A first problem with conventional stud welding is that an operator holds a stud gun with a stud mounted thereon by hand and places the stud mounted on the stud gun at a predetermined position of a construction site. Even if it is set, it is not easy to perform accurate positioning. In addition, if the positioning is to be performed accurately, the work efficiency becomes very poor because the apparatus is heavy.

The second problem is that of the prior art, Japanese Patent Publication No. 4-45.

Claims (5)

[Claims] 1. A horizontal stud moving welding apparatus having a horizontal stud welding machine mounted on an upper surface of a pedestal, an actuator for vertically moving a pedestal laid on an upper end of the trolley so as to be able to move up and down, and a stud for clamping a stud of an irregular shape. A clamp mechanism, a frame for fixing the stud gun and the linear motion mechanism, a stud inclination adjusting bolt for fixing the frame to the upper surface of the pedestal and adjusting the horizontal, a steel driving member and a stud on the axis of the stud. A stud gun that generates an arc with respect to a contact position with the linear motion mechanism that reciprocates between a retracted state and a pressed state after fusion when the arc is generated; and a stud shaft on the front surface of the front end of the Fourem. A stud positioning guide pin fixed in parallel along the line, and a ferrule set on the front surface of the front end portion of the frame to be set. A horizontal stud moving welding device comprising a ferrule holding plate. 2. A frame for fixing the stud gun and the linear motion mechanism, wherein the X-direction moving mechanism moves the frame in the front-rear direction with respect to the stud axis, and the frame moves left and right with respect to the stud axis. The horizontal stud moving welding apparatus according to claim 1, further comprising a Y-direction moving mechanism that moves in a direction between the frame and the pedestal. 3. The frame according to claim 1, further comprising a level for detecting a horizontal state at a predetermined position on an upper surface of the frame, the frame fixing the stud gun and the linear motion mechanism.
