Claims

[Scope of Claim for Utility Model Registration] 1. In an automatic welding device having a tracing mechanism that performs horizontal fillet welding on both sides, a first welding torch arranged opposite to the first welding torch and an assembled member to be welded connected to the first welding torch in advance in the direction of welding progress. a two-axis detector that comes into contact with the vertical member and the horizontal member to continuously detect the welding line; a second welding torch and the second welding torch that is connected to the second welding torch in advance in the direction of welding progress; a single-axis detector capable of continuously detecting the position of a vertical member of an assembly member to be welded, which is provided ahead of the welding member in the welding progress direction, and detecting the end of the vertical member; and the two-axis detector. a main slide mechanism profiling control device that controls the vertical and horizontal positions of the first welding torch and the vertical position of the second welding torch based on position detection signals from the main slide mechanism; An automatic welding apparatus having a tracing mechanism, characterized in that the automatic welding apparatus is equipped with a tracing control device for a slave slide mechanism that controls the lateral position of the second welding torch that is activated by a position detection signal from the single-axis detector. 2. A first slide mechanism that slides in a horizontal direction perpendicular to the traveling direction is installed on the traveling trolley, and
A second slide mechanism that slides in the vertical direction is installed on the slide mechanism, and a pedestal that extends in the same direction as the sliding direction of the first slide mechanism is attached to the top of the second slide mechanism. A first welding torch is attached to one side of the pedestal via a support, and a third slide mechanism that slides in the same direction as the first slide mechanism is installed on the other side of the pedestal. A second welding torch is attached to the third slide mechanism via a strut, and the second welding torch is placed adjacent to and facing the first welding torch, and is placed ahead of the second welding torch in the welding progress direction. A detector is attached, and the operation of the first slide mechanism and the second slide mechanism is controlled based on the position detection signal of the assembly member to be welded by the two-axis detector, and the first welding torch and the second welding are performed. The torch is configured to follow the welding line, and a single-axis detector is installed close to the second welding torch and ahead of the two-axis detector in the welding progress direction, so that no damage is caused by the single-axis detector. Based on the position detection signal of the welding assembly member, the operation of the third slide mechanism is controlled to correct the horizontal tracing of the second welding torch, and the same uniaxial detector detects the end of the vertical member of the welding assembly member. An automatic welding device having a tracing mechanism, characterized in that the automatic welding device is configured to perform welding up to the end portion based on a detection signal.
