通过对激光切割取代冲孔和修边模具,车身总装过程中激光焊接取代电阻点焊,以及车身不同部位不同厚度覆盖件的激光焊接的研究,展示了激光制造技术在汽车制造领域中的优势。介绍了激光宽带熔覆技术,与传统粉末冶金烧结工艺相对比,该激光制造短流程工艺不仅能够提高生产率、缩短制造工艺流程,而且能够降低成本、节约能源。 Through the laser cutting instead of punching and trimming molds, the body assembly process of laser welding instead of resistance spot welding, as well as different parts of body parts with different thickness of the laser welding research, demonstrated the laser manufacturing technology in the automotive manufacturing advantage. The laser broadband cladding technology is introduced. Compared with the traditional powder metallurgy sintering process, this laser manufacturing short process can not only improve the productivity and shorten the manufacturing process, but also reduce the cost and save energy.
