<p>A method is disclosed for welding a first metal to a Ti-6246 alloy airfoil. The method consists of depositing weld metal by fusion welding and reshaping the airfoil to predetermined dimensions. A post weld heat treatment is applied to relieve residual stresses. Surface treatment such as laser shock peening introduces residual surface compressive stresses to enhance the mechanical integrity of the airfoil.</p>
