7.2 Welding guidelines for axle beams

G Geenneerraall
Material: S 355
When installing trailer axles, it may be necessary to
subsequently weld components onto the axle beam.
BPW axles are therefore made of weldable material.
H
The axle beams do not need to be heated prior to
1/4 H welding.
The load-bearing strength and perfect functioning of
Weld length
the BPW axles are not reduced by welding work if
max. 200 the following points are observed.

= adm. welding zones

W Weellddiinngg mmeetthhooddss

Inert gas welding
Welding wire quality G 4 Si 1 (DIN EN 440)
Manual arc welding
Rod electrodes E 46 2 (DIN EN 499)

The mechanical quality values must correspond
to the base material S 460.
Weld length Max. weld thickness a 5 (DIN EN ISO 5817)
60° max. 200 Avoid end craters and undercuts.

M Miisscceellllaanneeoouuss::

Do not alter the camber or tracking of the axles
except within BPW tolerances.
Observe the welding zones and weld lengths
shown in the adjacent diagram.

The trailing arms, air bags and plastic pipes
must be protected against flying sparks and
weld spatter during all welding work. The earth
terminal must never be attached to the trailing
arm or the hub. Do not perform any welding on
the trailing arms!
