The feasibility of repair of aluminum alloy castings that were already heat treated andmachinedis questionable because of stresses and deformations likely to develop during welding. An example of such a repair performed by developing a special procedure withelectron beam weldingis reported in this page...

This weld configuration is representative of seam welds that require a third, repair weld pass. The material properties adopted are largely those reported in Table 3 but some changes are introduced to incorporate the information provided by the microstructural hardness map. Namely, the ASTM-A370 ...
This study aimed at i) determining any combined effects of the presence of whey protein (WP) and welding-induced weaknesses on corrosion and metal release, and ii) determining the appropriate welding procedure and filler metal (316 L, 309 L, 312). All weld metals (WMs) showed a ...

For example, when foreign object damage occurs to the airfoil, the resulting void is clearly apparent and therefore serves as the focus of the repair procedure. However, the impact may also leave residual cracks and other weaknesses in the region of the airfoil surrounding the void that will no...
Once an impeller is identified for repair, it is prepared for welding, or other kind, of repair. This may include procedures known in the industry such as grit blasting and degreasing. At this point, impeller10is ready to be secured in the restraining fixture. The restraining fixture is disa...
