Beveling
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.
What is beveling and
why is it important?
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.
Which tool is used for beveling?
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.

A compact buff, purely made of sisal web. It is a hard, aggressive tool. Sisal is a natural material, perfect for the polishing process due its excellent compound retention properties.
Airway Open Double Cloth Bias Sisal (ODCBS)
A flexible and economical cutting tool with irregular folds of sandwiched sisal and cotton cloth quilted together. The quilting of the cloth and sisal provides flexibility in the buffing of contoured parts, and enables the buff to effectively hold compound. These buffs can produce an aggressive cut or color finish and adapt well to any surface.
Airway Open Bias Sisal Buff (OBS)
A flexible and economical cutting tool with irregular folds of sandwiched sisal. These buffs offer a heavy cutting action with the flexibility to use on flat or contoured surfaces.
Airway Cotton Buff
Made from the tightest quality cloth specifications, these cloth buffs set the industry standard for quality and performance. The standard ventilated buff is suitable for almost every step in the polishing process. This buff runs cooler than stitched buffs, is more flexible and does a better job on contour work. The irregular folds fixed to a metal clinch ring form a flexible and economical buff.
Airway Mill Treated Cotton Buff
This type of buff is constructed using the highest quality material and is biased to reduce fraying and increase life. This makes them effective finishing tools for ferrous & non-ferrous metals, marble, plastics, and other materials. Mill treated buffs offer a firmer hand and can provide a one step cut and color process.
Airway Polycotton Buff
Similar to the standard ventilated buffs this buff is flexible and versatile. This type of buff is constructed using the highest quality polycottons and is biased to reduce fraying and increase life. Various qualities of gray cloth can be selected depending on the results required. The irregular folds fixed to a metal clinch ring form a dense and economical buff for coloring.
Diamond Cut Contact Wheel
This wheel is used with coated abrasive sanding belt operations as the carrier of abrasive belts and does not touch the product. Made from rubber sections versus cloth makes this contact wheel a durable and cooler wheel to carry belts. Pressed discs are provided to protect sections, maintain structure, providing firmness and keeping the edges from breaking down. The material allows flexibility when needed for contoured edges and parts as they pass across the abrasive belt surface. Used in automated and manual polishing coated abrasive belting applications. The contact wheel is available in multiple configurations and densities.
Conventional Cotton Buff
These buffs are made with 100% cotton. Loose full disc buffs are made with 1 row of sewing around the arbor hole. They are soft and flexible and are ideal for reaching uneven surfaces while buffing or coloring metals, hard rubber, marble and plastics. Spiral and concentric sewn buffs are harder than loose buffs.
Conventional Sisal and Cloth/Sisal Buff
Full disc sisal buffs are used for cut down operations of ferrous and non-ferrous metals. They are constructed from top quality sisal, sewn and treated for added cut and life. Cloth/Sisal conventional buffs alternate cloth and sisal ply to create the desired firmness of the buff. The use of the cloth in the buff adds value in compound retention and softens the buff for contoured parts. The combination of cloth and sisal provides cutting action and high color on steel and aluminum parts.
Airway Cloth Hot Pleated Buff
These buffs have a soft face with some flexibility and are effective tools for contact buffing and provide excellent cut and color options. The pleats are designed to allow for maximum face coverage and flex during mush buffing. The pre-pleating of the cloth causes edge surface to have a random configuration and the plies do not all lay together. This will help eliminate streaking when no oscillation is possible. This buff makes up a softer wheel to reach into recesses and contours.
