をもたらす危険が多いためであった。Although the TIG welding method has a stable arc and extremely good welded joint performance compared to MIG welding,
There are almost no examples of development related to narrow gap welding. This is because the TIGf # welding is inefficient because the filler wire is supplied from the outside, and the melting efficiency of the wire is low and it is difficult to swing the arc in the width direction within a narrow gap. This was because multi-pass welding had to be used, and there was a high risk of instability due to penetration of the groove wall surface.

に詳述すれに次のとおりである。The present invention solves the shortcomings of the conventional technology in TIG welding, and its characteristics are that the electrode and filler metal are each made into a band shape, and the arc is opened by applying an alternating magnetic field in the tangential direction of the arc KII. This invention provides a narrow gap TIG welding method that enables effective swinging in the width direction of the tip. Embodiments of the present invention will be described in detail below with reference to the drawings.

A cooling water tube 5 for circulating cooling water is housed in the housing, and the cooling water cools the electrode nozzle 2 and the electrode 4 to a desired temperature. Gas shield nozzles 6.7 are arranged on both sides of the electrode nozzle 2, and these are fitted into the nozzle holder 1 and are configured to be supplied with shielding gas (for example, Ar) to shield arcs and molten metal. It becomes. A flat filler nozzle 8 is attached to the gas shield nozzle 6, and this filler nozzle 8 passes the band-shaped filler metal 10 fed by the feed motor 9 into an arc 11 generated from the band electrode 4. Guide to nearby areas. On the other hand, a magnetic core 12 passes through the gas shield nozzle 7, and one end is connected to the magnetic pole of an electromagnetic coil 16. The electromagnetic coil 16 has a direct current power source 14 connected to the direction switch 1 using a transistor circuit.
5 to generate an alternating magnetic field. The maximum frequency of the direction switch 14 is 1KH3
It is possible to some extent. The tip of the magnetic core 12 extends to the vicinity of the arc 11, and is placed at an angular position such that an alternating magnetic field is applied to the arc 11 in the direction of the welding line. On the right side is the #welt bead 17, and on the left side is the groove bottom 18 which has not yet been bath welded.
