Description
絶縁材料で構成された絶縁筒内に断面円形の細長い部材で形成された電極が電極軸線方向に摺動可能な状態で挿入され、
電極の端面に形成されている押圧面が絶縁筒の端面に形成されている絶縁端面よりも後退した箇所に位置づけられていることにより、押圧面と絶縁筒の内面が収容凹部を形成するように構成し、
押圧面と絶縁端面によって設定される収容凹部の深さは、収容凹部に収容された部品が押圧面に密着した状態において絶縁端面から突出するように設定され、
収容凹部の深さを所定値に設定するために、押圧面に対する絶縁筒の進出距離を所定長さに設定するストッパ手段が設けられているとともに、絶縁筒に進出力を付与する付勢部材が設けられており、
溶接態様は、収容凹部に収容された部品を相手方の鋼板部品に溶接する部品溶接態様と、複数の鋼板部品を重合させて絶縁端面と押圧面が鋼板部品の表面を加圧した状態で鋼板部品を溶接するスポット溶接態様とされていることを特徴とする電気抵抗溶接用電極である。
