The invention provides a novel laser welding jig for a trial-manufacture vehicle. The novel laser welding tire film clamp comprises an upper cover plate, tire mold framework X-direction positioning plates, a spring pressing mechanism and partition plates; the number of the tire mold framework X-direction positioning plates is provided are two, and are made of rectangular plates correspondingly, one ends of the tire mold framework X-direction positioning plates are of polygonal structures, extending blocks are arranged at the top angles of the lower ends of the tire mold framework X-direction positioning plates, and a plurality of equal-spacing notches are formed in the upper side walls of the tire mold framework X-direction positioning plates; and the plurality of partition plates are arranged, one ends of the partition plates are clamped in the notches of the two tire mold framework X-direction positioning plates in a buckling mode to form a tire mold framework, the tire mold framework is in a plurality of connected Chinese character "jing" structures, and the upper cover plate is fixedly arranged on the tire mold framework; the spring pressing mechanism is fixedly arranged at oneends of the partition plates; and the invention further provides a use method of the novel laser welding jig for the trial-manufacture vehicle. According to the jig, the manual adjustment amount of the jig is reduced to the maximum degree, so that the trial manufacture efficiency of sample cars is improved, and the sample car trial manufacture is made to reflect actual production to a higher degree.
