Pipe welding is performed by an automatic method with the use of plasma technology. To produce plasma, i.e. ionized gas, it is required to heat it to a sufficiently high temperature. As with TIG welding, arc in plasma welding is formed between non-consumable electrode and the workpiece. For pipe welding, we utilize our many years of experience in the production of stainless steel and acid-resistant steel chimney systems, whereas the welding process itself is completely automated.
