Pulse laser was used to weld SiCw/6061A1 composite in this paper. The effects of parameters such as output power, pulse frequency and surface treatment condition on strength of welded joint were studied. The results indicated that: output power of laser beam is the most important parameter affecting quality of Weld. Interface reaction between SiC and aluminium matrix can be restrained by controlling output power of laser beam, thus the welding of aluminium matrix composite SiCw/6061A1 was successfully realized by using pulse laser.
