    Abstract: Provided are metal structures and methods of forming such structures for use in oil, gas and/or petrochemical applications that are joined with non- ferrous weld metal compositions or a high alloy weld metal compositions. The welded metal structures include two or more segments of ferrous or non-ferrous components, and fusion welds, friction stir welds or a combination thereof bonding adjacent segments of the components together, wherein the welds comprise a non-ferrous weld metal composition or a high alloy weld metal composition that is substantially different from the metal composition of the two or more components. The resultant welded structures exhibit improvements in fatigue resistance, toughness, strain capacity, strength, stress corrosion cracking resistance, and hydrogen embrittlement resistance compared to traditional iron- based weld compositions. The structures and methods of forming such structures are advantageous in joining metal components in applications for natural gas transportation and storage, oil and gas well completion and production, and oil and gas refinery and chemical plants.

    Abstract: A method for joining clad metal plates having a protective layer (27), e.g. titanium, and a substrate layer (28), e.g. carbon steel, includes firstly removing margins (29) of protective layer along edges of the clad metal plates to be joined. The substrate layers are then welded together to form an exposed substrate weld (31). Covering material (38) of the same type as the protective layer (27) is then located along the exposed substrate weld (31) to a level substantially flush with an outer surface of the protective layer (27). The substrate layer (28) is heated prior to welding the covering material so that the covering material is pre-stressed when cooled. The method may be used to fabricate reaction vessels having seams that do not stand proud of the remainder of the interior surface of the vessel. The low profile seams are less susceptible to erosion than has been the case in the past so that longer-life vessels can be produced. The invention encompasses vessels such as autoclaves, crucibles and reaction vessels formed of clad plate joined by the method.

    Abstract: A pulsated magnetic welding method and a welding induction coil for sealing a vessel (10) are provided. The method includes providing a vessel's body (11) having an open end (12) a cover (13) including a welding part and a brim part (15). A diameter of the cover (13) at the welding part (14) is less than the diameter of the vessel's body (11) for providing an air gap (16) between the vessel's body (11) and the welding part (14). The cover (13) is placed within said open end (12) of the vessel's body (11). A welding induction coil (18) is provided around the vessel's body (11) at the place where the welding part (14) of the cover (13) is located. The welding induction coil (18) is energized to generate a pulsed magnetic force sufficient to cause bending a portion (19) of the vessel's body (11) in a radially inward direction around the cover (13) in the air gap (16). The pulsed magnetic force has such a value so to provide mutual diffusion of atoms of the vessel's body (11) and the cover (13) at their impact, thereby to weld the vessel's body (11) and the cover (13) to each other.
