Weld operations
●
Thoroughly remove paint and rust from the chassis where welds will be made, as well as all parts that will be covered by rein-
forcements.
●
Cut the side members with a skewed or vertical cut. The side members must not be cut at the points where the chassis con-
tour and width changes or where stress is greater (e.g. spring mounts). The cutting line must not go through the holes on the
side member (see Figure 2.4).

●
Make a 60 degree bevel cut on the internal part of the side member of the parts to join, for the entire length of the weld area
(see Figure 2.5).

●
Arc weld the area with multiple steps and use base electrodes that are thoroughly dried.
Avoid power overloads; the welds must be free of marginal incisions and slag.
●
Start from the opposite end and weld as in the previous item.
●
Let the side members cool slowly and in a uniform fashion. No cooling with air jets, water or other means is allowed.
●
Grind off the excess material.
●
Mount steel corner reinforcements that have the same characteristics as the chassis; the minimum indicative sizes are shown in
Figure 2.3.
Reinforcement anchorage must regard only the vertical rib of the side member and can be realised with a weld bead, staples,
bolts or nails (even Huck nails).
Area and length of the weld bead, number and distribution of staples, number of nails of bolts must be adequate to transmit
the bending and shearing moments.
●
Once work is complete, use anti-rust protection (see Paragraph"Added or Modified Parts" (
