If the size of the cross-flow fan blade to be welded changes greatly, the position of the fixed plate three 2 is adjusted. If the size of the cross-flow fan blade to be welded changes slightly, the telescopic rod 203 is elongated.

According to the welding position, the position of the welding head 107 is adjusted by rotating the lead screw 104 driven by the motor one 103. The welding head 107 can move in the three-dimensional space to adapt to different welding positions. When welding, the fan 305 is turned on. The welding smoke generated by welding enters from the air inlet 108, enters the air inlet pipe two 306 through the air inlet pipe one 109, is discharged from the air outlet connected with the fan 305 through the filter plate 301, and is discharged from the air outlet connected with the fan 305 through the filter plate 301.
