An automatic welding apparatus for a truss girder is provided to improve productivity by easily welding a horizontal rod and a vertical rod to both ends of the truss girder. An automatic welding apparatus for a truss girder(10) comprises: horizontal welding devices(100) which are installed at both sides such that the horizontal welding devices face each other, and which welds the horizontal rods to the truss girder after placing horizontal rods at both ends of a truss girder; vertical welding devices(200) which are installed at both sides next to the horizontal welding devices such that the vertical welding devices face each other, and which welds the vertical rods to the truss girder after placing vertical rods at ends of the truss girder to which the horizontal rods are welded; and transfer parts(400) which are installed at both ends such that the transfer parts are parallel to each other to sequentially supply the truss girders to the horizontal welding devices and the vertical welding devices by transferring the truss girders in a state that the truss girders are put down on both sides of the transfer parts.
