This paper reviews the application of different laser types—CO₂, diode, Nd:YAG, and fiber lasers—in polymer welding, highlighting their characteristics, advantages, and limitations. It emphasizes the critical influence of process parameters such as laser power, scanning speed, number of scans, and beam diameter on weld quality, strength, and stability. The study concludes that achieving high-quality polymer laser welding requires both precise laser selection and fine-tuned parameter control, with future developments expected toward higher precision and broader material compatibility.

Laser oscillation welding introduces beam movement during the welding process to improve molten pool dynamics, helping reduce defects such as porosity, sidewall lack of fusion, and hot cracks. By enhancing keyhole stability, improving energy distribution, and promoting grain refinement, it achieves higher-quality welds. This technique broadens the scope of laser welding applications, allowing efficient and precise welding for large and wide-seam components.

This study investigates how different laser oscillation paths—N-mode, C-mode, and I-mode—affect pore formation during the laser welding of medium-thickness aluminum alloys.
