The present invention relates to an automatic transfer device of a welding torch for automatically realizing fillet welding.

Fillet welding is to weld a variety of section steel used in shipbuilding, construction, bridges, etc. to the steel sheet, a: uniformly welded to the butt portion of the form or T-shaped steel to reinforce the steel sheet.

Since the welded part is a cornered position, the workability is worse than that of general welding, and it has a condition that welding defects are likely to occur. In the past, the worker performed the welding manually, which greatly reduced the work efficiency and caused a poor welding condition. However, in recent years there is a trend to improve this by using an automatic welding machine.

However, this does not realize full automation of the welding operation. That is, the above automatic welding machine is equipped with a welding head composed of a device and its accessories necessary for welding on a traveling cart, and the welding is performed by moving the guide rail on a parallel to the welding line. There are inherent irrationalities.

First: Because the torch must fit the welding line exactly, the guide rail should be laid precisely to allow constant movement of the bogie.

However, this involves the trouble of measuring and adjusting the position where the guide rail is placed on the weld line every time.

Secondly, since the worker moves the truck while observing the welding state with the naked eye, the handling manpower is constantly required.

The present inventors have come to develop the present invention in order to solve the above-mentioned problems and provide several remarkable advantages.

The primary object of the present invention is a fully automated welding device which allows the operator to operate or handle only briefly at the start and end of the welding, so that all the welding can be carried out unattended.

Another object of the present invention is to be configured to weld both sides back to the section steel at the same time, to increase the work efficiency by only one one-way running and to achieve a uniform welding state.

Features of the present invention that can achieve the above object is to configure a bogie, a drive unit and a control unit having a pair of welding torch, by using a shape steel itself as a guide rail to achieve a constant welding run, more specific details are attached A description with reference to the drawings as follows.
