Define the term 'beveling' in welding.

Beveling in welding refers specifically to the process of cutting the edges of metal at an angle, which is crucial for ensuring proper weld penetration and strength. By creating bevels on the edges of the materials being joined, a welder can facilitate a thicker joint that is better suited for welding. This angled cut allows the molten filler material to flow more effectively into the joint, enhancing the stability and integrity of the finished weld.

Additionally, beveling helps achieve a smoother transition between the base metals, reducing the likelihood of stress concentrations that can occur with a straight joint. This technique is often employed in situations where the materials have significant thickness or where a groove weld is needed to ensure adequate fusion between parts.
