<p>Pressure feet for association with a laser welder head to apply pressure as closely as possible to workpieces adjacent the welding zone whereby maximum weld penetration and quality are achieved. Welding pressure feet includes roller means engagable with the uppermost portions of the workpiece serving to define a desired width of welding zone. The provision of inclined roller means facilitates the achievement of a welding zone of minimal width.</p> |
