As shown in Figs. 1 to 3, in general, the TWB process changes the welding situation every time the vehicle is changed because of frequent parts change work, which is one of the main factors that greatly decrease the productivity, that is, working with various models. Only then will TWB be produced for the vehicle. Particularly, in the case of part change work, the product that dimples must dimple the cylinder by setting the dimple coordinates according to the dimple position and setting the dimple cylinders (2) and (5) to the dimple position coordinates. Because dimple operation is possible only when assembled to the claw bases (3) and (9), it takes a lot of time when changing parts and decreases the delivery time hit ratio, which is the biggest issue in the production of automotive parts due to the decrease in productivity of TWB process and delay of delivery. Was the main cause.

Moreover, the dimple change setting operation during the part change operation of the automatic laser welding machine is difficult and accurate to assemble and set the upper and lower dimple cylinder caps (2) and the lower cylinder (5) to the dimple coordinate bases (3) and (9). Due to the dimple setting work in one place, the TWB products are frequently defective due to the mistake of assembling the dimpler cylinder and the caps (2, 5), resulting in repeated delays in delivery and the dimple change in a narrow place. There is a risk of manpower loss and safety accidents due to the heavy load of workers and the difficulty of part change work caused by the setting work by the worker (1). The main cause of such problems is a decline in profits.
