摘要： The method for coating the seam of a welded tube (20) of this invention includes applying a mixture of the desired protective metal coating in powdered form and a liquid flux over the internal surface of the welded seam with the welded seam located in a lower portion of the tube, then heating the welded seam to the melting temperature of the protective metal coating, melting the metal coating which flows over the seam forming an adherent metallurgical bond. The preferred apparatus includes a wand (86) which extends between the opposed edges (24) of the open seam tube in the welding apparatus and extends axially through the tube to overlie the welded seam spaced from the welding apparatus. The wand includes three conduits transmitting the powdered protective metal coating (88), liquid flux (94), and nonoxidizing gas (38) to the applicator which includes a nozzle (58) which atomizes and sprays the liquid flux over the internal surface of the seam and which combines with the powdered protective metal coating to form a paste. The preferred heating apparatus includes a first induction heater (100) adjacent the seam which preheats the seam and a full body coil (102) which heats the entire tube.

摘要： 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.

摘要： The method forms a thin layer of metal mesh (14) on the surface (12) of the implant (10) for the bonding with a porous surface layer (16) to prevent the formation of notches within the body of the implant (10). The layer of metal mesh (14) can be formed by a number of known methods including conventional welding processes such as arc welding, resistance welding, electron beam welding, laser beam welding, friction welding, ultrasonic welding, cladding. The porous metal surface layer (16) is preferably formed from titanium wire or titanium beads in a known process. The porous surface layer (16) is bonded by a known process such as diffusion bonding, sintering, welding, or cladding. By bonding the porous surface layer (16) to the thin layer of metal mesh (14), notches normally formed in the body of the implant (10) are substantially eliminated. Therefore, the designer of the implant (10) is not limited as to the location and amount of porous surface layer (16) to be placed on the implants (10).
