Beveling is a pre-welding process that manufacturers and finishing service providers use to prepare parts for welding. Manufacturers cut or shere the joining edge of metal pieces at a diagonal angle against the thickness of the metal piece. This process creates a precise, angled slope with a greater surface area for the weld. It also reduces the thickness of the butting endings of two joining metal pieces, helping to improve weld fusion and improve the overall strength of the weld. During welding, the filler metal will be applied here to penetrate and fill the gap.
This style of preparation allows welders to create strong joints to join the two butting pieces. Not only is the weld joint itself stronger, but there’s a reduced risk of centerline cracking over time. Welders can further modify the beveling process by creating a “double bevel” that they can then weld with no risk of leaving any space at the crux of the V-shaped gap.
In the case of welding, beveling and chamfering are often interchangeable as many weld prep bevels have an angled cut that only goes a portion of the way down the edge of the plate, leaving a portion of the original material at the bottom. This is known as the “land” of the bevel.
