HORIZONTAL BUTT JOINT HIGH DEPOSITION WELDING APPARATUS AND METHOD THEREFOR

摘要

The present invention provides an apparatus and a method for high deposition welding a horizontal butt joint which can form a high deposition welded part while forming a root part when high deposition welding is carried out relative to a bevel in case of automatic welding of a horizontal butt joint, thereby achieving high deposition welding without any defect of the inside and surface of a welded cross section and reducing the number of welding passes. The horizontal butt joint high deposition welding apparatus is installed on a traveling device part in a welding direction by a welding tip so as to move in a forward direction of welding progress and a horizontal butt joint high deposition welding method, thereby preventing the molten metal from running down, allowing a user to easily handle the apparatus, reducing weight, and completing surface beads because a lower part is filled with molten metal.

主权项

1. A horizontal butt joint high deposition welding apparatus comprising:
a traveling device part for periodically repeating weaving and conveying of a welding tip in a specific direction relative to an upper parent metal and a lower parent metal; a welding torch which has a welding tip and is mounted on the traveling device part; a copper shoe device which is mounted on the traveling device part to be located in a welding direction by the welding tip; and a control unit for controlling welding conditions according to weaving positions of the welding torch in consideration of a bevel form of a horizontal welding joint, wherein the control unit conveys the traveling device part to perform weaving traveling along a plurality of nodal points and controls one of welding current, welding voltage, wire supply speed, traveling speed in a movement section between the nodal points, stopping time at the nodal points, weaving speed and weaving width to carry out high deposition welding relative to the bevels.
