Iron gate has a long history, because many families use iron products at present, and the development trend of its raw materials and processing technology also has a development trend of more than 2000 years. Do you know the details of its processing technology? Then I'll introduce some common sense about its process.

铁艺大门焊接工艺：

Welding process of iron gate:

1.大门外框焊接。按照外框规格，在工作台上精细定位。把外框两边的宽度剪成45。焊接后焊接。标定精细(车架直线)，焊接牢固。焊接中长直管段。每个门均匀分布在外框架内，准确定位间隔时间不应超过5毫米。安装后先焊后拉直，检验精度后焊接牢固。

1. Gate frame welding. Fine positioning on the workbench according to the specification of the outer frame. Cut the width on both sides of the outer frame to 45. Weld after welding. Fine calibration (straight frame) and firm welding. Weld medium and long straight pipe sections. Each door shall be evenly distributed in the outer frame, and the accurate positioning interval shall not exceed 5mm. Weld before straightening after installation, and weld firmly after checking the accuracy.

2.大门各用横钢焊接四根保险丝，将其夹在竖竹中间，焊接后拉直，在中间用短竖钢焊接。每个门都有四个门。将零件按照样品图放置。焊接前先焊接，后拉直，检验焊接精度。

2. The gate shall be welded with four fuses with horizontal steel, clamped in the middle of the vertical bamboo, straightened after welding, and welded with short vertical steel in the middle. Each door has four doors. Place the parts according to the sample drawing. Before welding, weld first and then straighten to check the welding accuracy.

3.每个门都焊接24个短横向钢，按样品图中的零件放置。焊接前先焊接，后拉直，检验焊接精度。为避免焊接变形，应采用隔离焊接。由于顺序混乱，因此焊接点较多。焊后，检查是否有假焊位置。

3. Each door is welded with 24 short transverse steel and placed according to the parts in the sample drawing. Before welding, weld first and then straighten to check the welding accuracy. In order to avoid welding deformation, isolation welding shall be adopted. Due to the chaotic sequence, there are many welding points. After welding, check whether there is false welding position.

4.大门的锻造件和弯曲接头依次焊接在相关部件上。限制杆垂直于单杠，正对面，不可扭曲。花纹焊法是把所有图案放在相对位置上，看是否合适。调准后，焊接到车架上，对车架进行完全检查，焊接牢固。

4. The forged parts and bending joints of the gate are welded on relevant parts in turn. The limiting rod is perpendicular to the horizontal bar, directly opposite, and cannot be twisted. Pattern welding is to put all patterns in relative positions to see if they are appropriate. After alignment, it shall be welded to the frame, and the frame shall be completely inspected and firmly welded.

5.电弧焊过程：CO2气体保护焊接选择CO2。(焊点均匀、密封牢固)不锈钢焊条。

5. Arc welding process: CO2 is selected for CO2 gas shielded welding（ Stainless steel welding rod with uniform welding points and firm sealing.

6.大门金属表面处理：室外生产加工采用热浸镀锌工艺，涂层良好，耐腐蚀，颜色多样。

6. Metal surface treatment of gate: hot dip galvanizing process is adopted for outdoor production and processing, with good coating, corrosion resistance and various colors.
