What is a lap seam weld?

A lap seam weld is when two work pieces are slightly overlapped along their edges. Then this overlapping area is continuously seam welded. The overlapped metal is mashed down and welded at the same time. They overlapped slightly so this is not a butt joint. It is usually a continuous fluid tight joint. There will remain some raised metal at the joint.
