The invention belongs to the technical field of railway vehicles, and relates to a railway vehicle laser welding stainless steel side wall structure which comprises a side wall plate and a side wall framework, and the side wall framework comprises a stand column, a side wall upper edge beam and a side wall lower edge beam; the side wall lower edge beam is a B-shaped beam, the upper end of the stand column is in arc welding connection with the side wall upper edge beam, the lower end of the stand column is in arc welding connection with the upper wing face of the side wall lower edge beam, a corrugated plate is further arranged between the side wall plate and the side wall framework, and the corrugated plate is fixed between the stand column and the side wall plate. The side wall plate, the side wall upper edge beam and the corrugated plate are intermittently welded through laser welding, and the lower wing face of the side wall plate is opposite to the lower wing face of the side wall lower edge beam. According to the side wall structure, the corrugated plate is used for replacing a traditional reinforcing beam structure and a cross beam structure, the side wall plate and the corrugated plate are connected through laser welding, the corrugated plate and the side wall framework are connected through laser welding, welding deformation of the side wall structure can be reduced, the flatness of the outer surface of the side wall can be improved, and the overall appearance quality of a vehicle can be improved.
本发明属于轨道车辆技术领域,涉及一种轨道车辆激光焊不锈钢侧墙结构,该侧墙结构包括侧墙板、侧墙骨架,侧墙骨架包括立柱、侧墙上边梁、侧墙下边梁;所述侧墙下边梁为乙型梁,所述立柱的上端与侧墙上边梁弧焊连接,立柱的下端与侧墙下边梁的上翼面弧焊连接,所述侧墙板与侧墙骨架之间还设置有波纹板,所述波纹板固定在立柱与侧墙板中间,所述侧墙板与侧墙上边梁、波纹板采用激光焊断续焊接,侧墙板与侧墙下边梁的下翼面相对设置。该侧墙结构使用波纹板替代传统补强梁结构及横梁结构,侧墙板与波纹板、波纹板与侧墙骨架均是采用激光焊连接,不仅可以减少侧墙结构焊接变形,改善侧墙外表面平面度,还能提高车辆整体外观质量。
