The second alloy layer is laminated on the first alloy layer, and formed by using a compound represented by the following general formula (1) as a principal component. The second alloy layer is configured to undergo phase transition between a reset phase and a set phase. Electric polarization is not caused in the reset phase, but caused in the set phase.

  • Publication number: 20180043452
    Abstract: A pipe assembly station for performing operations on a field joint during pipe assembly has an active rail extending around an opening through which the pipe can pass. Tool carriages are arranged to traverse along the active rail and around a periphery of the pipe. The station also comprises a standby position, distanced from the active rail and a switch arranged to transfer the tool carriage from the active rail to the standby position. By providing such a combination of a rail and a standby position, a tool carriage can be brought into position on the active rail to perform a pipe joining operation and can be subsequently set back to the standby position, where it is out of the way of operations taking place on the pipe. Such a switching arrangement allows for more effective use of the limited space around the joint.

    Abstract: The present disclosure is directed to a component of a welding device that is configured to produce a shielding gas having a developed flow profile, which provides for a shielding gas column having a laminar profile over a greater length than has been achieved through conventional means. The component utilizes one or more flow restrictors, which are configured to provide higher resistance to the flow of shielding gas at increasing distances from the center of a shielding gas flow channel. By providing increasing resistance toward the periphery of the channel, a developed shielding gas flow profile may be achieved over a relatively short flow length.
