              Body assembly                                                                                       IN

              Sheet metal
              1. Sheet metal operation process                                                                    DI
              a. Damage  confirmation.  Clean  the  damaged  part  and  confirm  the  degree  of  damage,  to  define  the  repair
              method.                                                                                             EG
              b. Remove the sheet metal part. Remove the damaged sheet metal part from the original body with cutting or
              other methods.
                                                                                                                  TR
              c. Level the sheet metal part. Based on the damage degree of sheet metal part, level the sheet metal part with
              the appropriate sheet metal tools and fine-tune the surface flatness of sheet metal part.
                                                                                                                  AX
              d. Carry  out  the  annealing  treatment.  Carry  out  the  annealing  treatment,  to  restore  the  original  shape  and
              thickness of the sheet metal part and relief the tensile or extrusion stress, so as to maintain the rigidity and
                                                                                                                  FR
              strength of sheet metal part.
              e. Apply the epoxy paint. The epoxy paint inside of the sheet metal part may fall off or be damaged due to the
              hammering process, so it should be applied with a layer of epoxy paint.                             ST

              The above sheet metal operation process applies to the sheet metal parts with a small degree of damage;
              if the body is collided seriously, and the frame is damaged, the frame and the body should be correcred,   BR
              the operation would be more difficult.
                                                                                                                  BW
