Laser welding modes: conduction, transition, & keyhole welding

Posted by Geoff Shannon on Tue, Jan 19, 2016 @ 12:30 PM

The laser is a high energy density process that provides a unique welding capability – maximum penetration with minimal heat input. There are three basic weld modes, which correspond to the level of peak power density contained within the focus spot size: conduction mode, transition keyhole mode, and penetration or keyhole mode. Figure 1 is a graphic illustration of the three weld modes.
