PURPOSE: A welding turn-table is provided to reduce welding failure since a first gear engages with the second gear of the bottom edge of a turn-table and in this state, the turn-table rotates and as a result, a workpiece is semi-automatically welded. CONSTITUTION: A welding turn-table comprises a lower body(20) and an upper body. The lower body comprises a penetrating shaft(21) and a turn-table(22). The penetrating shaft penetrates the central bottom of the turn-table. The upper body comprises a first fixing block(31), first and second LM(Linear Motion) guides(32,36), a ball screw(33), first and second transfer plates(34,37), a fixing plate(35), an extended plate(38) and a spring(39). The first LM guide is fixed by a plurality of bolts to the top of the first fixing block in two rows. Both ends of the ball screw are supported on a second bearing member(331) and the ball screw is rotated.
