Provide a reasonable explanation for the following observation: a welded component made of Al 6061-T6 alloy is routinely found to deform plastically first in the region adjacent to the weld joint despite the fact that the stress is nominally the same everywhere in the component. What solution would you propose to fix this problem, assuming that the weld joint cannot be eliminated from the design?
