The example methods and apparatus reduce and/or eliminate adverse effects of welding work pieces having dissimilar compositions. An example method includes depositing a first weld layer on a first end of a first work piece. The first work piece has a first content of a metallic element and the first weld layer has a second content of the metallic element higher than the first content. The example method includes depositing a second weld layer between the first weld layer and a second end of a second work piece to couple the first work piece to the second work piece. The second weld layer has a third content of the metallic element higher than the second content, and the second work piece has a fourth content of the metallic element higher than the first content.
