5.2 Welding work
The legal stipulations regarding the transport and
storage of airbag units must be observed.
All laws governing explosive substances must be
complied with.
The following safety measures must be observed to
prevent damage to components caused by
overvoltage during welding work:
• Disconnect the positive and negative terminals
from the battery and cover them.
• Connect the welding-unit ground terminal directly
to the part to be welded.
• Do not touch electronic component housings
(e.g. control modules) and electric lines with the
welding electrode or the ground contact clamp of
the welding unit.
• Before welding, cover spring to protect them from
welding spatter. Do not touch springs with welding
electrodes or welding tongs.
• Avoid welding work on inaccessible cavities in the
cab.
• Welds must be ground down and reinforced with
angular profiles to prevent notching from welding
penetration.
• Avoid welds in bends.
• The distance from a weld to the outer edge should
always be at least 15 mm.
• Avoid defects such as deposited metal cracking,
toe crack, blow holes, slag inclusion, under cut,
poor penetration, etc.
a Risk of injury
Welding work in the vicinity of the airbags can
cause the restraint system to malfunction.
Welding work near the airbags is strictly forbidden.
The airbag could be triggered or may no longer
function correctly.
! Property damage
Do not connect the arc welder ground clamp to
assemblies such as the motor generator or axles.
Welding work is not permitted on assemblies such
as the motor generator, axles, etc.
