Laser oscillating welding of AZ91 and Ti-6Al-4V was carried out and the influence of oscillating parameters on morphology and mechanical property was investigated. The joint strength obtained with beam oscillating was enhanced compared that without oscillating. With oscillating frequency increased, welding width of Mg improved while the melting amount of Ti decreased. The tensile strength improved initially and then decreased when oscillating frequency increased.
