摘要： PROBLEM TO BE SOLVED: To prevent a steel core wire (element wire with steel core) from spreading outward caused by the reaction heat when being jointed. SOLUTION: The ends of steel-core aluminum electric wire 50 are coupled together via a welded part so that a joining structure of electric wires 50 is accomplished, wherein the two ends are fitted with restraining rings 60 made of a material having a melting point over the temp. of the welded part. According to this welding method for steel-core aluminum wires, in which the ends of the wires 50 are inserted in a welder and coupled together through the welded part, the restraining rings 60 installed at the two ends prior to welding prevent the core wires of steel from spreading at welding.

摘要： PURPOSE:To accumulate a heated molten material in a basin, and utilize the molten metal when cooled to prevent the generation of an indentation or cavity. CONSTITUTION:End parts 13a of aluminium wires 13 having molten metal stopping metal fittings 14 are inserted from both sides of a housing part 1, and brought into contact with an aluminium welding material 12. The ignition tool 7 of the housing part 1 filled with a heating agent 9 is operated, and the heat of oxidation reduction reaction of the agent 9 is added to the material 12 through a bulkhead member 3 to melt it. The molten material 12 is passed through a communicating part 17 and accumulated in a basin part 15. The outflow of the molten aluminium to the outside is arrested by the member 3 and the stopping tool 14 in the position of the molten metal stopping tool 14. When the heating is finished, the fused part starts coagulating and contracting. The molten material stored in the basin part 15 flows into a recessed part or cavity part in the contracted part of the fused part, so that the generation of an indentation or cavity can be prevented.

摘要： PURPOSE: To provide the joining method for joining electric cables not by mechanical compression or squeezing effects but by a metallurgical junction joining not only the part exposed outside of the stranded cables but also their inner layer parts without giving any damage to the cables, when stranded cables made of aluminum or its alloys used as transmission and distribution lines, stranded cables made of copper or its alloys, aluminum cables steel reinforced (ACSR) and the like, are joined by making use of explosion pressure. CONSTITUTION: This invention is concerned with a joining method where a protective body which is made of metal identical to the material of the outer layers of stranded cables, is formed into a pipelike curved surface in advance, is covered over the outer circumference of the cables to be joined, a flying body is disposed at the outer side of the protective body which is made of metal identical to the material of the protective body, and flies in by the explosion pressure of explosives so as to be hit against the protective body, and the flying body, the protective body and the cables are thereby metallurgically and integrally joined. The explosives are set in such a way as to enclose a flying tube, let the explosives progress from one end of the explosives to the other end progressively. It is so designed that the progressing speed of explosion (explosion speed) is less than 70% of the sound speed of the metal for the outer layers of the cables to be joined, and the flying speed of the flying tube in the direction perpendicularly intersected with the progressing direction of explosion, is sufficient enough to join the stranded cable themseves in the inner layer.
