が本発明である。(b) Conventional technology Conventionally, manual arc welding using high current using a low-hydrogen welding rod has been carried out for this technical purpose. As other welding methods, fillet welding and hole fillet welding have been used, but they had various difficulties and were not put into practical use. Therefore, the inventor applied for a patent application in 1983-
The present invention was realized using No. 117153, but is further improved.

点、が重要である。(C) Problems to be Solved by the Invention The previous invention has put into practical use the welding of deck plates to steel beams by gas arc spot welding by devising a special nozzle. It is important to prevent spatter a from adhering to the inner surface, and to keep the amount of spatter a small even if it adheres, or to make it easy to remove.

る。(d) Means, actions, and examples for solving the problem Steel beams are usually coated, and deck plates are galvanized or coated on one side. When welding onto a steel beam using arc spot welding from the deck plate under these conditions, with a conventional nozzle, a large amount of spatter adheres to the inner surface of the nozzle, making it impossible to proceed with welding even after welding a few points. There are cases. In other words, the conventional type
If the nozzle hole in Figure c is clogged with spatter and the amount of spatter increases further, arcing will occur directly on the nozzle and the inner surface of the cap, damaging the nozzle. Also, arcing will occur directly on the inside of the cap, causing damage to the cap. Furthermore, spatter adhering to the inner surface of the nozzle is strong and difficult to remove because the nozzle overheats. As described above, workability becomes extremely poor.
この為本発明はノズル体を改良した。 For this reason, the present invention has improved the nozzle body.
即ち本発明ノズル体は市販ノズル４にセツトし

ー３を張り出して成るキヤツプ１をノズル４にカ
ラ内孔部で嵌合させて位置決めをし、ビス２で締
付け固定するという解決手段を採用した。 That is, the nozzle body of the present invention is used by being set in a commercially available nozzle 4, and the cap 1, which has an opening 5 in the upper part, an appropriate number of blowholes 6 at the lower end, and a collar 3 projecting from the upper end, is attached to the nozzle 4. A solution was adopted in which the two parts were fitted into each other using the inner hole of the collar to determine the position, and then tightened and fixed with screws 2.
この様な手段は次の如き作用をなす。 Such means have the following effect.
キヤツプ１とノズル４との間は空洞となり、溶
接時にパイプ内で生じたヒユームガスは主として

孔位置もカラー３位置まで大きく開口してもよ
い。噴気孔６はスパツター除去の役割をするが、
孔が大き過ぎると風の影響を受けるので小さく開
口する。 There is a cavity between the cap 1 and the nozzle 4, and the fume gas generated in the pipe during welding mainly passes through the cavity and exits through the opening 5, thereby discharging heat within the cap and preventing the cap from overheating. do. The effect is greater as the opening 5 is located at the upper part of the cap 1, and the shape of the hole may be any shape.
The hole position may also be wide open up to the collar 3 position. The fumarole 6 has the role of removing spatter,
If the hole is too large, it will be affected by the wind, so it should be opened small.
カラー３はキヤツプ径に比べて大きい径のカラ
ー３を有している。第１図に示すように溶接者の
眼に直接アークの影響が入らない様に保護してい
る。 The collar 3 has a diameter larger than the cap diameter. As shown in Figure 1, the welder's eyes are protected from direct arc effects.

るものである。(E) Effects of the Invention As mentioned above, special measures have been taken to discharge and remove spatter, making it possible to perform arc spot welding on several dozen points in succession, and reducing nozzle burnout.
The adhesion of spatter to the inner surface of the nozzle is reduced, and its removal becomes easy and simple, resulting in a marked improvement in work efficiency.
