摘要
系统地总结了低合金相变诱发塑性(TRIP)钢激光焊接的最新研究成果。重点介绍了在激光条件下TRIP钢焊缝中气孔的形成、熔化区的凝固过程、熔化区和热影响区的组织和性能。还介绍了TRIP钢与异种钢板的激光拼焊,TRIP钢的激光切割、激光钎焊和激光点焊。指出了今后TRIP钢激光焊接的研究方向。
Recent achievements in laser welding of transformation induced plasticity （TRIP）-assisted steel were systematically summarized. In the laser welding process of TRIP-assisted steel, the formation of porosities in the weld bead, solidifying procedure of fusion zone （ FZ）, microstructure and properties of FZ and heat affected zone （HAZ） were emphatically described. Laser welding tailored blanks of TRIP-assisted steel with dissimilar materials, and laser cutting, laser brazing, laser spot welding of TRIP-assisted steel were also introduced. Future directions in research of laser welding of TRIP-assisted steels were pointed out.
