    Abstract: PROBLEM TO BE SOLVED: To form a groove with high precision on the inside surface of a cylindrical workpiece by irradiating the surface with a laser beam nearly orthogonally to it. SOLUTION: A laser generator 14 for emitting a laser beam 12 is arranged inside a casing 11, and a cylindrical head 16 is installed coaxially with the laser generator 14. The laser beam 12 emitted from the generator 14 is converged by a condensing lens 18 provided in the head 16, and is thereafter refracted in a direction nearly orthogonal to the axial line 29 of the head 16 by a reflection mirror 24 arranged inside the head 16. This refracted laser beam 12 is emitted nearly orthogonally to the inner circumferential face 22 of the workpiece 20, and a groove 40a (40b) is formed under a thermal action of the laser beam 12.

    Abstract: PURPOSE:To obtain the surface of a brazed joint with less thermal strain and to enable automation, by coating a heat absorbing and dissipating material on the outside plate panel at the circumferential edge of a brazed part and providing a press roll to a torch holder. CONSTITUTION:A heat absorbing and dissipating material P is beforehand coated on the front and rear surfaces of the outside plate panel at the circumferential edge in a brazed part prior to brazing. A bracket 14 is acted by the respective compression coil springs S provided on parallel bars 13 so as to press the body Ha of a torch holder H toward the outside on the opposite side of a mounting plate 11 so that press rolls R press both side edges of a joggle type joint part J to prevent said edges from floating. Bead brazing is progressed while preventing the floating of the panel by the heat input of brazing by pressing both side edges of the brazed part of the joint from both sides with the brazing rod 5 of a torch T as a center.

    Abstract: 【課題】シリンダ壁と外壁の間を強固に繋ぐことのできるセミクローズドデッキ型のシリンダブロックの製造方法を提供する。 【解決手段】ウォータージャケット12の開口部14にブリッジ材20を設置すると共に、このブリッジ材20の上面20aの中央部に、シリンダ軸と平行な軸を回転中心として回転するFSWツール30のプローブ32を押し当てる(ステップ1)。ブリッジ材20の側面がシリンダ壁16と外壁18の両方に当接するまでの所定時間に亘って、上面20aの中央部にプローブ32を押し当てる状態を保持する(ステップ2)。プローブ32を上面20aに押し当てながら、上面20aの中央部から外壁18に至るまでFSWツール30の位置を移動して外壁18とブリッジ材20を摩擦撹拌接合し、その後、トップデッキ10aからプローブ32を引き離す(ステップ3)。 【選択図】図1
