[0035] When in use, the wing plate is placed on the bottom plate 101, and the corrugated web is placed on the wing plate. The wing plate and the web can be pushed to move by an external pushing device, so that the two conveying tubes 102 can weld the connection between the wing plate and the web. Since the web is corrugated, the conveying tube 102 can always face the connection through the facing component, thereby improving the welding quality. During the welding process, flux is added into the conveying channel 103 through the flux box 107 and the connecting tube 106, and the flux is discharged from the bottom end of the conveying tube 102 to the connection. The wire feeding tube 104 is pushed to the connection through the external pushing component to achieve welding.
