Drilling the Chassis
2.3.4 Welding the Chassis
All frame welding must be carried out after authorisation from IVECO.They must then be carried
out scrupulously following the instructions given below.
NOTE
!
Welding operations must only be carried out by specialist, trained personnel, using suitable equipment
and in a perfectly workmanlike manner (see norms EN 287). Any intervention on the system not car-
ried out as per instructions provided by IVECO or carried out by unskilled staff, might severely damage
the on-board systems, thus adversely affecting vehicle operation safety and efficiency and causing dam-
ages not covered by guarantee contract.
In case of arc welding, strictly follow instructions below in order to protect electric units and ECUs:
- before disconnecting power cables, check for no loads engaged;
- in case an electric switch is installed (main contactor) wait for cycle end;
- disconnect negative power pole;
- disconnect positive power pole without connecting it to ground and DO NOT short circuit it with negative pole;
- disconnect ECUs connectors, operate carefully and do not touch ECU connector pins;
- In case of welding next ECU, disconnect it from vehicle;
- connect welding machine ground directly on part to be welded;
- protect plastic material pipes agains t heat sources and disassemble, if required:
- in case of welding near leaf springs or air springs against welding spatters, carefully protect surfaces;
- avoid electrode o r gun contac t w ith spring leaves;
Operations for welding preparation
As part of the procedure it will be necessary to remove the paint and deoxidise the parts of the chassis that are affected by the
welding operation as well as those parts which may have to be covered by possible reinforcements. When work has been completed
the modified part must be protected with adequate rustproofing (see point 2.2.2).
a) Cut the side members with a diagonal or vertical cut. (We recommend that the diagonal cut be used particularly for the section
between the wheelbase) Cuts are not permitted in areas in which the profile of the side member as well as the chassis width
chan ge or in those where there is a high concent ration of st resses (e.g. spring brackets). The cuts must not be made throu gh
the holes present in the side member (see Figure 2.2).
