摘要： An offset correction controller in a continuous tack welding machine of the present invention constrains a cylindrical steel plate using a plurality of cage rolls, butts edges in the width direction of the steel plate, and continuously performs tack welding. The offset correction controller includes a detection unit that detects an offset amount between the edges in the width direction of a butted portion of the steel plate, and an offset correction control unit that adjusts constraining forces of the cage rolls arranged on both sides of the butted portion such that the offset amount becomes smaller than a certain value when the offset amount detected by the detection unit is equal to or larger than the certain value, and reduces the constraining forces of other cage rolls when the offset amount does not become smaller than the certain value after the adjustment of the constraining forces of the cage rolls arranged on both sides of the butted portion.

摘要： The invention relates to a method for producing a multi-layer large pipe, which has an outer carrier layer (1) and at least one inner application layer (2). Advantages regarding productivity and properties of the multi-layer large pipe are achieved by the sequence of the following method steps: - providing a carrier sheet for the carrier layer (1), which carrier sheet is pre-bent to a predetermined initial bending radius (RBO), and at least one application sheet for the application layer (2), which application sheet is pre-bent to a predetermined initial bending radius (RAO); - applying the at least one pre-bent application sheet to the inside of the pre-bent carrier sheet in order to form the carrier layer (1) and the at least one application layer (2), wherein the longitudinal edges of the pre-bent application sheet extending in the direction of the bending axis are positioned and oriented in parallel; - connecting at least the two longitudinal edges (3a, 3b, 3c, 3d) of the at least one application sheet to the carrier sheet in a bonded manner; - shaping the composite of the carrier layer (1) and at least one application layer (2) connected in a bonded manner into a slotted multi-layer large pipe by means of a bending machine, wherein contact regions not connected in a bonded manner are connected in a force-closed manner; - closing the remaining gap of the slotted multi-layer large pipe with a longitudinal seam by welding.

摘要： There is provided a combination welding method performed by leading with a tungsten arc welding method and following with a submerged arc welding method by keeping a predetermined separation distance from the tungsten arc weld zone. According to the combination welding method of the present invention, the occurrence of bending of a steel pipe is reduced and a welding time is shortened since the inside welding and the outside welding are simultaneously performed by keeping the predetermined separation distance. In addition, since the outside welding is performed before a fusion area temperature is below an A1 transformation point after the inside welding, the bending of the steel pipe is properly controlled after the welding and therefore straightening time in a post-process is shortened.

摘要翻译：提供了一种通过以钨电弧焊接方法前进并通过保持与钨电弧焊接区域的预定分隔距离的埋弧焊接方法进行的组合焊接方法。根据本发明的组合焊接方法，由于通过保持预定间隔距离同时进行内侧焊接和外部焊接，钢管的弯曲发生减少，焊接时间缩短。此外，由于在内部焊接之后，在熔融区域温度低于A1相变点之前进行外部焊接，所以在焊接之后适当地控制钢管的弯曲，因此后处理中的矫直时间缩短。

摘要： An exhaust gas purification apparatus includes a SCR converter selectively reducing and purifying NOx in exhaust gas upon being supplied with ammonia generated from urea aqueous solution and an injection nozzle injection-supplying the urea aqueous solution on exhaust gas upstream side of the SCR converter. At least a part of an exhaust pipe located between the injection nozzle and the SCR converter has a double-pipe structure including inner and outer pipes, each having a welded portion, and the welded portion of the outer pipe was welded from an inside of the outer pipe. Thus, the outer pipe has fine welded portion on an inner peripheral surface where a welding temperature is high and the coarse welded portion on an outer peripheral surface where the welding temperature is low, resulting in an ordered atomic arrangement and thus improved corrosion resistance of the inner peripheral surface, which may be exposed to ammonia.
