Lap welds, also known as lap seams or lap joints, are a type of weld where two pieces of material overlap. The edges of the materials are brought together to form a single, continuous surface before welding. This overlap creates a region where the weld material is deposited, joining the two pieces along their extended surface.

Lap welds are commonly used in sheet metal fabrication, automotive manufacturing, and pipeline construction. Their primary advantage lies in their ability to create a strong and watertight seal, making them suitable for applications where leak prevention is crucial. The overlapping nature of the joint also provides a larger surface area for the weld, contributing to its overall strength and durability.

The welding process for lap joints can involve various techniques, including arc welding (such as shielded metal arc welding or gas metal arc welding), resistance welding, and brazing. The specific method chosen depends on the materials being joined, the required strength, and the desired aesthetic outcome. Proper preparation, including cleaning the surfaces to be joined, is essential for achieving a sound lap weld. The penetration of the weld into the overlapped material is a critical factor in the joint's performance.
