。[Problem to be solved by Kouko] Regardless of which method is adopted, when welding, the end surfaces of the metal to be welded should be brought close to each other, and an appropriate distance should be formed depending on the thickness of the material to be welded. (In some cases, a 7-shaped or X-shaped groove is formed in the welded part), it is necessary to melt the filler 2 Al in small amounts by using an arc from a welding torch or a plasma jet to suit the welding process. For this reason, it goes without saying that when performing manual welding, that is, supplying filler while observing the formation status of the weld, the welding operator is required to have an extremely high level of skill. Even if welding is actually maintained while supplying welding, there are many variables that vary, such as the adjustment of the t-flow at that time, and it requires a high degree of skill to achieve welding that is both visually pleasing and metallurgically perfect. . Therefore, automatic welding equipment that is configured to supply filler by adjusting the supply speed using an automatic feeder has been put into practical use, but it is also possible to adjust the setting conditions of the nozzle voltage and current. Very difficult conditions such as the installation position of the 7B welding device and the insertion angle of the filler must be optimally set, and even if such automatic welding equipment is used, the supply of filler may not be smooth depending on the setting conditions. However, the welding results may not always be satisfactory.

The purpose of the present invention is to provide a new filler and a welding method that can always form a sound and highly reliable weld by using such a filler.

The first gist is a filler in which a protruding part formed with a height that provides a sufficient penetration is made to protrude continuously in the longitudinal direction of the filler from the flat part that creates heat in a slightly 'I' shape. The protruding part of the filler with a slightly T-shaped cross section configured as above is inserted from the beginning along the entire length between the joint end faces of the welded part, and the open end surface of the welded part is inserted into the protruding part of the T-shaped filler. to ensure that there is no extra gap between the filler and the material to be welded,
Thus, the flat part fi! of the filler is removed by the welding torch. The second gist is to melt a portion of the filler and the metal to be welded from II and move the torch in this manner to weld the two metals.

先を形成しなりすることは先に説明した通りである。Butt welding using such an I-shaped groove is performed when the plate thickness is 1 to 3.
It is relatively frequently used when welding materials of the size of steel. However, as described above, this groove may be formed as a V-shaped groove or an X-shaped groove depending on the thickness of the materials to be butt welded.

Regarding the width W of the flat part 2b, the thickness l, etc., it is better to decide the cross-sectional shape by considering the welded part to be formed. In this case, the thickness 11 of the flat portion 2b may be increased, and if such extra thickness is not required so much, the thickness 17 t2 of the protruding portion 2a may be increased.

Welding was performed using n. As a result, the appearance of the heat after welding was well-ordered and had a good appearance, and when the cross section of the weld was observed using a microscopic structure, the crystals in the weld were extremely fine, and there was no complete contact with the material to be welded. It was possible to form an excellent welded area with the melting being completely fixed.

Since welding is performed in a fixed state, the filler does not move or wobble during welding, so there is no risk of disturbances in the welding state, and not only the appearance of the welded part is extremely stable. The cross-sectional area of the filler to be supplied can be selected in advance so as to have an appropriate cross-sectional area, so the amount of filler is always quantified over the entire length of the weld, and constant heating is performed in such a quantified state. Since the welding condition of the welded part performed according to the present invention can be always selected to be optimal for welding, it is possible to exhibit the excellent characteristics of obtaining.
