Description

[Detailed description of the invention]

The present invention relates to a reversing device for welding. More details () relates to a welding reversing device that can invert architectural and civil engineering steel materials to which joints, etc. are welded, and always keep them in a downward position and perform good welding. When welding lips, plates, or joints to long beams or pillars, weld the main materials such as beams or pillars on a table such as H-beam steel while inverting them using a crane or the like. Therefore, the work of reversing the main material is dangerous and difficult, and work efficiency and good welding cannot be achieved.The present invention was developed in view of the above-mentioned problems. Hereinafter, an embodiment of the present invention will be described in detail using direction III'. A pedestal 5 is swingably provided on top of the pedestal 5, and a plurality of pedestals 7 are arranged so as to be freely adjustable in their positions in directions approaching and away from the pedestal 5 and are facing each other and are 0-tiered.
