Repairing general conditions
The replacement (reparation) operations of the weldable elements described in this chapter
are specified subject to: cutting out of the parts to be replaced, access to the welded elements,
tools and checking devices accessibility , etc.
In case the vehicle body has suffered important deformations it is recommended the straight-
ening of the damaged body elements, by means of some hydraulic presses.
For this range of vehicles, the elements resistance structure which are affecting the vehicle
s ecurity, are not to be partially replaced (not to be cut), but entirely.
After welding detaching, the body elements must remain straight, without breakage or cracks,
the possible holes being covered out with filling material or by tinning. The body elements sur-
faces are to be pickled ( to eliminate possible oxidation marks), dried and initially applied a paint
layer. The electric welding detaching of the body elements, may be performed as follows:
- with a well sharpen c hisel, t his method may lead t o parts de formation or e ven pa rts
breaking. - by using some extractors equipped with steel cutter type Brendeo or Pickvant (max. 6
mm) having the cutting head shaped as shown in pict.1.
1. Centering point
2. Sharpen slope
3. Drill acting edges
4. Gap for catching the welding material
P = aprox. 0.4 mm
Whatever m ethod is used, the remaining element must be in good order and to a llow per-
forming of a good quality welding point.
The plates cutting it is recommended to be performed (subject of importance and thickness)
using manual scissors or pneumatic portable tools for plates cutting. During cutting or welding of the body elements it is necessary to protect the electric wiring
from the interior of the body structure. The cutting, welding, or strengthening operation done on body welded elements, are to be
performed on body checking/ straightening benches recommended by the producer.
IMP ORTANT !
When removing or straightening the body resistance elements, it i s forbidden the
total or partial heating, in order to avoid the mechanical resistance and metal elastic-
ity de creasing.

ldin g types and parameters
At the reparation of the welded body elements, three welding categories may be used: protection
gas welding (CO2), electric spot-welding and filling materials (built-up) welding (oxyacetylene).
At the built-u p welding, it is recommended that flame must be slightly inclined so that arch can be seen
and the flame extremity to be maintained at aprox. 5 mm from the part to be welded.
1. Spot welding resistive parameters for steel plates with carbon content C < 0,15 %.
R EMARK :

2. We lding parame ters for the welding in protection gas for carbon steel plates or low-allo ye d steel.
