Kerf geometry profile
Kerf geometry describes the shape of the cut in sheet metal welding, consisting of cut width, bevel angles, and inserts. It influences fit and material behavior.
Physicochemical Mechanism of Action
The cutting gap geometry defines the shape and size of the cut in sheet welding. It includes the width of the gap, the flank angles and possible features like grooves or edges. This geometry influences how the material leaves the cut and which mechanical loads it withstands.
Metallurgical Relevance & Welding Risks
An unsuitable cutting gap geometry can lead to various problems. A too-narrow gap can overload the material, which leads to cracks or distortion. A too-large gap raises the stresses and can destroy the material structure. The geometry also influences the fit accuracy of the milled parts, since it determines the distance between the cut lines.
Workshop Practice & Instructions
To ensure an optimal cutting gap geometry, keep these values in mind:
• Cut width: 0.5 to 1 mm for common sheets.
• Flank angle: 20° to 30° for a good balance between ease of cutting and material waste.
• Features: Use grooves or edges to improve fit accuracy and reduce stresses.
These values should be adjusted according to the material type and welding process. A correct setup of the cutting gap geometry is crucial for defect-free sheet welding and the production of high-precision parts.
