Special Issue Information

Dear Colleagues,

The laser welding is increasingly used in a variety of industries, e.g., rail transportation, automotive, marine, power plants, biomedical micro-electro-mechanical systems (MEMS), BioMEMS devices, etc. This Special Issue is focused on the challenges and opportunities faced by laser intelligent welding and quality assessment. Better understanding of the intelligent algorithms and quality assessment methodologies used in the laser welding is of great significance for achieving the welding process with high quality. Multi-disciplinary discussion and debate about the welding intelligent algorithms, welding process, welding quality assessment methodologies and welded joints performance are encouraged.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: Laser welding; Welding intelligent algorithms; Welding modeling; Welded joints performance.    

I look forward to receiving your contributions.

Dr. Yuewei Ai
Guest Editor

The energy distribution in molten pool is highly related to the quality of the weld formation in aluminum alloy welding. The forming defects in the weld are often improved by adjusting the molten pool dynamic behaviors affected by energy distribution. Therefore, the energy distribution characteristics in the molten pool during the welding of aluminum alloy with oscillating laser in the “∞” shaped path are explored in this paper. The pore defects are found to be greatly reduced in welds from the oscillating laser welding of aluminum alloy compared to those from non-oscillating laser welding. The corresponding distribution characteristics of energy in the molten pool of welding with oscillating laser are obtained and analyzed. The dynamic behaviors and forming process of welds under welding conditions of different distribution characteristics of energy in the molten pool are discussed. The obtained results are in good agreement with the experimental results. Therefore, the proposed method can provide the desired energy distribution for stable dynamic behaviors of molten pool to improve welding quality. Full article
