摘要
激光-电弧复合焊技术是一种具有较好工业应用前景的新技术,目前已经引起了国内外研究人员的重视。激光-电弧复合焊接将两种物理性质和能量传输机制截然不同的热源复合在一起,实现优势互补,提高焊接效率和质量。结合作者的研究工作,概括了激光-电弧复合焊接中激光与电弧相互作用、熔滴过渡特性、小孔和熔池动态行为、复合焊接工艺技术及应用等方面的最新研究进展。
Laser-arc hybrid welding is a promising technology which can be widely used in industry and it attracts attention of the researchers worldwide. Combining two heat sources with different physical properties and energy transmission mechanisms together, laser-arc hybrid welding possesses the composite advantages of laser welding and arc welding. Some aspects on laser-arc hybrid welding such as the laser-arc interaction, droplet transfer characteristics, dynamic behaviors of the keyhole and the weld pool, hybrid welding processes and their applications are reviewed.
