For this purpose, the utility model adopts the following technical scheme: the metal composite pipe is characterized by comprising a metal composite strip part and a welding line part, wherein the metal composite strip part is formed by curling a metal composite strip, iron or stainless steel is used as a base material, one surface or two surfaces of the base material is covered with a metal forming covering metal layer different from the base material, an atomic infiltration bonding layer is formed between the covering metal layer and the base material, the welding line part comprises a welding line and a welding line cladding metal layer clad on the surface of the welding line, the welding line cladding metal layer and the covering metal layer are of the same metal, and an atomic infiltration welding line bonding layer is formed between the welding line cladding metal layer and the welding line.
The metal of the covering metal layer is copper, aluminum or zinc.
The thickness of the cladding metal layer or the welding seam cladding metal layer is not less than 0.03 mm.
When the metal composite pipe is manufactured, a metal composite strip material of which the base material is iron or stainless steel and one surface or two surfaces are covered with metals different from the base material is transversely curled into a cylindrical metal composite strip material part at normal temperature, two longitudinal side end surfaces opposite to the metal composite strip material are opposite to each other to form a longitudinal straight seam, then the two opposite longitudinal side end surfaces are welded, the welded seam is heated, the same metal as the metal composite strip material covered with the metal layer is clad on the welded seam, the clad metal is crystallized and solidified on the welded seam to form a clad metal layer, and an atomic mutual infiltration bonding layer is formed between the clad metal layer and the welded seam. The welding method adopts argon arc welding, laser welding or high-frequency welding.
The utility model can achieve the following beneficial effects: the metal composite strip material with different kinds of metal covered on the base material is coiled at normal temperature and welded to form a metal composite pipe, and then the metal is clad on the welding seam to form an atomic mutually-permeable bonding layer, so that the bonding force between the inner metal layer and the outer metal layer is strong, a common steel strip pipe making machine can be used for making pipes, the long-size metal composite pipe can be prepared, the manufacturing is convenient, the metal layers can be covered on the inner surface and the outer surface of the base material, and the type and the application range of the metal composite pipe are enlarged.
