11.4.1. Repair of sidewalls of a body

At repair of sidewalls of a body the following works can be carried out:

Fig. 11.27. Ways of connection when replacing door panels

1) replacement of panels of doors (fig. 11.27), for what:

— to a welding point soshlifuyta on the strengthening element and a door arch;

— to a soshlifuyta of an edge of the door panel;

— remove the door panel;

— grind and align the interfaced surfaces;

— apply glue on places of a zavaltsovka and on inside of the details of the door panel and a frame of a door put for welding;

— adjust the door panel, put welding clamps;

— bend edges;

— weld on the strengthening element contact spot welding;

— weld edge of the panel a prikhvatochny seam;

— weld electrorivets at a door arch;

— condense edge of a door;

2) replacement of the strengthening element and threshold (fig. 11.28), for what:

— replace the strengthening element assembled;

— from the outer side the threshold of a door connects to a Torpedo sidewall under a loop, and at a rack In — at a bend;

— weld continuous seams;

— weld contact spot welding at a doorway and at the lower edge of the panel of a floor;

— weld a threshold electrorivets from below up;

3) replacement of a rack And (a general view in fig. 11.29) and the strengthening element, for what:

— cut out the damaged part;

— adjust the interfaced surfaces;

— apply welding primer;

— drill openings for electrorivets;

— adjust and fix the strengthening Torpedo sidewall element;

— prepare for welding by electrorivets sites on which it is impossible to execute contact spot welding;

— adjust a rack And;

— cut the edges;

Fig. 11.30. Ways of connection of the replaced details

— weld (fig. 11.30);

— around a loop and fastening of the limiter of opening of a door execute welding by electrorivets;

Fig. 11.31. Ways of connection of the strengthening element of the top longeron

4) installation of the strengthening element of the top longeron (fig. 11.31), for what:

— fix the strengthening element of the top longeron;

— weld the strengthening element of the top longeron;

Fig. 11.32. The body details forming a rack In: 1 — a sidewall; 2 — a rack In; 3 — the amplifier of a rack In; 4 — the internal panel of a beam of a roof; 5, 6 — internal panels are resistant In (top and lower respectively)

5) replacement of knot of a rack In (consisting of five components, fig. 11.32), for what:

— previously cut off the replacing part of a beam of a roof from a rack In;

— cut off the replacing part of a sidewall of a body, so that it could define the provision of a rack In;

Fig. 11.33. A way of cutting of a rack In on the repaired body under welding: And = 30 mm; In = 30 mm; With = 30 mm

— on the car remove a rack In (from above — as shown in fig. 11.33, from below — on welding connection);

— establish a rack In inside sidewalls of a body;

— fix a body sidewall on the car;

— weld a rack In on the internal panel of a threshold a prikhvatochny seam;

— remove a body sidewall, leave a rack In on the place;

— cut off both panels at a roof beam, weld a continuous seam;

Fig. 11.34. Ways of connection when replacing a rack In

— weld the lower section of a rack electrorivets (fig. 11.34);

— apply glue on a rack In;

NOTE Before installation of external section of a rack In it it has to be prepared for pasting by epoxy glue.

— put a glue layer on the site of 70 mm from a roof beam to 130 mm from fastening of the top loop;

— put a body sidewall over the strengthening rack element In;

— adjust and cut off a joint, weld continuous a seam;

— cut off and weld threshold joints;

— weld the lower part of a threshold on a threshold beam electrorivets;

— execute other welded seams contact spot welding;

— put an internal part of a rack In, weld contact spot welding;

— weld the top joint a continuous seam;

— grind welded seams.

NOTE Do not forget to rearrange a plate with a carving in a lock clamp cell!

PREVENTION Do not place a welding joint at the stuck together site.
