Installing Roof Frame Reinforcement

Information 

Determine the position of the new part and secure with tensioning clamps.

When butt welding body sheet panels with a sheet thickness of > 1.5 mm, there must be a welding slit width s = 1 x sheet thickness to guarantee the required welding quality (welding through).
