Simulated welding frame

The utility model discloses a simulation welding frame which comprises a support (2), a welding pipe (4) and a pipe set (3). The pipe set is arranged on the support in a rotatable mode. The pipe set comprises a plurality of pipe fittings which are connected together. At least one pipe fitting comprises a cut-off end (3a). Welding operation is carried out between the welding pipe and the cut-off end (3a), or the welding pipe used for welding operation is arranged on the cut-off end in a detachable mode. The pipe set is arranged on the support in the rotatable mode so that the cut-off end on the pipe set can rotate to a plurality of positions along with the pipe set, and accordingly, different welding positions in a high-temperature superheater or a high-temperature reheater or an economizer can be simulated. Therefore, according to different welding levels of welding workers, welding positions with different difficulty degrees are selected for carrying out welding operation, the welding skills of different welding workers can be improved in a targeted mode, and the welding defects which may occur when the welding workers directly carry out welding on relevant equipment are reduced.
