Abstract
(EN) According to the present invention, an energy amount adjustment is performed with respect to one or more specific application units (241, 242) when applying energy to a cylindrical member pair (40), in which another cylindrical member (11) is completely inserted into a cylindrical member (22), and melting and welding the cylindrical member pair in the circumferential direction. This adjustment is performed according to a rotation angle of the cylindrical member pair so that the relationship Pd+Pw>θ is satisfied between an output down rotation angle Pd by which the energy amount is reduced from a normal energy amount HP during a welding completion process, an overlap rotation angle Pw by which a portion irradiated with the energy and surrounding the vicinity of the cylindrical member pair overlaps with the normal energy amount HP, and a separation angle θ between adjacent application units in the rotation direction around the axis.
(FR) Selon la présente invention, un réglage de quantité d'énergie est effectué par rapport à une ou plusieurs unités d'application spécifiques (241, 242) lors de l'application d'énergie à une paire d'éléments cylindriques (40), dans laquelle un autre élément cylindrique (11) est entièrement inséré dans un élément cylindrique (22), et la fusion et le soudage de la paire d'éléments cylindriques dans la direction circonférentielle. Ce réglage est effectué en fonction d'un angle de rotation de la paire d'éléments cylindriques de sorte que la relation Pd+Pw>θ est satisfaite entre un angle de rotation de sortie vers le bas Pd, par lequel la quantité d'énergie est réduite par rapport à une quantité d'énergie normale HP pendant un processus d'achèvement de soudage, un angle de rotation de chevauchement Pw, par lequel une portion irradiée avec l'énergie et entourant le voisinage de la paire d'éléments cylindriques chevauche la quantité d'énergie normale HP, et un angle de séparation θ entre des unités d'application voisines dans la direction de rotation autour de l'axe.
(JA) 円筒部材(22)の内側に他の円筒部材(11)が挿入済みの円筒部材ペア(40)にエネルギーを印加して円筒部材ペアを周方向に溶融して溶接するに当たり、少なくとも一つの特定印加部(241,242)についてのエネルギー量の調整を実行する。この調整は、溶接終了過程においてエネルギー量を定常エネルギー量HPから低減させる出力ダウン回転角度Pdと、円筒部材ペアの周囲に亘るエネルギーの照射部位が定常エネルギー量HPでオーバーラップするオーバーラップ回転角度Pwと、軸心回りの回転方向において隣り合う印加部の隔たり角度θと、の間に、Pd+Pw>θの関係が成立するように、円筒部材ペアの回転角度に対応付けて実行される。
