Investigation of conduction to keyhole mode transition [PDF]

, 2012
There are two very distinct welding modes in laser welding, keyhole and conduction mode. The characteristics of keyhole laser welding; mainly high penetration, high productivity and high aspect ratio have led the industry to focus more on this mode.
