激光焊接在传递能量方面提供了巨大的灵活性。然而，它确实需要监控大量参数和现象，以便控制过程并确保高质量的处理。在激光焊接中，可以使用不同的参数组合（例如激光功率、行进速度）来实现相同的熔深深度。由于光束直径的影响，问题变得更加复杂，不同激光系统之间的光束直径可能会有很大差异。在这项工作中，提出了一个经验模型，该模型能够实现与光束直径无关的特定穿透深度。首先，用户选择满足一定质量要求和必须适应的熔深深度的焊缝形状，然后模型将指定如何使用具有特定光束直径的特定激光系统来实现该焊缝。 (C) 2013 Elsevier Ltd. 保留所有权利。
Laser welding offers enormous flexibility in terms of delivered energy. It does however, require a vast amount of parameters and phenomena to be monitored in order to control the process and to ensure high quality processing. In laser welding the same depth of penetration can be achieved using different combinations of parameters, such as laser power, travel speed. The problem is further complicated by the effect of beam diameter, which may vary significantly between different laser systems. In this work an empirical model, which enables achievement of a particular depth of penetration independent of the beam diameter is presented. First, the user selects a weld shape which meets a certain quality requirements and depth of penetration that have to be accommodated and then the model will specify how to achieve this weld using a particular laser system with a particular beam diameter.
