摘要

本文的目的是建立数学模型和相关的数值技术来计算熔池中的瞬态传热和流体流动，并了解导致双光束激光焊接过程中熔池椭圆形的机制。通过组合多个Nd:Yag激光器，可以增加总输出功率以实现深穿透。

Modeling the transport phenomena during dual beam laser welding process

The objective of this paper is to establish mathematical models and the associated numerical techniques to calculate the transient heat transfer and fluid flow in the melt pool, and to understand the mechanisms leading to the oval shape of the melt pool during dual beam laser welding. By combining several Nd:Yag lasers one can increase the total output power to achieve deep penetration.
