What type of joint is formed by lap joints in sheet metal assemblies?

Lap joints in sheet metal assemblies are characterized by their construction, where two pieces of metal overlap each other. This design allows for a significant surface area to be bonded or fastened together, which helps distribute the loads across the joint effectively.

In sheet metal work, lap joints are commonly used because they can be efficiently assembled using various fastening methods, including riveting, bolting, or welding. The overlapping nature of the joint provides enhanced strength and stability, making it suitable for a wide range of applications, from aircraft structures to automotive components.

The other options present different types of joints that do not correspond to the nature of lap joints. For instance, joints that involve pieces of metal without overlap or those solely using welding or adhesive materials describe different assembly methods and techniques, distinct from the overlapping configuration that defines a lap joint.
