The first cross beam 801, the second cross beam 802 and the plurality of intermediate beams 803 are provided with notches 800. During assembly, the notches 800 of the intermediate beam 803 need to be inserted into the notches 800 of the first cross beam 801 and the second cross beam 802, and then welding is performed. The first cross beam 801, the second cross beam 802 and the plurality of intermediate beams 803 are metal composite materials.

However, it is obvious that the above-mentioned sheet metal welding device is not convenient for assembling and welding the aircraft wing spar.
