Abstract
Description
まず、重ねあわせた鋼板の両側から通電し、必要なナゲット径を確保するための溶融部を形成する。この溶融部形成のための通電は、凝固が始りさえしなければ、どのように選んでもよい。多段通電であってもよい。また、電流値は一定でなくともよく、サイン波やパルス波でもよい。
必要な溶融径の溶融部が形成できたら、それに続いて、溶融径を維持する電流値より低い電流値を通電し、溶融部を凝固させながら電磁振動を印加する。
fV:電磁振動の周波数
νS:凝固速度(凝固界面の進行速度)
λD:デンドライトのアーム間隔
0.2≦A≦4.0 ・・・(2)
Z=CTS/TSS ・・・(4)
CTS:十字引張強さ
TSS:引張せん断強さ
表1に示す鋼板を用意し、表2に示す組み合せで、スポット溶接を行った。溶接条件を、表2に併せて示す。

- 十字引張強さCTSと引張せん断強さTSSの比、CTS/TSSが0.33以上であることを特徴とする請求項1に記載のスポット溶接継手。
- 通電により溶融部を形成する溶融部形成工程と、
上記溶融部形成工程に続いて、上記溶融部形成工程で通電する電流よりも低い電流を通電し上記溶融部を凝固させる凝固工程と
を含み、
上記凝固工程において、上記溶融部に電磁振動を印加し、
上記電気振動電磁振動の周波数fV、上記溶融部が凝固する際の凝固速度νS、及び上記溶融部が凝固する際のデンドライトのアーム間隔λDが、0.2≦νS/(λD・fV)≦4.0を満たす
ことを特徴とするスポット溶接方法。
