Laser welding is high power density welding method which is higher speed and productivity, lower thermal deformation, without material restrictions for car body welding. But, in case of zinc coated sheet metal welding, the gap is needed 0.1~0.2㎜ to avoid bead blowup.<BR> This paper describe that in used dimple and pressure roller tool to improve laser welding quality for 3-layer zinc coated sheet metal.
