The Tank body is automatic welded using Argon gas inside and out. So the central body weld seam is free of pore and splatter residuce as well. This results in an internal surface that prohibits contamination of the keg contents and provides a smooth surface allowing the flow of all cleaning and sterilizers during the cleaning process.
The top and bottom skirts are also welded to the stainless steel Tank body with a continous seem. The high automatic welding process guarantees an extremly smooth and splatter free weld, not using any addtional material.
