What does the term "butt joint" refer to?

The term "butt joint" refers specifically to a joint where two pieces of material are joined at their edges, without any overlap. This type of joint is commonly utilized in various applications, including woodworking, metalworking, and structural assembly. The primary characteristic of a butt joint is that the ends of the materials are aligned flush with each other, allowing for a clean and neat appearance.

In practice, butt joints can be reinforced with various techniques such as welding, adhesive bonding, or mechanical fasteners to enhance strength and stability. This type of joint is particularly advantageous when working with thicker materials, where a smooth finish is desirable for aesthetic or functional reasons. The clarity of this definition differentiates the butt joint from other types of joints, such as lap joints or miter joints, which involve overlapping surfaces or angled edges.
