Abstract
A linear welding process and apparatus connects fluid-filled tubes in a sterile manner. The linear welder includes a base on which a carriage is slidably mounted. A pair of side by side arms are secured to the carriage as are a pair of tube holders. A pair of clamping jaws are mounted on the arms to clamp a pair of tubes in the holders. The arms are movable for passing the clamped tubes into contact with a heated wafer which cuts the tubes into tube sections. The tube sections are realigned and a pair of sections are butt welded together.
