The following is to introduce the welding process of iron gate:

　　1.边框焊接  按边框尺寸在地上定位。将边框料的两端宽边上切成45。对接后点焊。校正无误<方框的对角线要相等)后焊牢。

　　1. The frame shall be positioned on the ground according to the frame size. Cut the two ends of the border material into 45. Spot welding after butt welding. After the correction is correct, the diagonal lines 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, which are evenly distributed in the frame, and the positioning distance is 339 mm. After the position is placed, spot welding shall be carried out first, and then leveling shall be carried out, and then the welding shall be firm after the inspection.

　　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 horizontal pipe for each door, which is sandwiched between the long vertical bamboo in the middle. After the spearhead is placed in a good position, spot welding and leveling shall be carried out first, and then the spearhead shall be welded firmly after inspection

　　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. Four short vertical pipes in the middle shall be welded and arranged according to the position in the drawing. First spot welding, then leveling, and then welding firmly after checking.
                                                  

　　5.更短横管焊接每扇门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 pieces of each door with the shortest horizontal pipe, and arrange them according to the position in the drawing. First spot welding, then leveling, and then welding firmly after checking. In order to prevent welding deformation on the upper part, separate welding can be conducted. Due to the disorder of the sequence, there are many welding spots. After welding, check whether there is missing welding position.

　　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. The gun head shall be welded on the corresponding position in turn. It is required to be vertical to the cross bar, with the front face facing forward, and shall not be 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. Flower shape welding: place all flower shapes in corresponding positions to see if they are suitable. After adjustment, spot weld them to the frame first, check the whole again, and then weld them firmly.

　　以上介绍的是铁艺大门的焊接工艺，希望大家有所了解。

　　The above is the welding process of iron gate, I hope you have some understanding.
