随着激光热源额定功率持续增长，高达万瓦级的激光焊接技术已在国内外成为焊接领域的热点。系统性地阐述了国内外万瓦级激光焊接技术的研究现状、发展趋势以及存在的问题，包括激光自熔焊、真空激光焊、激光-电弧复合焊和激光-埋弧耦合焊，主要涉及焊缝成形、熔池行为特征、羽辉物理特性、焊接缺陷的抑制。研究发现，万瓦级激光焊接具有显著优势，包括高焊接速度、低热影响区、实现深宽比更优的焊接效果和高效率焊接，但也存在工艺窗口窄、易产生飞溅等挑战。真空激光焊接能够显著增加焊缝熔深，提高焊缝质量，激光-电弧复合焊具有高效、适应性强等特点，而激光-埋弧耦合焊接仍处于起步阶段，需要进一步研究。
As a typical representative of current high-efficiency and high-quality welding methods
laser welding technology has been utilized in various fields with technical advantages such as high stability and low deformation. With the continuous improvement of the rated power of the laser heat source
10 000-watt high-power laser welding has become a popular international cutting-edge welding technology. Utilizing the ultra-high power density of 10 000-watt laser
the welded seam with greater depth-to-width ratio characteristics can be obtained. Under the same plate thickness conditions
the use of 10 000-watt laser welding can reduce the number of layers of weld passes
thus reducing the number of interlayer cleanup and reducing the number of unnecessary beveling
etc.
which can greatly improve the welding efficiency. The paper summarizes and analyzes the domestic and international research status
development trend and problems of 10 000-watt laser self-melting welding
10 000-watt vacuum laser welding
10 000-watt laser-arc hybrid welding and 10 000-watt laser submerged arc coupling welding. It mainly involves weld shaping
molten pool behavior characteristics
physical properties of plume glow
and inhibition of welding defects.
