Problems solved by technology

In the spot welding performed in the above state, the resistance heat generated when the materials on both sides and the welding auxiliary parts are in the energized state is transmitted to the dissimilar materials in a direct contact state, and there are cases where the dissimilar materials are damaged due to fire, etc., or to the dissimilar materials. In the case of material conduction, there is a problem of reduced welding quality

Embodiment Construction

[0039] Next, for the embodiments of the welding auxiliary parts according to the present invention, while referring to the attached Figure 1 Explain in detail.

[0040] figure 1 The structure of the welding auxiliary part 10 according to the embodiment of the present invention is shown, the figure (A) is a perspective view seen from above, and the figure (B) is a cross-sectional view in the thickness direction. In the present embodiment, the welding auxiliary member 10 is composed of a substantially disk-shaped main body 10a and a foam material 10b attached to the outer surface of the main body 10a as a position holding part. The main body portion 10a is made of a conductive material, for example, a metal material mainly composed of iron or the like. In this embodiment, the first materials 12-1 and 12-2 are made of the same material. In this embodiment, the outer diameter of the main body part 10a is shown as about 10 mm. In addition, the thickness of the main body portio...

Abstract

A welding assistance member with electrically-conductive properties is used for spot-welding performed by sandwiching a second member between electrically-conductive first members different in material from the second member. The welding assistance member is fitted into a hole extending through the second member so as to allow for spot-welding of the first members to each other from opposite sides in the hole. The welding assistance member includes: a main body that has a size and shape that allow a gap to be formed between the main body and an inner side surface of the hole when the main body is fitted in the hole; and a position maintaining component that is provided at an outer side of the main body, has heat, heat resisting, and electrically insulating properties, and maintains the main body in a separated state from the inner side surface. A spot-welding method uses this welding assistance member.

Description

technical field [0001] The present invention relates to a welding auxiliary part and a spot welding method using the welding auxiliary part, and in particular, relates to a welding auxiliary part used when fully utilizing spot welding to join dissimilar materials and spot welding using the welding auxiliary part method. Background technique [0002] It is known that when spot welding a dissimilar material is sandwiched between two conductive materials, a hole is formed through the dissimilar material, and the same material as that of the materials on both sides is filled in the hole. The welding auxiliary part made of conductive material is spot-welded from both sides of the hole. [0003] In such spot welding, the hole in which the welding auxiliary component is loaded is sandwiched by conductive materials on both sides, and the loading state of the welding auxiliary component installed in the hole, that is, the loading position cannot be confirmed. Therefore, if the weld...
