the multi-seam welding station, sections are welded further down the production line. Benefiting from the precision of a column & boom welding manipulator for both internal and external welding. The column and booms traversing capability enables welding on one line while tack welding occurs on another growing line, optimising production efficiency.

The fit-up system is engineered with movable wheels to manipulate each can, ensuring plate offset adjustments for seamless integration around the entire circumference during tack welding. Customisable with a range of add-ons, including conventional rotators, SAR rotators, additional wheels for precise can positioning, and options for hydraulic or electrical movement of the rotators, the fit-up system is adaptable to various setups.

Furthermore, the fit-up system can be equipped with a lifting unit for growing sections, reducing reliance on cranes. Longitudinal rollers are also available to facilitate section growth with minimal dependence on overhead cranes. This comprehensive system ensures optimal efficiency and adaptability in diverse manufacturing environments.

Longitudinal Seam Welding Fit-Up System

Our fit-up system, designed for longitudinal seam welding, offers versatility with options for both typical conventional rotators and the alternative SAR configuration, catering to customer preferences.

Ensuring stable welding of the outer long seam, the system can be customised with support rollers on the can’s side or a top support that supports the top of the can internally. The top support is equipped with rotating wheels, allowing seamless rotation even as it stabilises the can during the welding process. This design provides a reliable and adaptable solution for longitudinal seam welding applications.

Flange to Can

Rotators specifically designed for the Flange-to-Can Column and Boom welding system ensure precision when welding flanges. In certain scenarios, this versatile system can also be employed for welding the initial few cans.

The FTC rotators are typically self-aligning, featuring counter rolls that prevent the can from rolling off the wheels. Standard with a short stroke system for adapting to the can’s diameter, these rotators contribute to a more compact overall design.

Equipped with four gear motors, the rotators offer optimal and stable rotation during the welding process. Employing the FTC system for attaching and welding flanges enhances the efficiency of each growing line, enabling the production of a greater number of full sections.
