Immediately￿before￿welding,￿clean
the￿weld￿area￿to￿ensure￿there￿are￿no
contaminants￿in￿the￿weld￿zone.
Only￿finish￿welds￿that￿are￿visible￿or￿interfere￿with
other￿parts.
When￿an￿aluminum￿part￿is￿welded,￿not￿all
welds￿require￿dressing.￿When￿determining
if￿a￿weld￿should￿be dressed:
are￿the￿welds￿visible?￿If￿the￿welds
•
are￿not￿visible,￿and￿will￿not
interfere￿with￿other￿parts￿being
attached,￿dressing￿may￿not￿be
necessary.

Welded￿Panel￿Replacement
When￿grinding,￿do￿not￿use￿abrasives￿that￿were￿used
on￿steel￿to￿avoid￿cross￿contamination.
When￿removing￿a￿welded￿panel:
removal￿is￿done￿similar￿to￿that￿of
•
steel￿vehicles,￿but￿caution￿should
be￿used￿as￿aluminum￿material￿will
be￿removed ￿faster￿than￿steel.
remember,￿when￿grinding￿or
•
sanding￿aluminum,￿slower￿speeds
with￿light￿pressure￿are￿preferred.
