12.12.2.1 Precautions of Safety

When maintenance is performed for body and sheet metal, the following precautions of safety shall be strictly
observed:

1. When the body and sheet metal is welded, cut or polished, please wear protective clothing, protective

goggles, gloves and working shoes.

2. The welded area shall be in an environment with good ventilation.

3. Before welding, please disconnect the battery and cover terminal.

4. If sparks may be produced when operation is performed near the battery, please dismantle the battery.

5. Before components of the complete vehicle are dismantled, please fix the vehicle on vehicle suspension to

avoid the center of gravity of complete vehicle changes to influence operational safety.

6. Connect the grounding wire of welding equipment directly on parts for welding. Please make sure no electric

conduction parts exist between grounding point and point of welding when operating.

7. Grounding wire and electric welding electrode shall not contact with electronic control unit and wire.

8. Vehicles without protection cannot stop in the maintenance area of body, because splashed sparks can cause

fire and damage the painted surface and glass.

9. Please polish and weld carefully nearby the fuel tank or components with fuel. Please dismantle all

components which may influence safety.

10. Do not weld, perform hard soldering and soldering on any component of air-conditioning system with

refrigerant and do not weld other components which can make the temperature of components of
air-conditioning system rise, because it may result in explosion of air-conditioning system. If it must be soft
in the refrigerant

If electrically welding close to the pipe, the refrigerant must be recovered; because invisible ultraviolet
generated by electric welding penetrates through the refrigerant hose, the refrigerant decays.

11. When operating safety airbag system or correcting vehicle body, battery grounding wire must be

disconnected ambient temperature around safety airbag part must not exceed 100℃(212 ºF).

12.12.2.2 State of Components

Before the repaired vehicles or components are sent to the paint plant for spray paint, the surface shall be smooth
and the seam shall be filled. The surface shall be polished by sand paper. The preparatory process shall be finished
by metaler, The components of body and floor are mainly formed by cold stamping of steel plate. Therefore, the
damaged positions caused by accidents shall be recovered through the same method. If the damaged positions
cannot be recovered as original shape, please correct the adjacent position, dismantle the damaged positions and
replace it according to parts integrity. Do not cut single part, because after the cutting and welding, the rigidity,
travel safety and maintainability of complete vehicle will be influenced.

12.12.2.3 Description of Varieties of Welding

Common varieties of welding are spot welding, gas shield welding and brazing. Number of spots cannot be
reduced when spot welding is performed. Generally speaking, when spot welding equipment cannot be performed,
plug welding can be performed with gas shield welding after drilling. When spot welding is adopted for
connecting three layers of plates, please replace the outer plate. The welding spot shall be placed on the original
welding spot. When spot welding is performed, single row of welded seam, double rows of welded seam and
double rows offset welded seam can be generated. When gas shield welding is adopted, lap welded seam,
continuous welded seam and continuous welded seam (interrupted) can be generated. Brazing is usually used for
welding and repairing the area with strength of extension not strong enough and low component thickness.

12.12.2.4 Anti-corrosion Treatment

1. The standard anti-corrosive coating shall be recovered by approved materials after maintenance.

2. Before sealing, all inside and outside of welded seam shall be applied with primer.

3. Metal plates with primer shall be applied with sealant.

4. Lap metal panels, metal edges, butt-jointed welded seam and welded seam shall be sealed up with sealant.

5. The vehicle base plate shall be applied with long-acting protective agent.

6. After the finished paint is painted, please treat the cavity in the maintenance area with cavity protective

materials.

7. After the cavity protective materials are dried, please clean outlet.

12.12.2.5 Environmentally Friendly Disposal Approach for Scrapped Components

1. After the maintenance for vehicle, please collect the waste materials according to their types.

2. Classify the waste materials to inspect whether they can be used again.
