接する方法が知られている。As another method, a dish-shaped disk 23 is provided at the tip of one side of a thin metal rod 21 as shown in FIG.
Some use a flange 24 which is thicker than the metal bar 21 at multiple ends, and a countersink pin 2 having a navel-shaped small projection 22 on the end surface of the flange 24. First, the coating material 3 is put on the base material 4 of the duct, and then a guide hole is made in the coating material 3 with a screwdriver or the like, and the flat pin 21 is inserted into the guide hole while the flat pin 21 is attracted to the magnet of the welding gun. Is press-contacted to the base material 4 and a stud welding is performed between the navel-shaped small protrusion 22 side and the base material 4.

らに高くなり、施工コストが割高となる。In the former method, it takes time to apply the adhesive, and a predetermined time is required for drying the adhesive. In the latter method, the countersunk pin 2 having the small projections 22 and the flanges 24 at the tips thereof has a high manufacturing cost and a high construction cost. In addition, it is difficult to insert the countersink pin 2 unless a guide hole is provided in the coating material 3. In addition, in the case of applying the lower surface of the duct, the coating material 3 must be attached to the base material 4 by some means before welding. At this time, since the tip of the countersink pin 2 is hidden by the covering material 3 and cannot be seen, the countersink cannot be perpendicularly welded to the base material 4 of the duct without considerable skill, and the welding strength is extremely reduced.
In addition, since arc welding is performed around the coating material 3,
The covering 3 must be a non-combustible material. In addition, when the covering material 3 is covered with aluminum foil, it is necessary to apply an electrically insulating coating to the countersink pin 2, so that the manufacturing cost of the countersink pin 2 is further increased and the construction cost is relatively high.

Therefore, after inserting the covering material 3 into the standing pins 5, it is necessary to bend the round bar portion 51 protruding from the covering material 3, and the brass round bar 51 is employed to provide flexibility. . The material of the round bar 51 is selected from soft iron, stainless steel, copper, brass, aluminum, and the like according to the type of metal of the base metal to be welded and the method of surface treatment of the metal.

ナイフ状に尖鋭化したものでもよい。The diameter of the round bar 51 varies depending on the weight and thickness of the coating material 3, but is about 1 to 3 mm. The tip angles at both ends are suitably about 30 to 120 °, and most preferably 45 to 90 °. If the tip angle is less than 30 °, machining becomes difficult, the tip is likely to bend when pressed against the base material, and the thin part of the tip melts early due to the welding current. A large gap is generated, so that the welding is incomplete and strong welding cannot be expected. Tip angle is 1
If it exceeds 20 °, a large welding current is required. Round bar 51
Is about 30 to 150 mm, and is appropriately selected depending on the thickness of the coating material 3. If the tip angles of both ends of the round bar 51 are the same, either side can be used for the side to be welded. In addition to the conical shape, the tip of the round bar 51 may have a pyramid shape like a four-pointed or three-pointed tip, or may have a sharpened knife-like shape.

Around one, three leg bars 62 are provided at equal intervals on a circumference centered on the chuck 61 position, and one ground bar 63 is provided inside the circumference. . When the tips of the three legs 62 are brought into contact with the base material 4, the pins 5 mounted on the chuck 61 are positioned perpendicular to the base material 4, and 4 with a force of about 1 kg.
Similarly, the tip 64 of the ground rod 63 is also about 1

The periphery is melted, and the pin 5 is welded to the base material 4 by the pressing force. When the welding is completed and the welding gun 6 is separated from the base material 4, the pins 5 are firmly erected on the base material 4. Then, the covering material 3 is pushed in from the sharpened other end of the pin 5 and a washer 13 is fitted to a portion of the pin 5 protruding from the covering material 3, and the portion is bent as shown by a two-dot chain line in FIG. The coating material 3 is attached to the base material 4 of the duct.
