The corner seam clamping device is a tool for holding sheet metal or profiles securely and firmly at right angles during welding. It holds the components firmly in the desired position, enabling precise, even corner seams to be produced. This ensures that the welding quality remains consistently high - whatever the sheet thickness and over many production cycles. With the precise systems from Schnelldorfer Maschinenbau, you can look forward to permanently clean weld seams, less rework and high efficiency throughout the entire production process.
What is a corner seam - and why is it challenging?
A corner seam is created when two sheets are welded together at right angles. This is the case with frames, containers or housings, for example. This joint must not only be stable, but also visually appealing and distortion-free. The tricky thing is that welding generates heat, which can lead to tension, deformation or uneven seam quality. A high-quality corner seam clamping device compensates for these effects: It holds the workpiece securely, stabilizes the arc and paves the way for straight, clean weld seams, without any need for post-correction.
Clamping concepts for corner seam clamping fixtures
The choice of the right clamping concept determines how well Corner seam welding succeeds in the end. A corner seam clamping fixture must securely fix components of different sheet thicknesses and material thicknesses, prevent distortion and ensure uniform weld seams - regardless of whether it is for individual parts, small batches or complete series production. Depending on the application, various clamping devices are therefore used, which differ in terms of force, mechanics and degree of automation.
Manual clamping fixtures - flexible for individual parts and prototypes
Manual clamping devices are simple in design, robust and ideally suited for single pieces or small batches. The operator clamps the workpieces themselves using levers, clamps or screw systems - a clear advantage for frequently changing components or small sheet thicknesses.
They therefore score points with their high flexibility and are particularly useful when quick adaptation to different workpiece sizes, angles or lengths is required. Despite the manual design, they ensure good welding quality and even corner seams, as the workpiece always remains stable in position.
Advantages at a glance:
- Low acquisition costs and easy maintenance
- Quick changeover for changing components
- High user-friendliness and direct control
- Ideal for small companies
Pneumatic clamping devices - fast, precise and efficient
Pneumatic corner seam clamping devices use compressed air to hold sheet metal or profiles in position. They have an optimum ratio of speed and clamping force and are ideal for daily use in production. The uniform clamping counteracts deformation, while the weld seam remains constant even at high welding speeds.
Advantages at a glance:
- Automatic, uniform clamping without manual intervention
- High repeat accuracy for series processes
- Reduced reworking thanks to stable corner seam connections
- Very good cost-effectiveness for medium and large quantities
Hydraulic clamping fixtures - maximum force for heavy components
Hydraulic clamping devices are used for large or thick-walled components. They generate high clamping forces to securely fix even solid workpieces made of steel, stainless steel or structural steel. As a result, the positions remain stable even at high temperatures and during long welding processes and the seam quality remains constant.
Advantages at a glance:
- High clamping force for heavy or large-format welded parts
- Constant voltage over long production times
- Low deformation despite high temperatures
- Ideal for automated welding machines and high performance
Compact and chain tensioners - space-saving and adaptable
If there is little space available in the welding system, compact clamps or chain clamps come in handy. They have a high clamping force in a small space and also adapt to irregular or round workpieces. They are particularly useful for corners, pipes or curved sheet metal. The good thing is that their modular design means they can be easily integrated into existing machines.
Advantages at a glance:
- Flexible adaptation to different workpieces
- Space-saving design with high mechanical stability
- Quick changeover for variable areas of application
- Suitable for manual, semi-automatic and robot-assisted welding processes
Modular clamping systems - maximum flexibility in series production
Modular corner seam clamping fixtures are the all-rounders in modern welding systems. They consist of interchangeable modules that can be adapted to different components, sheet thicknesses, lengths and angles. These systems are particularly suitable for companies with changing models and frequent product adaptations. Modular setups also significantly increase efficiency: once set up, welding processes can be repeated quickly - with consistently high quality and minimal rework.
Advantages at a glance:
- High flexibility with changing workpieces and series sizes
- Shorter set-up times and easy adjustment
- Compatible with laser and MIG/MAG
- Durable design, perfect for industrial welding machines
Whether manual, pneumatic, hydraulic, compact or modular - with a corner seam clamping fixture, you are opting for your own type of precision, welding quality and cost-effectiveness. At Schnelldorfer Maschinenbau, we can help you find the fixture that suits your welding process. For welders
Corner seam welding machine - technology for clean joints
A corner seam welding machine joins sheet metal, housings or profiles precisely at a 90° angle. Thanks to the automatic clamping devices, there is no need for time-consuming set-up, as the welded parts are securely fixed and perfectly aligned. The result is impressive: clean, even weld seams that remain stable even with large workpieces. The good thing is that corner seam welding is suitable for individual parts as well as for small series and complete series production. With the right clamping device and the right welding machine, every weld seam sits where it should.
MIG, MAG, TIG - flexibility for every application
Whether MIG, MAG or TIG processes - Schnelldorfer's corner seam welding machines are designed for all common welding processes. They weld steel, stainless steel, aluminum or structural steels reliably and with consistently high quality. The corner seam clamping device holds the workpiece securely at all times and in any position. For reproducible results over many production cycles.
MIG/MAG welding - efficient for thicker materials
The MIG/MAG welding process is particularly suitable for thicker sheets and structural steels. The high welding speed and even material application produce strong corner seams in the shortest possible time. Combined with a corner seam clamping device, you benefit from a stable seam, reduced set-up times and consistent seam quality. This means that even complex components can be produced economically - with optimum performance, a long service life and minimal wear.
This is what makes MIG/MAG welding so convincing:
- High deposition rate and excellent productivity
- Durable weld seams with large material thicknesses
