  Specification:
  Small diameter tubing, defined as round tubing with an outside diameter of 38mm or less, is used in a variety of industrial applications. For joining of small diameter tubing, particularly for more critical piping systems where weld quality or product purity is a concern, orbital welding has become the preferred joining method. Orbital tube welding is generally a fusion process in which the edges of the joint are melted and fused together without the addition of filler material.
  The size range for orbital fusion welding is 3.2mm-177.8mm OD but the most common size is 6.3mm OD, 0.9mm wall which is used extensively for semi-conductor process gas lines. Orbital weld heads are of the enclosed type and form a chamber which is filled with inert gas during welding to prevent oxidation of the tube OD during welding. Each weld head accommodates a range of sizes, which is accomplished by changing the tube clamp inserts to fit the tube diameter on both sides of the head, or with the smaller heads, by changing the clamp assembly.
