Numerical Investigation of Keyhole Depth Formation in Micro Welding of Copper with 1030 nm and 515 n and 515 nm laser radiation is analyzed. An instructive consideration of the keyhole front in the upper keyhole part is presented and three absorption mechanisms that affect the geometrical form of the keyhole are identified: direct absorption, absorption contributions due to multiple reflections, adissolution 发表于 2025-3-27 08:22:53
