Laser welding is increasingly employed as an effective method to join small areas of parts with small distortions. Distortions of micrometer or sub-micrometer level generated after joining automobile parts are treated over laser welding, which is a process with small distortions. In this study, a general-purpose method, which decreases distortions without special processes before/after welding, is discussed. Consideration based on fundamental experiments and theoretical analyses is presented in order to understand a deformation behavior during a welding process, and to employ a technology into actual production lines. This paper deals with experimental methods and theoretical analyses about bending deformations in joining cylindrical parts by circumferential welding. Transition of bending deformations is discussed in order to control a residual deformation. A new method to control a distortion from results of the distortion behavior analysis is proposed to be employed into a production line.
