      How does the K-TIG Welding System achieve a positive cap and root without filler material?

      Achieving a positive cap and root profile autogenously using the K-TIG Welding System is the result of the heating, expanding, cooling and contracting process of the material during a single-pass keyhole TIG, on a square-butt joint.
