摘要： The method of forming a seamed metal tube (20c) having a metal coating (56) of this invention includes galvanizing the strip (20) prior to welding. The strip (20) is then formed into an open seam tube (20b) and welded in an inert atmosphere with the seam (71) located in the lower portion of the tube. Finally, the metal coating (56) is caused to flow downwardly over the seam (71), coating the seam (71) by several means. In one embodiment, the strip (20) is preformed into an arcuate shape (20a) and galvanized, wherein the zinc coating (56) increases in thickness toward the lateral strip edges (48), such that the coating (56) will flow over the seam (71) following welding. The tube (20c) may also be reheated following welding, preferably in an enclosure (78) containing an inert atmosphere which includes the weld apparatus (62). In another embodiment, an inert gas is directed over the inner and outer surfaces of the tube (20c), adjacent the seam (71), driving the molten metal downwardly over the seam (71) to coat the seam (71). In another embodiment, the lateral edges (48) of the strip (20) are formed with indentions or grooves (188) directed toward the lateral edges (48) which direct the molten metal downwardly over the seam (71).

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 of forming a seamed metal tube (20c) having a metal coating (56) on at least an inside surface of the tube (20c) from a continuously moving, relatively flat metal strip (20a) is disclosed. The primary feature of the inventive process is the step, after forming and welding the seamed metal tube (20c), of locating the seam in a lower portion of the tube (20c) and reheating at least that lower portion of the tube (20c) to melt the coating (56). The coating (56) is thereby caused to flow downwardly over and to coat the inner surface of the seam. The result is a seamed tube (20c) with a more corrosion resistant seam region.

摘要： The method of forming a seamed metal tube (20c) having a metal coating (56) of this invention includes galvanizing the strip (20) prior to welding. The strip (20) is then formed into an open seam tube (20b) and welded in an inert atmosphere with the seam (71) located in the lower portion of the tube. Finally, the metal coating (56) is caused to flow downwardly over the seam (71), coating the seam (71) by several means. In one embodiment, the strip (20) is preformed into an arcuate shape (20a) and galvanized, wherein the zinc coating (56) increases in thickness toward the lateral strip edges (48), such that the coating (56) will flow over the seam (71) following welding. The tube (20c) may also be reheated following welding, preferably in an enclosure (78) containing an inert atmosphere which includes the weld apparatus (62). In another embodiment, an inert gas is directed over the inner and outer surfaces of the tube (20c), adjacent the seam (71), driving the molten metal downwardly over the seam (71) to coat the seam (71). In another embodiment, the lateral edges (48) of the strip (20) are formed with indentions or grooves (188) directed toward the lateral edges (48) which direct the molten metal downwardly over the seam (71).
