1.14 Preparing and cleaning areas for welding
Often, for the sake of convenience or due to a shortage of time,
joint areas are not adequately prepared and cleaned correctly,
in spite of the fact that these preliminary procedures are vital
for a perfect, high quality weld.
The quality of a weld seam may be compromised so severely
as a result of inadequate preparation that it may even need to
be removed for safety and the weld repeated. The time saved
in terms of preparation is not even remotely comparable to the
amount of time wasted in having to redo a weld.
The following procedures are necessary:
• The weld points on all parts of the bodywork must be ground
(removing the paint).
• Before welding, remove the layer of oxide with a stainless
steel wire brush.
• Before welding, clean the welding area with a degreasing
detergent or acetone.
NOTE!
Failure to clean weld areas adequately may severely
compromise the strength of the weld itself by promoting
the development of porosity.
Caution!
Before welding, fit all attached parts (lights, radiator
grille, engine compartment lid etc.)!
