    Abstract: A method for manufacturing a fuel rod of the present invention includes a welding step of welding a cladding tube of said fuel rod to a plug by arc discharge; and a post welding step of subsequently discharging an arc to a welded portion by a predetermined arc current lower than that of the welding step. In the welding step and in the post welding step, the cladding tube and the plug are rotated with respect to an electrode for discharging the arc. The rotation speed of the cladding tube and the plug in the post welding step is higher than that in the welding step.

    Abstract: A rock drilling rod is manufactured by placing free ends of first and second hollow rod components in abutment, and establishing relative rotation between the free ends to friction weld those free ends together. The first component comprises a thread and a clearance portion disposed adjacent the thread. The first component has a hot hardness value of at least about 170 HV1 at 600.degree. C. Prior to friction welding the components together, the thread, clearance portion and central passage of the first component are heat treated against corrosion fatigue. Then, the thread is high frequency hardened to a depth at least as great as the heat treated layer. Following the welding, the weld is cooled while keeping a core hardness of the respective portions of the first and second components disposed immediately adjacent the weld no lower than 390 HV1.

    Abstract: A space frame includes a pair of laterally spaced, longitudinally extending side rail structures and longitudinally spaced pairs of laterally spaced upright structures having joints at their lower ends with the pair of side rail structures. The longitudinal spaced pairs of laterally spaced upright structures extend upwardly from the side rails structures and define a plurality of pairs of pillars, including a pair of forward A pillars, a longitudinally spaced pair of B pillars, and a longitudinally spaced pair of rearward end pillars. A pair of the side roof structures has joints with the pair of A pillars. The pair of side roof structures extends longitudinally rearwardly from the pair of A pillars and have joints with the pair of B pillars and with the pair of rearward end pillars. Longitudinally spaced cross structures have joints with the pair of side rail structures, with the pair of A pillars and with the pair of side roof structures. A front structural assembly has joints with a forward end of the pair of side rail structures and with the A pillars at positions spaced upwardly of the pair of side rail structures. A plurality of the structures have more than two spaced successive joints which determine defining lengths in the space frame. The plurality of structures comprise a pair of hydroformed tubular members, each of which is defined by an irregularly outwardly deformed tubular metallic wall fixed into a predetermined irregular exterior surface configuration.

    Abstract: A welding apparatus (28) for forming a circumferential weld (56) includes a base (30) and a spindle (32) extending perpendicularly from the base. Along the spindle, at its proximal and distal portions, first and second workpiece supporters (38, 40) are provided, respectively, to position workpieces (42) to be welded together therebetween. Between the first and second workpiece supporters, a first arm (44) and a second arm (48) are provided, both extending perpendicularly from the spindle. To a distal end of the first arm, an internal backup roller (46) is rotatably attached, and to a distal end of the second arm, an internal drive roller (50) is rotatably attached. One or more external rollers (52a, 52b), each rotatably attached to an external support (66), are further provided. The internal and external rollers are driven by variable-speed programmable motors (not shown). In operation, the workpieces are mounted onto the apparatus, being sandwiched between the internal rollers and the external rollers. A friction stir welding tool (58) is positioned externally with its probe opposing the internal backup roller. As the programmable motors drive the rollers to continuously draw the workpieces between the friction stir welding tool and the internal backup roller, the friction stir welding tool forms a circumferential weld to join the workpieces together.

    Abstract translation: 用于形成圆周焊缝（56）的焊接装置（28）包括基部（30）和从基部垂直延伸的主轴（32）。 沿着主轴，在其近端和远端部分分别设置有第一和第二工件支撑件（38,40），以将待焊接在一起的工件（42）定位。 在第一和第二工件支撑件之间，设置有从主轴垂直延伸的第一臂（44）和第二臂（48）。 在第一臂的远端，可旋转地安装有内部支承辊（46），并且在第二臂的远端可旋转地安装有内部驱动辊（50）。 还设置有一个或多个可旋转地连接到外部支撑件（66）的外部辊（52a，52b）。 内部和外部辊由可变速可编程电机（未示出）驱动。 在操作中，工件被安装到设备上，夹在内部辊和外部辊之间。 摩擦搅拌焊接工具（58）位于外部，其探针与内部支撑辊相对。 由于可编程电机驱动辊子以将工件在摩擦搅拌焊接工具和内部支撑辊之间连续地拉伸，所以摩擦搅拌焊接工具形成周向焊缝以将工件连接在一起。
