Abstract: Tubular ends are heated to a predetermined temperature above 1200 degrees Celsius and surrounded by a shield gas when the tubular ends are pressed together to form forge welded tubular ends. The forge welded tubular ends are then cooled down rapidly from said temperature above 1200 to at most 600 degrees Celsius within 3 minutes after the forge welding operation.
Abstract translation: 将管状端部加热到高于1200摄氏度的预定温度，并且当管状端部被压在一起以形成锻造焊接的管状端时，被保护气体包围。 锻造焊接的管状端部在锻造焊接操作后3分钟内迅速地从1200℃以上的温度冷却至至多600摄氏度。

Abstract: A method of joining tubulars includes the step of joining the tubulars by forge welding. The tubular ends that are to be welded together may be shaped into a sloping configuration, such that when the tubular ends are heated during the forge welding process the heated tubular ends deform as a result of thermal expansion into a substantially longitudinally oriented cylindrical shape.
Abstract translation: 连接管的方法包括通过锻造焊接连接管的步骤。 要焊接在一起的管状端部可以成形为倾斜构造，使得当在锻造焊接过程期间管状端部被加热时，由于热膨胀成基本上纵向取向的圆柱形状，加热的管状端部变形。

Abstract: A method of joining heavy duty oilfield, well, or other tubulars includes the step of joining the tubulars by forge welding and flushing a reducing flushing gas around the heated tubular ends during at least part of the forge welding operation such that oxides are removed from the forge welded tubular ends and the amount of oxide inclusions and irregularities between the forge welded tubular ends is limited. The tubular ends may have a teethed sinusoidal or other non-planar shape to inhibit any abrupt variations of the wall strength in the welding area and/or to reduce shear forces to the forge weld when the tubulars are twisted and/or radially expanded.
Abstract translation: 连接重型油田，井或其他管道的方法包括在至少部分锻造焊接操作期间通过锻造焊接和冲洗加热的管状端部周围的还原冲洗气体来连接管件的步骤，使得氧化物从 锻造焊接的管状端部，并且锻造焊接的管状端部之间的氧化物夹杂物和不规则性的量受到限制。 管状端部可以具有尖端的正弦曲线或其他非平面形状，以防止焊接区域中的壁强度的任何突然变化和/或当管状物被扭曲和/或径向膨胀时减小对锻造焊缝的剪切力。

Abstract: A method for inspecting welds between welded tubular ends includes arranging a series electromagnetic acoustic transducer (EMAT) assemblies in circumferential direction adjacent to an inner and/or outer surface of at least one of the welded tubular ends and inducing the EMAT assemblies to transmit sequentially or simultaneously acoustic shear wave signals towards the weld and to detect the shear waves reflected by and/or passing through the weld while the EMAT assemblies are maintained in a substantially fixed position relative to the weld such that at least a substantial part of the weld is scanned by the EMAT assemblies instantly after the weld is made.
Abstract translation: 用于检查焊接的管状端部之间的焊缝的方法包括在邻近焊接的管状端部中的至少一个的内表面和/或外表面的周向方向上布置串联电磁声换能器（EMAT）组件，并且引导EMAT组件依次或 同时声波剪切波信号朝向焊缝并且检测由焊缝反射和/或通过焊缝的剪切波，同时EMAT组件相对于焊缝保持在基本上固定的位置，使得至少大部分焊缝被扫描 在焊接后立即由EMAT组件。
