Abstract:
A method and related apparatus for precision deploy-attaching beam-mount structure to the outside of an elongate column at plural, defined attachment sites that are distributed and spaced along the length of the column. The method involves (a) preparing an elongate column to act as a travel way for a carriage which is designed to transport and deploy beam-mount structure, shifting such a carriage progressively along the column from defined attachment site to defined attachment site, and at each such site, deploy-attaching from the carriage to the column the carriage-carried beam-mount structure.
Abstract:
The invention relates to an apparatus for cutting workpieces (W), in particular elongated workpieces (W), such as tubular members and beams. The apparatus comprises a support (1) for supporting the workpiece, a frame (3) and a circular guide on the frame, on which a carrier (13) is mounted. The carrier is provided with a controllable driving mechanism, wherein said carrier (13) and said support (1) are so positioned relative to each other that the workpiece extends through the guide during the cutting operation. A cutting element (11) is connected to said carrier. A control unit (8) controls the carrier. The cutting element (11) is connected to the carrier (13) via a robot arm (12), which is mounted on the carrier, whereas the control unit (8) is furthermore arranged for controlling the robot arm (12). The invention furthermore relates to a method for cutting workpieces.
Abstract:
The clad material comprises outer layers each consisting of Ni or Ni alloy and a base layer consisting of Cu or Cu alloy, and is characterized in that peeling-off at a clad boundary is not recognized in cross section observation made after the clad material has been subjected to a 90° reverse bend test ten times, and the number of reverse bend cycles before rupture is 17 cycles or more. The clad material has with both of excellent corrosion resistance against electrolytic solution and high electric conductivity.
