Abstract
A fracture-resistant charge air cooler header is provided. The internal side of the header includes, at select locations most likely to sustain a fracture, a reinforcing weld bead or 'nugget' of sufficient height to create a section modulus change. The weld bead is preferably formed from a highly ductile alloy, such as AA 1100 aluminum alloy, and may surround either a portion of the header component associated with a tube or its entire perimeter.
