Butt/fillet weld machine

For linear seam connections on blunt or rectangular welded sheets

Welding along clearly defined lines

Fillet welding machines from Klumpp Welding are designed for straight welds with a fixed start and end point. Used for blunt or rectangular joined sheet metal connections, they enable stable, reproducible welds — ideal for large sheet formats and geometrically simple components. If necessary, camera tracking of the weld seam can be used to automatically compensate for deviations in the component position.

Details on Fillet/Butt Weld Machines

When is a fillet/butt weld machine used?

The fillet/butt weld machine is designed to weld two straight sheets together in a 90° joint. This enables the creation of very large structures from individual sheet metal panels, for instance in shipbuilding, where standard panels are insufficient in size or shape and components must therefore be assembled from multiple segments.

Your Benefits with the Fillet/Butt Weld Machine

The system can be equipped with feeding technology to precisely guide sheets to the welding area. A 180° rotation function is also optionally available for welding from both sides.

Additionally, inert gas shielding of the weld root is possible to specifically protect the back of the weld and enhance the welding result.

The right clamping technology for your application

For large sheets, hydraulic clamping is common. This is because components often exhibit distortion from upstream processes like flame cutting. Hydraulic or high-pressure hydraulic clamping provides more force to reliably secure and align the sheets.

Precise and secure clamping of components

The clamping dogs are moved at an angle, or a slight angle, towards the workpiece to precisely bring the sheet edges together.

FAQs

What workpiece width can be processed?

The sheet metal panels to be processed can be up to 18 meters wide.

What materials and material thicknesses can be processed?

Material thicknesses from 1 to 100 mm can be processed. Additionally, solutions for up to 300 mm are also feasible.

Is automation possible, and what level of automation does the machine offer?

The level of automation ranges from a welding process along a linear axis to the positioning of components, for instance, by retrieving them from a material storage unit using robots or linear axes. The subsequent welding of these parts can also be automated.

How long can the workpieces be?

The largest machines built to date had a welding length of 18 or 20 meters, respectively. Larger versions are possible. The total workpiece length can be significantly greater than the actual welding length.

Which welding processes are available?

All welding processes are available.

Is the weld possible on the inside or outside?

Welding is usually done on the outside.
