Chamfering machine WKF 170

Weld seam preparation refers to the measures and work steps that are taken before the actual welding process in order to create optimum conditions for a high-quality and stable welded joint.

1. To improve the weld quality: to ensure a strong, non-porous connection.
2. Facilitating the welding process: better accessibility and processing of the seam.
3. Avoidance of defects: reduction of tension, cracks or inclusions in the seam.

1. Cleaning the welding surfaces: Removal of dirt, oil, rust, scale or other contaminants that could affect weld quality.
2. Chamfering the edges of the workpiece: Machining the edges to produce the correct seam type (e.g. V, X or K seam). This improves the penetration of the weld and increases stability.
3. Edge rounding or bevelling: For example, by milling, grinding or machine chamfering to obtain the desired seam geometry.
4. Selection of the right seam type: Depending on the material, material thickness and application.
5. Positioning of the workpieces: Ensuring that the parts are precisely aligned and fixed to ensure a consistent welded joint.

• Handheld deburring and chamfering tools: For smaller or simpler jobs.
• Edge grinding machines: Stationary or mobile devices that ensure precise weld edges.
• Grinding machines: For smoothing and cleaning edges.

Weld seam preparation is an essential step to ensure the longevity, stability and aesthetics of the welded joint.

Edge rounding is part of the deburring process and removes sharp edges. This is necessary to ensure safety during handling. 

Metal edges are rounded by milling or chamfering with special edge milling machines or deburring machines. This involves the targeted removal of material to create an even radius edge.

There are various machines such as deburring machines, edge milling machines or chamfering machines that have been specially developed for rounding edges. Assfalg offers a wide range of machines for perfect results, adapted to different workpiece shapes and material types.

An edge milling machine with V-prism is required when small workpieces need to be processed. The V-prism ensures a secure hold and enables precise processing of the edges.
