6.5 Aluminium welding
Inert gas welding (MIG) is a technique used both at the factory
and in the workshop.
The shielding gas used is argon.
– Remove underseal and paint from components prior to weld‐
ing.
– Then use a stainless steel brush to remove oxide layer (ap‐
prox. 40 mm on both sides).
– Weld seams must always be continued around section cor‐
ners to prevent crack formation.
