铜的激光束焊接,特别是对于相对较大的板厚度和较低的焊接速度,是非常具有挑战性的关键焊接缺陷是很可能发生的。通过降低环境压力,可以大幅提高工艺能力。所谓的真空激光束焊接(LaVa)工艺变型允许在低于2 m/min的焊接速度下高质量地焊接铜,并且由此以相对低的激光功率实现高的熔深。
Laser beam welding of copper, especially for comparatively high plate thicknesses and low welding speeds, is very challenging critical welding defects are very likely to occur. By reducing the ambient pressure, it becomes possible to increase the process capability in a huge amount. The so called laser beam welding in vacuum (LaVa) process variant allows high quality welding of copper at welding speeds below 2 m/min and thereby a high penetration depth with a comparatively low laser power.
