を連結するための接続具として働くスリーブを意味する
。
説明の便宜上、以下では上記した特定のスリーブの場合
について言及するが、それらは本発明を説明するための
一例に過ぎない。
［従来の技術］ ２つのプラスチック製チューブを結合する場合、同材料

即ち、スリーブがユニオン継手として働き、スリーブの

［発明が解決しようとする問題点］ しかしながら、この簡単な方法は、制御上難点がある。
というのは、チューブとユニオン継手との間の堅固なブ
ロックの形成は漸進的な現象なので、この現象は温度と
量という２つの物理的指針によって調べることはできて
も外部から見ることができないからである。
実際、電流溶接源が接続されると、コイルに電流が流れ
次のような一連の結果をもたらす。
コイルがスリーブに埋め込まれているため電流によって
生じた熱が周辺域における材料の加熱を引き起こして次
第に融解して行き表面へと熱膨張が達し、チューブ外部
に圧力が加わり、この圧力が増加する。
次いで、チューブ材が融解してチューブに対しスリーブ
が押圧した状態での溶接となる。
この時点で電流が切られなければ、融解材料の熱膨張に
より溶接域での圧力増加が生じる。
何故なら、コイル各側の側方域が冷たいままであるから
であり、従って材料ロスが防がれ溶接圧が確立する。
従って、材料の湿度又は量をチェックできれば、これら
指針のいずれかが所定値に達した時点で電流の遮断を行
