摘要： PURPOSE:To prevent mixing of impurities and run-off of a welding material in a heating and welding work, by inserting the ends of electric wires by holding a welding material in a housing, installing molten metal stoppers to the ends of the electric wires, and filling a heating agent through a partition wall member. CONSTITUTION:In a housing 1 which consists of a cartridge outer tube 2, a partition wall member 3, and end plates 4, a heating agent 5 and an aluminum welding material 7 are filled. Two aluminum electric wires 8 in which molten metal stoppers 9 which consist of a heat resisting ceramic film are formed at the wire ends are inserted into the housing 1, and their tips are abutted to the welding material 7. Then, by reacting the lighting agent 5 by an igniter 6, the welding material 7 is melted by the oxidizing and reducing reaction heat. The welded aluminum flows out on the surface of the electric wires 8, but the run-off to the outer side is blocked by the stoppers 9. After the aluminum is cooled and solidified, the electric wires 8 are picked up. Consequently, the mixing of impurities and the run-off of the welding material in the heating and welding work can be prevented.

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.
