If two workpieces are to be welded together, the edge of the workpieces must first be broken by a beveled surface. This is done by machining. The result is a chamfer, also known as a bevel.
If two workpieces are to be welded together, the edge of the workpieces must first be broken by a beveled surface. This is done by machining. Or in other words, a space is created to accommodate the individual welding layers through which the workpieces are joined together. The bevel can have different shapes. The V-joint, the double V-joint, and the Y-joint are the most common shapes.
The position of the weld, the material of the workpiece, and the types of drives available - the choice of the right tool depends on various factors.
If an angle grinder is available, the beveling can be done with sulfur- and iron-free Osborn flap discs. Flap discs with a conical or straight shape are available. The angle on the workpiece determines the shape of the flap wheel.
If a workpiece made of non-ferrous metal is to be beveled, we recommend an abrasive cloth with a cooling bond as it reduces blue tarnish.

If a straight grinder or air grinder is available, chamfering can be done with carbide burrs. The milling head is made of tungsten carbide-cobalt, the shank of tool steel. Different head shapes and toothings ensure that there is the right solution for every application.
For chamfering, burrs with cross serration (Z6) are the best choice. It ensures high stock removal in a short time. If the surface quality is important, a single tooth (Z3) is recommended. In the shipyard sector, the special shipyard toothing is often used. Compared to the Z6 toothing, it has a 30% higher material removal rate.
