Tangential airflow as a kind of environmental factors can impact on the laser irradiation. In recent years, the tangential airflow effects on laser irradiation are extensively studied by some scholars at home and abroad, including the influence of different natures of the airflow environment, different intensities of tangential airflow on laser irradiation. Its influence factors mainly include oxidation reaction promotion, convective heat transfer coefficient increase and aerodynamics. The couple interaction between the factors is analyzed. But the material research of tangential airflow laser irradiation effect is not enough, and the analysis of fracture before melting is not clear, which need further research for improvements.
