Abstract: A clamping apparatus for clamping shaped parts which are welded along a welding contour by irradiation with a laser beam, includes a first clamping plate used as a holder for a first shaped part, a second clamping plate which is designed to apply a clamping force to the first shaped part and a second shaped part arranged thereon, an outer clamping jaw including a recess and an inner clamping jaw arranged in the recess, which together form the second clamping plate, a passage gap for the laser beam formed in sections between the outer clamping jaw and the inner clamping jaw, and one or more fastening elements which connect the outer clamping jaw with the inner clamping jaw in sections and which bridge the passage gap; and further includes a mirror element arranged such that the laser beam is reflected onto a section of the welding contour.
