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.中间长竖管焊接每扇门3根长竖管，均匀分布在边框内，定位间距为339毫米。摆放好位置后，先点焊，再校平，检查无误后再焊牢。

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.矛头用横管焊接每扇门4根，夹在中问长竖竹之间、摆放好位置后，先点焊，再校平，检查无误后再焊牢:

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.中间短竖管焊接侮扇门4根.按图样中的位置摆好。先点焊，再校平，检查无误后再焊牢。

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.短横管焊接每扇门24根.按图样中的位置摆好。先点焊，再校平，检查无误后再焊牢。为防l上焊接变形，可问隔焊。由于顺序打乱，焊点较多，焊完后应检查有无漏焊部位。

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.枪头焊接依次将各枪头分别焊在相应的位置上.要求与横杆垂直，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别摆放在相应位置上，看是否合适，调整无误后，先点焊到框架上，整体再检查一遍，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.
