What is the term for the weld that extends around the joint?

The term for the weld that extends around the joint is referred to as boxing or end return. This type of weld is typically used to create a fully enclosed weld around the joint, providing increased strength and structural integrity. The boxing weld typically involves a continuous weld that wraps around to join two surfaces together at the edges, often applied in situations where added reinforcement is necessary, such as in corners or laps.

In structural welding, understanding the terminology and definitions of different weld types is crucial. For instance, a fillet weld is used to join two surfaces at an angle and does not wrap around the joint. A butt weld is employed to join two pieces of metal along their edges, aligning them in the same plane rather than around a joint. Meanwhile, a groove weld is formed in a prepared groove and is commonly used for thicker materials or when deeper penetration is required. Each of these welding techniques has its specific applications and characteristics that distinguish them from boxing or end return welds.
