摘要: Laser beam welding is very much popular in Microsystems technology by its precise parameters. Generally it characterized transient nature and short duration of the process. For real-time applications, model should be computationally efficient relate critical but unmeasurable variables such as weld bead penetration to easily measurable surface temperature. So for accurate real time tracking inspecting, wide range reliable sensor, CMOS, CCD, Infrared, Ultra violet Photodiode based with high performance are extremely demanded laser Penetration depth most important parameter fulfill criteria expected welding. This article describes research review on online measurement techniques use identify quality (i.e. depth) control system geometry pool prevent defects
