ABSTRACT:
A continuous seam weldment is established between moving strips of sheet material by forming a converging Vee geometry between the moving strips, applying force at the point of convergence and directing a laser beam into the convergence Vee. The laser beam should be focused at a focal point lying only in a narrow range from essentially at the point of convergence to a location downstream thereof.
