The invention relates to glasses, in particular to welding-free glasses and a processing technology thereof. The welding-free glasses comprise two glasses frames, glasses legs and nose pad assemblies,wherein the glasses legs are arranged at the two ends of the glasses frames; the nose pad assemblies are arranged on the two glasses frames; the glasses frames comprise an upper glasses frame and a lower glasses frame; openings are formed in the ends, which face the glasses legs, of the upper glasses frame and the lower glasses frame; pile heads are separately arranged at the ends, with the openings, of the upper glasses frame and the lower glasses frame; the pile heads comprise an upper pile head arranged on the upper glasses frame and a lower pile head arranged on the lower glasses frame; the upper pile head and the lower pile head are arranged side by side and can be attached to each other; the upper pile head and the lower pile head are separately provided with hooks; the two hooks are attached to each other; a spring plate is arranged on each hook in a sleeving manner; the glasses legs are connected with the hooks through clamping pieces; and the clamping pieces are abutted to the spring plates. By the welding-free glasses and the processing technology thereof, the labor cost can be saved, and the whole pair of glasses does not need a welding process.
