Abstract: The method comprises introducing (S1) components into a welding cell, generating (S2) first weld seams for connecting the components, detecting a first weld parameter of the first weld seam, evaluating the detected weld parameter whether it meets a predetermined weld criterion, generating (S6) second weld seams for connecting the components beside the first weld seam if the first weld seam parameter does not fulfill the first weld seam criterion, and discharging (S4) the welded components from the welding cell. The components are clamped in a welding device. The method comprises introducing (S1) components into a welding cell, generating (S2) first weld seams for connecting the components, detecting a first weld parameter of the first weld seam, evaluating the detected weld parameter whether it meets a predetermined weld criterion, generating (S6) second weld seams for connecting the components beside the first weld seam if the first weld seam parameter does not fulfill the first weld seam criterion, and discharging (S4) the welded components from the welding cell. The components are clamped in a welding device, and are removed from the welding device only after generating the first and second weld seams. A second weld seam parameter is detected and evaluated if the second weld seam meets the predetermined weld criterion. If the first weld seam: does not fulfill the predetermined weld criterion, a weldability parameter of the first weld seam is compared with a predetermined weldability criterion; and fulfills the weldability parameter according to the predetermined weldability criterion, the second weld seam is produced beside the first weld seam. If the components fulfill the weldability parameter according to the predetermined weldability criterion, the components are discharged from the welding cell without the second weld seam. If the weld parameters of the first weld seam do not fulfill the predetermined weld criterion and the weldability parameters of the first weld seam do not fulfill the predetermined weld criterion, the components are discharged from the welding cell and stored in a first storage area. If the weld parameters of the first and second weld seams do not fulfill the predetermined weld criterion, the components are discharged from the welding cell and stored in the first storage area. If the weld parameter of the first and second weld seams: do not fulfill the predetermined weld criterion, the components are discharged from the welding cell and stored in a second storage area; and fulfill the predetermined weld criterion, the components are discharged from the welding cell and stored in the second storage area. The first weld seams are generated at different positions of the components, where the evaluation of each welding parameter is carried out after the creation of a respective weld seam. The second weld seams are generated after the generation of the first weld seams. The first and/or second weld seam is generated by a laser remote welding, and the welding parameters of the first and/or second weld seam describe the stability of the steam passage. Independent claims are included for: (1) an apparatus for producing a weld seam for connecting components in a motor car region; and (2) an assembly comprising components.
