摘要

对锁眼行为的理解一直是一个非常重要的话题，许多问题仍然值得关注。我们分析了在一个非常简单的配置的情况下，我们已经使用了全渗透激光焊接条件下的锁孔动力学。我们将展示这些焊接配置的研究结果，其中实验使用了4kw Nd:YAG激光器，其特点是光斑直径为0.4 mm，强度分布为“顶帽”

Study of keyhole geometry for full penetration Nd-Yag CW laser welding

The understanding of keyhole behavior is always a topic of great importance where many questions are still of concern. We have analyzed the keyhole dynamics in the case of a very simple configuration where we have used full penetration laser welding conditions. We will present the results of the study of these welding configurations, where experimentally a 4 kW Nd:YAG laser has been used, characterized with a 0.4 mm spot diameter and a "top-hat" intensity distribution
