    • 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.
    • 用于涂覆本发明的焊接管(20)的接缝的方法包括将所需的粉末形式的保护性金属涂层和液体助焊剂的混合物涂覆在焊缝的内表面上,其中焊缝位于下部 的管,然后将焊缝加热到保护金属涂层的熔化温度,熔化流过焊缝的金属涂层形成粘附的冶金结合。 优选的设备包括在焊接设备中在开口接缝管的相对边缘(24)之间延伸的杆(86),并且轴向延伸穿过管以覆盖与焊接设备间隔开的焊缝。 魔杖包括将粉末状保护金属涂层(88),液体助焊剂(94)和非氧化气体(38)传送到涂抹器的三个管道,该喷射器包括喷嘴(58),喷嘴(58)将液体通量喷雾到喷嘴 接缝,并与粉末状保护金属涂层结合形成糊状物。 优选的加热装置包括邻近接缝预热接缝的第一感应加热器(100)和加热整个管的全身线圈(102)。

    • A method of coating the welded seam of a metal tube (20) comprising heating the weld area only of the metal tube to a first temperature which is less than the melting temperature of a protective metal coating, applying the protective metal coating over the seam and heating the entire tube, preferably with a full body induction coil (78), to a second temperature which is at least equal to the difference between the first temperature and the melting temperature of the metal coating, such that the temperature of the seam area is heated to a temperature equal to or greater than the melting temperature of the metal coating, whereby the metal coating firmly adheres to the welded seam. In applying a coating over the exterior surface of the seam, the coating is preferably applied by thermally spraying (70) molten metal coating material over the seam.
    • 一种涂覆金属管(20)的焊缝的方法,包括将仅金属管的焊接区域加热到小于保护金属涂层的熔融温度的第一温度,将保护金属涂层施加在接缝上,以及 将整个管,优选用全身感应线圈(78)加热到至少等于金属涂层的第一温度和熔融温度之差的第二温度,使得接缝区域的温度为 加热到等于或大于金属涂层的熔融温度的温度,由此金属涂层牢固地粘附到焊缝。 在将涂层涂覆在接缝的外表面上时,优选通过在接缝上喷涂(70)熔融金属涂层材料来施加涂层。
