Title (EN) METHOD FOR MANUFACTURING CYLINDRICAL MEMBER
(FR) PROCÉDÉ DE FABRICATION D’ÉLÉMENT CYLINDRIQUE
(JA) 円筒状部材の製造方法
Abstract:
(EN) The method is characterized by including: a butting step for rolling a flat metal plate (1) into a cylindrical member to be welded (1A) and butting end faces thereof against each other, thereby forming a butt portion (J1); an auxiliary member arranging step for arranging a curved portion (K1), which is formed at a backing jig (K), on the inner circumferential surface side of the butt portion (J1) and also arranging an auxiliary member (10) on the outer circumferential surface side of the butt portion (J1); and a friction stir step for inserting a rotating stirring pin (F2) from the surface (10a) side of the auxiliary member (10) and relatively moving a rotary tool for welding (F) along the butt portion (J1), thereby friction stir welding the butt portion (J1), with only the stirring pin (F2) being in contact with the cylindrical member to be welded (1A) and the auxiliary member (10).
(FR) La présente invention concerne un procédé qui est caractérisé en ce qu’il comprend : une étape d’aboutement pour laminer une plaque métallique plate (1) en élément cylindrique à souder (1A) et abouter des faces d’extrémité de celui-ci l’une contre l’autre, de façon à former ainsi une partie d’aboutement (J1) ; une étape d’agencement d’élément auxiliaire pour agencer une partie incurvée (K1), qui est formée au niveau d’un gabarit de support (K), sur le côté de surface circonférentielle interne de la partie d’aboutement (J1) et également agencer un élément auxiliaire (10) sur le côté de la surface circonférentielle externe de la partie d’aboutement (J1) ; et une étape d’agitation par friction pour insérer une tige d’agitation rotative (F2) depuis le côté de surface (10a) de l’élément auxiliaire (10) et déplacer relativement un outil rotatif pour soudage (F) le long de la partie d’aboutement (J1), de façon à souder par agitation par friction la partie d’aboutement (J1), seule la tige d’agitation (F2) étant en contact avec l’élément cylindrique à souder (1A) et l’élément auxiliaire (10).
(JA) 平板状の金属板(1)を丸めて円筒状被接合部材(1A)を形成するとともに、端面同士を突き合わせて突合せ部(J1)を形成する突合せ工程と、裏当て治具(K)に形成された曲面部(K1)を、突合せ部(J1)の内周面側に配置するとともに、突合せ部(J1)の外周面側に補助部材(10)を配置する補助部材配置工程と、回転する攪拌ピン(F2)を補助部材(10)の表面(10a)側から挿入し、攪拌ピン(F2)のみを円筒状被接合部材(1A)及び補助部材(10)に接触させた状態で、突合せ部(J1)に沿って接合用回転ツール(F)を相対移動させて突合せ部(J1)を摩擦攪拌接合する摩擦攪拌工程と、を含むことを特徴とする。
