In order to make the inner clapboard of the box beam and the upper and lower flange plates welded more tightly, the gap required for vertical electroslag welding is reserved between the clapboard and the wing plate when the clapboard is assembled,
The bottomed box beam is passed through the roller table transported to the gantry type vertical electroslag welding frame, and the vertical electroslag welding machine hanging on the gantry frame will carry out vertical electroslag welding on the reserved hole of the workpiece, and the gantry frame can walk arbitrarily in the length direction of the workpiece.
As shown in the picture above, there is a partition in the middle of the box beam. Under normal circumstances, we can only weld to three sides. The last side is specially assembled, and then the cover plate is turned 90 degrees and electroslag welding is adopted.
Box beamflux electroslag welding machine is divided into gantry mobile electroslag welding machine and cantilever mobile electroslag welding machine. As a manufacturer of steel structure production line, we can provide suitable H-beam production line equipment according to customer needs

The box beam vertical electroslag welding machine can be divided into wire electroslag welding and melting nozzle electroslag welding in the welding process:
1.The welding process of the two is basically the same. Arc starting - adding flux - slag forming completed - contact between the melting nozzle and slag pool - normal welding - when electroslag welding is completed - adding arc suction block - stop welding .
2.The difference between wire electroslag welding and melting tip electroslag welding is that wire electroslag welding is a welding method in which the welding wire is sent to the welding part through a non-melting water-cooled electroslag welding torch.
During the welding process, the electroslag torch rises with the rising liquid level of the welding pool. At present, in the electroslag welding market of steel structure box beams, filament electroslag welding is used more.

Welding cost |
Taking a 500*500-900mm box beam as an example, the welding cost of the fuse electroslag welding machine is about 5% lower than that of the melting tip electroslag welding machine. |
