| Abstract: | Current research situation of fusion welding, especially high energy density welding, of A1-MMCs Reinforced with SiCp,also known as SiCp/Al, is reviewed. Main problems associated with fusion welding,such as weld forming, formation of A14 C3 compounds and weld porosity, are analyzed in terms of formation mechanism, influencing factors and preventing measures. Recommendations are subsequently made for future research. |
