Abstract
A process of welding an article and a welded turbine blade are disclosed. The process includes fusion welding over a primary symmetry line determined from a center of gravity on a first side of the article or blade and fusion welding over the primary symmetry line determined from the center of gravity on a second side of the article or blade. The fusion treating includes multiple fusion treatments.

A process of welding a turbine blade, the process comprising:
- identifying the center of gravity of the turbine blade;
- fusion welding a suction side along a first path extending over a primary symmetry line determined from the center of gravity of the turbine blade;
- and
- fusion welding a pressure side along a second path extending over the primary symmetry line determined from the center of gravity of the turbine blade;
- wherein the fusion welding includes multiple fusion welds.
A process of welding a non-uniform article, the process comprising:
- fusion welding a first side along a first path extending over a primary symmetry line determined from a center of gravity of the non-uniform article;
- fusion welding a second side along a second path over the primary symmetry line determined from the center of gravity of the non-uniform article, the first side opposing the second side;
- and
- identifying the center of gravity by suspending a template of an exact cross section of the non-uniform article from a first point proximal to the first side and suspending the non-uniform article from a second point proximal to an edge extending between the first side and the second side;
- wherein the fusion welding includes multiple fusion welding processes.
A turbine blade, comprising:
- a pressure side and a suction side;
- a first overlap fusion welding region on the pressure side extending over a primary symmetry line determined from a center of gravity of the turbine blade;
- and
- a second overlap fusion welded region on the suction side extending over the primary symmetry line determined from the center of gravity of the turbine blade;
- wherein the first overlap fusion welding region and the second overlap fusion welding region are formed by multiple fusion welding processes.
