Abstract: A method of creating a weld to connect a first element to a second element, said elements being arranged in a wellbore (1) containing a wellbore fluid, is provided. The method comprises selecting a welding path along which the weld is to be created, selecting a volume portion of the wellbore, in which selected volume portion said path is located and sealing said selected volume portion from the remainder of the wellbore volume, and providing pressure control means (12, 16) for controlling the fluid pressure in said selected volume portion. The pressure control means is then operated so as to reduce the fluid pressure in said selected volume portion to a selected pressure at which the weld can be created, and the weld is created along the selected welding path.

Abstract: A ball valve is produced, which has a valve housing 10 and a ball 20. A pair of mirror-symmetrical housing halves 12, 14 are jointed together along a single weld line. The housing halves are jointed together by welding in a manner to enclose the ball previously provided with a through bore and a pair of recessed portions. The through bore 22 of the ball is arranged to be in conformity with the weld line. Holes 42, 50 for respectively mounting a pair of stem assemblies are formed by machining respectively in those portions of the valve housing opposed respectively to open opposite ends of the through bore. The centers of the holes are in alignment with the operational centerline of the ball valve. The ball is turned by an angle of 90 degrees, thereby bringing the through bore of the ball into alignment with openings 12A, 14A of the valve housing, and the recessed portions 26, 28 of the ball are brought into alignment with the holes, respectively. Next, the pair of stem assemblies 60, 68 are attached to the both holes, respectively, and stems are fitted in the both recessed portions, respectively, and the pair of stems are welded circumferentially to peripheral edge portions of the holes, respectively.

Abstract: A method of monitoring the nugget size of the welds produced by a spot welding machine, comprises optically imaging a region of a weld spot onto a transducer (21) after completion of the spot welding process. The transducer (21) produces an electrical signal having a value dependent on the mean intensity and the wavelength distribution of the radiation emitted from the region of the weld spot (18) imaged on to the transducer (21). A computer (24) analyses the electrical signal produced by the transducer (21) to evaluate a weld nugget size indicator value and issue a warning through a visual display module (31) when welds of poor size are being, or about to be produced, so that corrective action can be taken by replacing or dressing the electrodes.

Abstract: A turbine rotor consisting of a wheel made of a TiAl alloy of good heat resistance and a rotor shaft made of a steel with good bonding strength is disclosed. As the shaft material a structural steel or a martensitic heat resistant steel is used. A TiAl turbine wheel made by precision casting is butted to the shaft with insertion of a brazing filler in the butted interfaces and stress of 0.01kgf/mm 2 or higher but lower than yield stress of the shaft is applied on the butted interfaces under heating by high frequency induction heating in atmosphere of an inert gas or a reducing gas to a temperature higher than the liquidus temperature of the brazing metal but not exceeding 100°C above the liquidus temperature. Turbine rotors with good accordance of the axes of the wheel and the shaft will be obtained by fitting a projection (or recess) and a recess (or projection) formed at the base of the wheel and the end of the shaft concentrically to the outer shape thereof, and by brazing the ring-shaped area outside the fitted parts.

Abstract: An apparatus for joining two ring-shaped members (12,13) in stacked relation is disclosed and comprises a jig (28), pressing means (50), drive means (60) and spot welding means (70). The pressing means (50) is configured for urging a first ring-shaped member (12) into contact with a second ring-shaped member (13) held by the jig (28) so that they can be rotated together by the drive means (60) and the spot welding means (70) is configured for tack-welding ring-shaped members (12,13) being rotated by the drive means (60). The apparatus is specifically intended for use in the manufacture of a device for counteracting the imbalance caused by the uneven distribution of laundry in a washing machine drum.
