[0008] As a preferred embodiment of this utility model, the lower part of the drive cylinder and the top part of the top connecting plate are fixedly installed with several bolts, and the lower output end of the drive cylinder and the upper part of the piston column are keyed together.

[0009] The bottom of the piston column and the middle position of the top of the fixed disc are integrally connected, and the welding guns are fixedly installed below the surrounding edge of the fixed disc.

[0010] The top of the welding guns is also fixedly connected with hydraulic rods, the top of the hydraulic rods is fixedly installed on the bottom surrounding edge of the fixed disc, and the welding guns can move up and down under the action of the hydraulic rods.

[0011] The internal cavity of the placing groove can be used for placing the periphery welding end of the head flange, and the welding end is placed below the internal welding groove.

[0012] A handle in U-shaped structure is fixedly installed outside the four supporting frames, and self-locking universal wheels are fixedly installed at the bottom of the supporting frames.

[0013] Compared with the prior art, the welding efficiency of the head flange as a whole can be improved.

[0014] In the utility model, when the welding tool is used, the surrounding edge of the head cylinder and the welding position of the flange to be welded are placed in the placing groove, then the fixed disc and the welding guns below are driven to move downwards by the driving cylinder, and then the welding end can be simultaneously welded by the welding guns, so that the welding efficiency of the head flange as a whole can be improved.
