REPLACING SHEET METAL
Generally, a severely damaged panel will be
replaced or repaired by cutting out the damaged area
and replacing it with sheet metal. Should you have to
repair a heavily damaged body panel, there are a few
things you should consider before starting the job.
The first and most important consideration is to
determine the direction of force that caused the
damage. This will enable you to use the hydraulic jack
and its attachments to push the panels back into a near
original position. At the same time, the braces holding
the sheet metal will move back to their original
position and allow access to any bolts and fasteners
that must be removed to disassemble the damaged
body parts. Once you have reached this point, it must
be determined if the damaged panel is to be repaired or
replaced.
If you decide to replace the damaged panel, make
sure any braces that support the panel are ordered also.
New braces will assist in aligning the new panels with
the rest of the body. Should only a portion of the
damaged panel be replaced, a oxygas cutting and
welding outfit (fig. 8-66) will be required to remove
the damaged portion and weld the new sheet metal into
position.
NOTE
Complete instructions on the use and care
of oxygas cutting and welding outfit are
contained in the current edition of the
Steelworker training manuals. Consult these
manuals for the proper method for adjusting
and using the cutting and welding tips.
