Middle section of left side outer panel左侧围外板中段

Removal procedure拆卸程序

1. Remove the middle section of the left side outer panel1. 拆卸左侧围外板中段 1 Remove the sealant around the middle section of the left side outer panel.除去左侧围外板中段周围密封胶。

2 Clean the welding area to expose the solder joints, use an electric drill to remove the solder joints in the raised area ①, use a chisel and hammer to disassemble the welding joints, cut areas A, B, C, D, and E, and remove the middle section of the left outer panel.清洁焊接区域，露出焊点，使用电钻钻除凸起区域①的焊点，使用凿子和锤子拆开焊接点，切割A、B、C、D、E区域，取下左侧围外板中段。   Caution:注意： ♦  Cut carefully to avoid damaging the internal stiffeners.小心切割，避免损伤内部加强板。

Installation procedure安装程序

Caution:注意： ♦  The center of the solder joint should be placed at the center of the overlapping surface.焊点中心应布置在搭接面的中心处。 ♦  In order to ensure that the strength of the car body remains consistent with the original car, it is recommended to add a certain number of welding spots or plug welding.为保证车身强度与原车保持一致，建议增加一定数量的焊点或塞焊。 ♦  When the accessibility of the spot welding gun is insufficient, the plug welding process is used instead.点焊枪可达性不足时，使用塞焊工艺替代。 ♦  When using MAG welding for plug welding or full welding, structural adhesive cannot be applied to the area above 30mm.使用MAG焊进行塞焊或全焊时，30mm以上区域范围不能涂抹结构胶。

1. Install the middle section of the left side outer panel1. 安装左侧围外板中段

1 Cut the left side outer panel on the workbench, leaving a wide enough cross section to add the new parts.在工作台上切割左侧围外板，留有足够宽的横截面加装新零件。 2 Sand the weld surfaces and bonding surfaces of the new parts until metal is exposed, then use a silicone-free cleaner to clean the body and bonding areas of the new parts.打磨新部件的焊缝表面和粘合表面，直至有金属暴露出来，然后用无硅油清洁剂，来清洗车身和新部件的粘合区域。

3 Apply structural glue to the welding position ①.在焊接位置①上涂抹涂抹结构胶。 4 Check whether the cut piece in the middle section of the left side outer panel overlaps with the front and rear hems of the side outer panel.检查左侧围外板中段切割件是否与侧围外板前、后段卷边重叠。 Overlap width: 50±5mm重叠宽度：50±5mm   Caution:注意： ♦  Cut the middle edge of the left side outer panel and remove the excess to form an ideal welding gap.切割左侧围外板中段棱边，清除多余部分，形成理想焊接缝隙。

5 Use self-locking clips to fix the middle section of the new left side outer panel to the body, use a spot welder to weld the area ① as shown in the figure, and use a MAG welder to weld the area ② as shown in the figure.使用自锁卡夹将新左侧围外板中段固定到车身上，使用点焊机焊接图示区域①，用MAG焊机焊接图示区域②。 6 Use sealant to seal the joints between the component and the body.使用密封胶密封部件与车身之间的接缝。 7 Spray the exterior surface with topcoat.对外观面进行面漆喷涂。
