Welding with Pulsed Lasers Protects Temperature-Sensitive Materials
LA JOLLA, Calif., Aug. 29, 2019 — A new ceramic welding technology developed by engineers at the University of California, San Diego and the University of California, Riverside uses a series of short, ultrafast laser pulses to melt ceramic materials along the interface between two ceramic parts and fuse them together. Heat builds up only at the interface, so the melting is localized. The researchers call their method “ultrafast pulsed laser welding.” To make this approach work, the researchers had to optimize
