The invention discloses an electric welding optimization device for computer technology research. The electric welding optimization device comprises a fixed housing, and a connecting plate is welded on the outer wall of one side of the fixed housing; a lampholder is welded on the outer wall of one side of the connecting plate; an illuminating lamp is connected in the lampholder in a threaded manner; an opening I is formed in the outer wall of the top of the fixed housing; a connecting barrel is inserted in the opening I; a thermal resistor is connected in the connecting barrel through a conducting wire; a rotating shaft seat is welded on the outer wall of one end of the connecting barrel; a telescopic sleeve is rotatably connected to the inner wall of the bottom of the rotating shaft seat;a telescopic rod is connected in the telescopic sleeve in a sleeving manner; and baffle plates are welded on the outer walls of the two sides of the telescopic rod. According to the electric weldingoptimization device, working efficiency of workers is improved, welding speed is increased, operation is simple, welding cost is reduced, the situation that operation errors are caused as the workerscannot see electronic elements clearly can be avoided, working safety of operators is indirectly guaranteed, and resource waste is avoided.
