Abstract: A welded line pipe structure for use in transporting petroleum and a natural gas being corrosive, which comprises a martensitic stainless steel containing 8 to 16 % of Cr and 0.05 % or less of C, wherein a portion reduced in the content of grain boundary Cr being located directly beneath a welding oxidation scale has a Cr concentration of 5 % or more. The Cr concentration of the portion being reduced in Cr content can be achieved by adopting appropriate conditions in the circumferential welding of steel pipes for manufacturing the structure. The welded line pipe structure allows the prevention of occurrence of SCC under the CO2 circumstance at a high temperature.

Abstract: The invention concerns a welding device and a welding method, in particular of tubular parts (c1, c2) such as abutting metal conduits to form pipeline metal pipes, which consists in effecting the penetrating pass from outside. The invention is characterized in that it consists in creating a single liquid weld metal under the simultaneous action of at least one laser beam (1) transmitted by optical fiber and at least one electric arc protected by gas generated from a consumable electrode (2a) constituting the filler material. The invention is mainly applicable to the construction of pipelines.

Abstract: A laser sensor to scan the weld joint either before welding begins as a pre-weld scanning operation or in real time during welding to provide adaptive control of the arc welding parameters. A "line" type laser sensor device projects a laser line within a fixed operating window. The line laser produces a reflective position of anything that the laser line "sees" within the operating window. By triangulation, the exact distance an object is from the laser can be measured at any point along the "line" of the laser. Certain parts of the weld bevel are targeted for measurement. The measurements are stored in an electronic storage medium and a data processor. The stored measurements and data processor are used in conjunction with automated welding equipment to adjust the welding parameters as required. Because the exact joint/weld geometry is then known for every portion of the weld, the welding equipment can then respond or "adapt" to variations in the weld joint between the work pieces.

Abstract: Provided are a seamless bent pipe constituted by a bent section and straight pipe sections on both ends of the bent section, with the inside diameter at each pipe end portion being larger than the inside diameter of the bent section, and a welded component comprising a seamless bent pipe and a seamless straight pipe at one or each end of the seamless bent pipe, with the end of the seamless straight pipe to be welded to one or each end of the seamless bent pipe having the same inside diameter as the inside diameter of the seamless bent pipe, as well as methods of manufacturing them. As a result, elements suited for use in pipelines can be obtained, without unnecessarily increasing the wall thickness of the seamless bent pipe and without internal machining of the pipe end portions of the seamless bent pipe after the manufacturing thereof.
