Welding in

Note

♦

In the area of the A, B and C-pillars, high tensile, highest tensile and hot formed steels are used. The weld

flanges in these areas are about 13mm wide.

♦

If spot welds are located at the edge of hot formed steel panels, the high temperature will cause the bond

between the panels to change, which will subsequently have an effect on crash safety.

Therefore, locate spot welds as close to the centre as possible.
• Dimension -a- of 8mm can be achieved using angled welding

tips.

– Adapt new part with vehicle positioned on alignment bracket

set and fix in place.

– Check fit with bolt-on parts.
