Abstract
The connection between tube and tube-sheet is usually achieved by means of expanding the tube so that it fits tightly in the hole by means of radial pressure. In service, especially when there are fairly high temperature or pressure differentials, such a joint with expansions, only, may deteriorate. Seal welding avoids this condition. Seal welding with automatic argon arc is more favourable for many applications when compared with other welding processess. This process results in welds of exceptional quality together with low operating costs, completely automatic operation, consistent results and high productivity.
