- 論文の詳細を見る
Laser beam welding using two or twin laser beams has become an emerging welding technique. In addition to the experimental researches, the numerical modeling is helpful to reveal invisible flow phenomena in welding process and provide possible improvements to the welding technique. This paper proposed a two-dimensional thermal-fluid coupled model and the suitable boundary conditions for analyzing the flow behavior of molten pool. Using finite element analysis software MSC. Marc, the flow pattern and shape of molten pool for the single and twin beam welding were systematically investigated. The obtained numerical results could be successfully used to explain the experiment results.
