てリードインワイヤを得ている。[Prior Art] Generally, incandescent lamps use Dimet wire as a sealing wire with the stem tube, but since halogen lamps have a higher temperature than incandescent lamps, a wire made of a high-melting point metal such as molybdenum is sealed. It is used as a line. Therefore, when forming a lead-in wire for a halogen lamp by joining a sealed wire made of a high-melting-point metal to an outer lead wire made of nickel, etc., it is necessary to bond the sealed wire cut to a predetermined length and the outer lead wire. The lead-in wire is obtained by butting the lead-in wire and joining it by resistance welding.

In the figure, 1 is a sealed wire, and 2 is an outer lead wire, and these sealed wire 1 and outer lead wire 2 are held by chucks 3 and 4 with their tips facing each other.

ターリード線２に交流電流を通電する。When joining the sealed wire 1 and the outer lead wire 2 in the above-described configuration, first the chucks 3 and 4 are brought close to each other by a drive mechanism (not shown), and the chucks 3 and 4 are connected to each other as shown in FIG. The held sealed wire 1 and outer lead wire 2 are butted against each other. Next, hydrogen gas is ejected from the hydrogen ejection nozzle 7 to the abutting portion of the sealing wire 1 and the outer lead wire 2, and an alternating current is applied to the sealing wire 1 and the outer lead wire 2 from the welding transformer 5.

The Joule heat generated melts the sealing wire 1 and the outer lead wire 2, and the sealing wire 1 and the outer lead wire 2 are welded and joined. At this time, since hydrogen gas is ejected from the hydrogen ejection nozzle 7 to the butt portion of the sealing wire 1 and the outer lead wire 2, oxidation of the molten metal can be prevented by the reducing action of the hydrogen gas.
