| High-resistance body panel |
| Our vehicles are increasingly equipped with high-resistance
panels. The fields of application of these panels may be consulted
in → Rep. gr.00. |
| What is a high-resistance panel? |
| Apparently a normal plate, but due to its different alloys
it features an elasticity limit that is higher than that of the common
body panels. In other words, by exerting the same force on the panel,
deformation „dents“on the high-resistance panel is not
as deep as on a common panel. |
| What should be taken into account when unwrinkling? |
| The unwrinkling operation is carried out with conventional
tools. Due to the higher resistance to deformation, there is a higher
resistance, which is why it will be necessary to apply more force.
If the folds are undented, the material may break. |
| What should be taken into account when aligning
with the alignment bracket or with the hydraulic press? |
| Due to the higher resistance of the panels, it is necessary
to stretch even more than on a common panel, before the panel is in
the desired position. Due to the higher distribution of force, although
the same happens with the common welded panels, to high-resistance
panels, it is also necessary to apply more force. In order to prevent
the panel from yielding or cracking, provide additional anchorage. |
WARNING | t
| If the high-resistance panel stretches too much, the length
may be larger than desired! |
| t
| For safety reasons, just as with common panels, it is also
prohibited to heat the high-resistance panels when undenting! |
|
| What should be taken into account when repainting? |
| If the high-resistance panel heats too fast due to the drying
equipment, the panel will stretch. If, however, the panel is connected
to the reinforcement located in the back through spot welding or through
bonding, dents will appear at these spots that will remain visible
after cooling. For this reason, the drying equipment must be slowly
placed in maximum power. Drying may be done in the drying cabin without
any danger. |
