激光焊接技术起始于20世纪70年代的美国。随着激光器本身的发展,即功率由小到大、光束质量及稳定性的提高,以及各种新型激光器的出现,激光焊接技术已在工业发达国家普遍应用于工业界的各领域,属制造业的共性关键技术。 一、激光焊接技术的主要优点 ($)焊件质量好、变形及 Laser welding technology began in the 1970s in the United States. With the development of the laser itself, that is, the power from small to large, the improvement of beam quality and stability, and the emergence of a variety of new lasers, laser welding technology has been widely used in various industrial fields in the industrialized countries, Common key technology. First, the main advantages of laser welding technology ($) Weld quality, deformation and
