SUBMERGED ARC WELDING DEVICE FOR BUTTING PIPE

摘要

The present invention relates to a submerged arc welding device for butting a pipe which forms an even welding bead and improves a welding accuracy. The submerged arc welding device comprises: a main frame, a fixing frame, and a submerged arc welding unit. The submerged arc welding unit comprises: a vertical welding frame installed in one side of the main frame to be able to move upwards and downwards; a horizontal welding frame installed to move from side to side from the vertical welding frame; a wire supplier consistently supplying wire from a wire reel on which the wire is wound; a flux supplier supplying flux accommodated therein through a flux tube; a welding torch fixated to a horizontal welding frame and receiving the wire from the wire supplier, wherein the welding torch arc-welding a temporary welding unit by generating an arc in accordance with an application of power; a flux sprayer fixated to a front of the welding torch and receiving the flux by being connected to the flux tube of the flux supplier, wherein the flux sprayer sprays flux to the temporary welding unit arc-welded by the welding torch; a Y-axis rotation unit fixated to a lower part of a vertical welding frame in order for the welding torch to move in a width direction of the temporary welding unit, rotating the horizontal welding frame around the Y-axis; and a horizontal movement control unit connecting the horizontal welding frame and the Y-axis, and fixating or releasing the horizontal movement of the welding frame.;COPYRIGHT KIPO 2016
