摘要： Provided is an electric resistance welded clad steel pipe or tube in which a region where solidification microstructure is formed, i.e. a region in a weld particularly having significant influence on properties, is reduced without impairing its function as a clad pipe or tube. An electric resistance welded clad steel pipe or tube comprises: a first layer made of carbon steel or low-alloy steel as base metal; and a second layer placed on one surface of the first layer, and made of stainless steel or a nickel-containing alloy as cladding metal, wherein the base metal is not exposed at a cladding metal-side surface of the electric resistance welded clad steel pipe or tube in a weld, and no solidification microstructure is contained in each of circular sections of 0.1 mm in radius respectively centered at specific three positions in a plane perpendicular to a pipe or tube longitudinal direction.

摘要： A water-repellent film is applied on to the surface of a welding member such as of a welding backing member disposed backside a joint defined between two mating welding bevels, a welding bevel of a base member to be welded, and a coated welding rod formed by coating a metallic core wire with a flux. The water-repellent film is formed of a hydrophobic material having a contact angle of 90.degree. or above and providing minute concavities and convexities. In a highly humid environment, during rainfall or in water, welding can be effected without weld defects such as blow holes, cracks and the like.

摘要： The method of forming a seamed metal tube having a metal coating of this invention includes applying a metal coating to the upper face of a metal strip prior to welding. The strip is then formed into an open seam tube and welded, preferably in a non-oxidizing atmosphere with the seam preferably located in the lower portion of the tube. Finally, at least a lower portion of said tube is reheated with the seam located in the lower portion of the tube, thereby causing the metal coating to flow downwardly over the seam, coating the seam. In one embodiment, the strip is preformed into an arcuate shape and coated, wherein the metal coating increases in thickness toward the lateral strip edges, such that the coating will flow over the seam following welding. The inside coated seamed tube may also be immersed in a galvanizing or metal coating bath to coat the outside of the tube. In a preferred embodiment, the inside and outside coatings comprise substantially the same metal and a single galvanizing bath apparatus is used to coat the inside and outside surfaces of the seamed tube. In another embodiment, the coating on the inner surface of the seamed tube has a melting temperature substantially below the melting temperature of the metal strip, but higher than the melting temperature of the outside metal coating. In another embodiment, a lance is provided having a free end which extends through the adjacent lateral edges of a tube-shaped strip and a nozzle which applies metal coating material over the seam. A control loop is also disclosed for improved reflow of the metal coating over the seam.
摘要翻译：形成具有本发明的金属涂层的缝合金属管的方法包括在焊接之前将金属涂层施加到金属带的上表面。然后将带材形成为开缝管并优选在非氧化性气氛中焊接，其中接缝优选位于管的下部。最后，所述管的至少下部部分被再次加热，其中接缝位于管的下部，从而使金属涂层向下流过接缝，涂覆接缝。在一个实施例中，条带被预成形为弓形并且被涂覆，其中金属涂层朝向横向条边缘增加厚度，使得涂层将在焊接之后流过焊缝。内部涂覆的缝合管也可以浸入镀锌或金属涂层浴中以涂覆管的外部。在优选实施例中，内外涂层包括基本上相同的金属，并且使用单个镀锌浴装置来涂覆缝合管的内表面和外表面。在另一个实施方案中，缝合管的内表面上的涂层的熔融温度基本上低于金属带的熔融温度，但高于外部金属涂层的熔融温度。在另一个实施例中，提供了一种具有自由端的喷枪，该自由端延伸穿过管状条的相邻侧边缘，以及在接缝上施加金属涂层材料的喷嘴。还公开了一种用于改善接缝上的金属涂层的回流的控制回路。
