【発明が解決しようとする課題】これは次のような問題
点があった。通常の位置決めのスカートを設けただけの
ナットサートは、ゴミその他不純物が付着している場合

険が増す。本発明は、これらの問題点を除くためになさ
れたものである。This has the following problems. A nutsert having only a regular positioning skirt has a risk that spot welding defects easily occur when dust or other impurities are attached, and there is a risk of falling off when welding is defective. Further, when the material is a nutsert such as an aluminum alloy, the risk of falling off due to poor welding increases. The present invention has been made to eliminate these problems.

ナットサート用スポットチップ。According to the present invention, a spot tip B (2) is connected to a pressurized horn (5), and the inside thereof is moved up and down to form a caulked skirt (6) with a caulked skirt. An insulating press bar (3) and an elastic spring body (4), which are squeezed and pressed against the skirt (7), are provided and mounted. The present invention provides a spot tip for nutsert with a caulking skirt having the above configuration.

With the power of the spot welding machine turned on, the spot tip A (1) and the spot tip B (2) are respectively sandwiched from above and below the nut sert (6) with a caulking skirt by the compressive force of the pressurizing horn (5), and pressed. A current is applied to perform spotting. Then, the crimped skirt (7) softened by the heat of the spot welding is spread by the insulating press bar (3) with the pressing force (F) using the cushion of the elastic spring body (4) while being sandwiched as it is. It is swaged. After this, the upper and lower pressurized horns (5) are retracted, and the nutsert with crimped skirt (6)
Is firmly attached to the processing plate (8).
