1. Frame welding shall be positioned on the ground according to the frame size. Cut both ends of the frame material into 45 pieces. Spot welding after butt welding. After correction, the diagonal of the box should be equal.

2.中間長(zhǎng)豎管焊接每扇門3根長(zhǎng)豎管，均勻分布在邊框內(nèi)，定位間距為339毫米。擺放好位置后，先點(diǎn)焊，再校平，檢查無誤后再焊牢。

2. The middle long vertical pipe is welded with 3 long vertical pipes for each door, evenly distributed in the frame, and the positioning spacing is 339mm. After placing the position, spot welding first, then leveling, and then welding firmly after checking.

3.矛頭用橫管焊接每扇門4根，夾在中問長(zhǎng)豎竹之間、擺放好位置后，先點(diǎn)焊，再校平，檢查無誤后再焊牢:

3. The spearhead is welded with 4 pieces of horizontal pipe for each door, which is clamped between the middle and long vertical bamboo. After the position is placed, spot welding is carried out first, and then leveling is carried out. After checking, the welding is firm

4.中間短豎管焊接侮扇門4根.按圖樣中的位置擺好。先點(diǎn)焊，再校平，檢查無誤后再焊牢。

4. The middle short vertical pipe shall be welded with 4 doors, which shall be arranged according to the position in the drawing. Spot welding first, then leveling, and then welding firmly after checking.

5.短橫管焊接每扇門24根.按圖樣中的位置擺好。先點(diǎn)焊，再校平，檢查無誤后再焊牢。為防l上焊接變形，可問隔焊。由于順序打亂，焊點(diǎn)較多，焊完后應(yīng)檢查有無漏焊部位。

5. Weld 24 short horizontal pipes for each door, and place them according to the position in the drawing. Spot welding first, then leveling, and then welding firmly after checking. In order to prevent the welding deformation on L, the welding can be separated. Due to the disordered sequence and many solder joints, it is necessary to check whether there are missing parts after welding.

6.槍頭焊接依次將各槍頭分別焊在相應(yīng)的位置上.要求與橫桿垂直，正面朝前，不能扭曲。

6. Welding of gun head: weld each gun head in the corresponding position in turn. It is required to be vertical to the cross bar, face forward and not twisted.

7.花形焊接把所有花形分別擺放在相應(yīng)位置上，看是否合適，調(diào)整無誤后，先點(diǎn)焊到框架上，整體再檢查一遍，然后焊牢。

7. Pattern welding put all the patterns on the corresponding positions to see if they are suitable. After the adjustment is correct, spot weld the frame first, check the whole again, and then weld firmly.
