た。2. Description of the Related Art Conventionally, in the case of laterally stud welding a stud to a steel wall, unlike the downward stud welding, the diameter of a stud that can be welded without defects is at most about 20 mm. In the case of stud welding, the welding needs to be performed by supplying a large current exceeding 2000 A, the amount of molten metal increases as the diameter of the stud increases, and the molten metal is laterally oriented, resulting in uneven thickness. However, there is a problem in that the stud cannot be welded to the steel wall reliably and stably by dropping or dropping.

にある。According to the present invention, when a steel stud is laterally welded to a steel wall, the end surface of the stud to be welded is cut out to form an inclined groove, and the inclined groove is formed. Stud welding in a horizontal direction in advance except for the inclined groove portion, and then insert a steel backing plate made up of a cylindrical portion and a U-shaped portion into the inclined groove portion of the stud to form a steel wall. The stud inclined groove portion and the U-shaped portion of the backing metal form a groove portion having an open upper portion, and are welded downward by covered arc welding, gas shielded arc welding or no gas arc welding, and the backing metal is welded. It is a lateral welding method for large diameter studs, which is characterized in that it is a part of steel studs.

FIG. 1 shows a large-diameter stud having a diameter of 25 mm or more used in the present invention, 1 is a stud main body, 2 is an inclined groove provided on the end surface of the stud, and 3 is a stud welding surface having an area that can be stud welded by a conventional technique. This area is 31
If the inclined groove is formed so as not to exceed 5 mm 2 , lateral stud welding can be reliably performed by the conventional technique.

Figure 3 shows a steel backing plate 6 consisting of a cylindrical part and a U-shaped part.
A groove 7 is provided on the end surface of the U-shaped portion of this backing metal, and when this is fitted into the stud already welded to the steel wall as shown in FIG. Prevents interference with the wall.

It shows the situation in which is formed. Since the backing metal has a cylindrical portion, it can be set by inserting it into a stud welded sideways, so that molten metal does not flow down and tack welding is not necessary.

る。As described above, according to the present invention, even if the diameter of the stud is increased, the stud tip is obliquely removed to the area where the stud welding can be performed by the conventional technique, and the stud welding is performed.
Since the space surrounded by the backing metal is arc-welded in a downward position that facilitates welding work, there is no problem of molten metal dripping, and the backing metal itself becomes part of the stud. The strength of can also be reinforced, and a large-diameter stud can be easily welded laterally to the steel wall.
