An apparatus for continuous laser welding adjacent longitudinally extending of generally tubular shaped members is disclosed. The apparatus comprises a Z-bar guide for positioning and guiding the edges as they are moved toward a welding area with a laser welding device for welding the edges, and a mandrel connected to the Z-bar guide and extending internally and in the direction of movement of the members. The mandrel includes a laser beam dump positioned adjacent the welding area for absorbing light from a laser beam produced by the laser welding device and at least one roller for internally supporting and guiding the generally tubular shaped members.
