Abstract
This chapter introduces the time-dependent keyhole and weld pool dynamics in laser welding with filler wires. Mathematical models of the welding process including wire feeding model, boundary conditions, and keyhole and weld pool coupling model are presented. Keyhole and weld pool behaviors under different wire transfer modes including droplet and continuous transfer are discussed in detail. The oscillation mechanisms of keyhole and weld pool in laser welding with filler wires are investigated. The time dependent dilution behaviors of weld pool by the filler wire are also studied.
