2. Repairing and correcting defects
Welding is used to fill surface cavities, while impregnation is used to restore watertightness.
2.1 Welding
-
Autogenous welding is used
.[B 7 730] The filler metal, in the form of rod or wire, must have a composition similar or identical to that of the part to be repaired. These products are not always commercially available, and the foundryman is often obliged to manufacture them himself.
Oxyacetylene soldering is no longer widely used, because of the risk of creating flux inclusions.
Argon-covered arc welding has become the preferred method. The...

Patents
French National Institute of Industrial Property (INPI)
A large number of patents relating to aluminum alloy casting have been filed or are in the process of being filed around the world; an exhaustive list is virtually impossible to compile due to the constant filing of new patents, which means that they have to be constantly updated.
