Welding 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-up 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 %.
REMARK :
1 period = 1/50 part of a second.
2. Welding parameters for the welding in protection gas for carbon steel plates or low-alloyed steel.

Collision diagnosis
During the vehicle exploitation, the carriage body may suffer different distortions, that lead
many times to the wheels setting angles modification, body elements breakage, vibrations or even
mechanical parts wear.
In these conditions, before performing the vehicle body reparation, some checking is necessary:
Visual checking - consisting in the examination of the mechanical elements attachments and
of the distortions occurring in the vehicle damaged areas.
Checking with the bar (control gauge) – consisting in comparing the measurements done
in symmetric points.
The geometry checking of the rolling transmissions – this checking is the only one enabling to
find out if the body damage was not affecting the vehicle road behavior.
IMPORTANT :
This checking must be not ignored, except some border-line cases, the checking of
the rolling transmissions leading to the identification of the distortions occurred further
to an accident.

Collision diagnosis
CENTRAL PART CHECKING
The central part checking is performed in the purpose to establish if one of the distortions is
not affecting this part of the floor, from where the checking starts.
Compare the followings lengths : EI = FJ ; EJ = FI .
FRONT LONGITUDINAL GIRDERS CHECKING
Compare the followings lengths: CG = DH; CH = DG.
If the lengths (CH - DG) and the diagonals (CG – DH) are not identical, check again the
point (3).
If points (1) and (2) are good, the front axle angles may be checked.
