14. Inner B-pillar (1) (areas K, L).

    Inert gas weld in intervals and allow welding area to cool down in between.

    Heat distortion is thus reduced.

15. Surface-grind inert gas welds at inner B-pillar (1) (areas K, L).

    

    Grind down flat on contact surfaces on B-pillar paneling and beaded area only.

16. Clean weld joints no longer accessible after installing B-pillar reinforcement and coat with zinc dust paint.
17. Inner B-pillar (1) (area O).

    Inert gas weld in intervals and allow welding area to cool down in between.

    Heat distortion is thus reduced.

18. Surface-grind inert gas weld at inner B-pillar (1) (area O).

    

    Grind down flat on contact surfaces on B-pillar paneling and beaded area only.

19. Clean weld joints no longer accessible after installing B-pillar reinforcement and coat with zinc dust paint.
