Aluminum based MMCs have greater strength; good wear resistance and excellent elevated temperature properties. Alimnium based MMCs are being widely used in Automotive and Aerospace industries. In spite of the advantages of MMCs as described above they are not widely used due to lack of their applicability to tertiary process like welding. However, the presence of reinforcement causes difficulties in welding of these materials. Hence the present study is aimed at optimization of welding parameters for weld strength and examination of difficulties/defects during welding of these materials.

Abstract


Aluminum based MMCs have greater strength; good wear resistance and excellent elevated temperature properties. Alimnium based MMCs are being widely used in Automotive and Aerospace industries. In spite of the advantages of MMCs as described above they are not widely used due to lack of their applicability to tertiary process like welding. However, the presence of reinforcement causes difficulties in welding of these materials. Hence the present study is aimed at optimization of welding parameters for weld strength and examination of difficulties/defects during welding of these materials.
