| Abstract: | In this paper,the weldability of SiCw/6061Al composites by high- energy laser is explored and the characteristics of the microstructure and crystallization in its welded joints is comprehensively analyzed. Authors investigated the effect of welding conditions on appearance and properties of weld.The experimental results indicated that for SiCw/6061Al matrix composite material,high energy laser welding is able to realize its weld joining and the welded joints shows excellent appearance without the defects of gas pores and cracks.Finally,the authors come to a conclusion that it is necessary to choose appropriate welding parameter and additives for wel- ding composites. |
