A weld made from both sides of the joint between two pieces of metal is referred to as what?

A weld made from both sides of the joint between two pieces of metal is referred to as a double weld. This type of weld is distinguished by its application on both surfaces of the joint, creating a stronger connection between the two metal pieces. By welding from both sides, the welder ensures better fusion and strength, particularly in applications that demand high structural integrity.

In contrast, other types of welds, such as a single weld, are made from only one side and may not provide the same level of strength. Corner and butt welds also pertain to specific joining methods but do not necessarily indicate the number of sides being welded. Thus, a double weld is the correct term for a weld performed on both sides of a joint.
