1.1 REPAIRS TO THE CHASSIS
-
Any welding, aligning, drilling and
wheelbase alteration activities that are not
described in this workshop manual, or in
any of the latest releases of DAF’s Chassis
Guidelines, must be authorised by DAF.
-
Following chassis repair, the cause of the
chassis damage should be rectified.
Welding
-
Chassis welding may only be carried out by
welders holding a valid EN 287-1 certificate.
-
For welding operations on steel grade
KF 375 chassis, the welding electrode must
meet one of the following standards:
ISO 2560
:
E 515 B24 (H)
DIN 1913
(January 1976)
:
E 5155 B10
EN 499
-
Slag inclusions and other contaminations in
the weld are totally unacceptable.
Note:
Welding on chassis constructed of
high-tensile strength steel grades KF 420,
KF 500 en KF 600 is not recommended.
If, however, you do wish to weld a
high-tensile strength steel chassis, contact
must always first be sought with DAF.
The welding electrode must meet the
DIN 8529 standard:
EY 5066 1.5 NiNoB
