    • Abstract
  • Selecting the stainless steel self-shielded flux cored wire as research subject, the pictures of droplet and electric arc were taken using high-speed photography and force on the droplet was analyzed during MAG surfacing intervened by laser. The results showed that laser intervening changed melted state of end of the wire. The melted states were partial melting, half melting and dead melting. Laser intervening made electromagnetic pinch force and the components of plasma flow force in axial line of wire increase, which were beneficial to droplet transfer. Laser intervening made surface tension force reduce, which was beneficial to tessellate droplet. Laser intervening increased atmosphere dynamics and promoted droplet transfer in appropriate laser parameter. The track of droplet transfer had three patterns which were right shaft transfer, left shaft transfer and along the shaft transfer.
