|
|
16.
|

|
|
17.
|
Drill holes for plug welding in the spare part, the inside of the B-pillar.
|
|
18.
|
Grind all surfaces that are to be plug welded.
|
|
19.
|
Apply welding primer to all surfaces that are to be plug or spot welded.
|
|
20.
|
Align the inside of the B-pillar using the earlier markings.
|
|
21.
|
Weld in the inside of the B-pillar at the lower edge. Grind in the welds
|
|
22.
|
Weld in the inside of the B-pillar at the upper edge. Grind in the welds.
|
|
23.
|

|
|
24.
|
Align the B-pillar reinforcement using the earlier markings.
|
|
25.
|

|
|
26.
|
Spot weld and plug weld the lower section of the B-pillar reinforcement.
|
|
28.
|
Cut the new outer panel so that it corresponds with the earlier cutting work.
|
|
29.
|
Drill holes for plug welding on the bottom and side of the outer panel.
|
|
30.
|
Grind all surfaces that are to be welded.
|
|
31.
|
Apply welding primer to all surfaces that are to be plug or spot welded.
|
|
32.
|
Align the outer panel by inserting it under the roof, rear and front sills.
|
|
33.
|
Plug weld, all-weld and seam weld the spare part in at the upper edge against the roof. Grind in the welds.
|
|
34.
|
Spot-weld the spare part.
|
|
35.
|
Tap down the edge of the roof against the outer panel and the B-pillar reinforcement. Plug weld the drilled-out holes.
|
|
36.
|
Securely all-weld the front sill reinforcement.
|
|
37.
|
All-weld the rear sill.
|
|
38.
|
All-weld the upper section of the B-pillar.
|
