Title: Method of jointing steel strips
Inventor: TAKEMOTO MASAKANE
IPC: B23K26/21
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To improve productivity and joint quality by passing between a welding roll and multiple holding rolls arranged to be inclined, applying width- direction force so that pressing force works on the edge end face, and performing laser welding. SOLUTION: Two types of steel strips 1 and 2 different in material and thickness are passed in parallel between upper holding rolls 3 and 4 and a lower welding roll 5. The holding rolls 3 and 4 are inclined by the angles θ1 and θ2, respectively, against the longitudinal direction of the welding roll 5. The holding roll 3 provided above the welding roll 5 moves the steel strip 1 to the welding position while passing it against an entry-side edge guide 7 and an exit-side edge guide 8. The holding rolls 4 move the steel strip 2 while constraining it so that the joint face 10 is pressed against the joint face 10 of the steel strip 1, thus applying surface pressure between the edges of the steel strips 1 and 2 to eliminate a clearance. Subsequently the steel strips 1 and 2 are welding by irradiating laser beams to the joint faces 10.
