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

　　1.邊框焊接  按邊框尺寸在地上定位。將邊框料的兩端寬邊上切成45。對接后點焊。校正無誤<方框的對角線要相等)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.中間長豎管焊接  每扇門3根長豎管，均勻分布在邊框內，定位間距為339毫米。擺放好位置后，先點焊，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, 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.矛頭用橫管焊接每扇門4根，夾在中問長豎竹之間、擺放好位置后，先點焊，再校平，檢查無誤后再焊牢:

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

　　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.更短橫管焊接每扇門24根.按圖樣中的位置擺好。先點焊，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，焊點較多，焊完后應檢查有無漏焊部位。

　　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.槍頭焊接依次將各槍頭分別焊在相應的位置上.要求與橫桿垂直，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別擺放在相應位置上，看是否合適，調整無誤后，先點焊到框架上，整體再檢查一遍，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.

　　以上介紹的是鐵藝大門的焊接工藝，希望大家有所了解。

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