摘要： Method for connecting an electrical conductor (17) to a metal bar (11) by bolted connection, whereby a bushing (10) provided with a collar (12) is inserted into, and is by radial expansion fastened in, a hole in the metal bar, a cable lug (16) connected to the electrical conductor is caused to abut against the bushing, and the cable lug is connected to the bushing by means of a bolt (14) disposed in the bushing and forming part of the bolted connection. An expansion device (23) with a threaded portion (26) and an expansion collar (25) is drawn through the bushing in order to expand the latter. A fitting nut (20) with a thread (21) cooperating with the threaded portion (26) is rotated in abutment against the collar (12) of the bushing in order to draw the expansion tool through the bushing. The expansion device (23) with the fitting nut (20) is removed from the bushing, a bolt is inserted through the bushing and a tapered clamp ring (13) surrounding the bolt and abutting against a head (15) of the bolt is pressed into the bushing during radial widening of the bushing and radial constriction of the clamp ring round the bolt as a result of tightening of the bolted connection. Bolted connection, comprising the bushing (10) and a bolt (14) provided with a head (15) and inserted through the bushing, whereby the length of the bushing exceeds the length of a hole formed for the bolted connection in a metal bar. A tapered clamp ring (13) is disposed about the bolt at the head of the bolt. The tapered clamp ring is pressed into the bushing between the bushing and the bolt, and the collar of the bushing has an unengaged flat annular surface. A tool for fastening the bushing comprises an elongate expansion device (23) and a fitting nut (20) cooperating with the expansion device (23). The expansion device (23) is provided with a threaded portion (26) at a first end and a tool spigot (24) at a second end and is provided between said portions with an expansion collar (24) with circumference increasing from the threaded portion (26).

摘要： An apparatus for brazing a connecting piece of electrically conducting material such as metal, to a metal surface by means of a new type of temperature-controlled brazing whereby for certain types of material a brazing is obtained that is free of martensite formation underneath the brazed joint in, for example, railway track and/or pipework. The apparatus has an electrode and processing circuitry by which a voltage applied in electrical circuit with the electrode causes an electric arc to be struck between the electrode and an adjacent workpiece to generate the heat necessary for brazing.
