The invention provides a side wall welding method and device, a side wall, a vehicle body and a rail vehicle. The side wall welding method comprises the steps of pressing a cross beam on the surface of a side wallboard; and conducting spot welding on the cross beam at intervals through laser beams in the length direction of the cross beam, so that the cross beam is welded to the surface of the wallboard through a plurality of spot welding points. According to the side wall welding method, laser single-face spot welding is used for achieving welding and fixing of the cross beam on the wallboard, namely, the plurality of spot welding points formed on the cross beam are used for replacing a full-length welding seam formed in existing cross beam welding, so that the problem of local welding defects caused by a middle area of the full-length welding seam is completely avoided, and on the basis of ensuring the welding strength of the cross beam, the welding quality between the cross beam and the wallboard is effectively improved.

    本发明提供一种侧墙焊接方法及装置、侧墙、车体、轨道车辆。该侧墙焊接方法包括:将横梁压紧于侧墙墙板的表面;沿横梁的长度方向利用激光束对横梁间隔点焊,以通过若干个点焊的焊点将横梁焊接于墙板的表面。该侧墙焊接方法利用激光单面点焊实现横梁在墙板上的焊接固定,即以横梁上形成的若干个点焊焊点替代现有的横梁焊接中形成的通长焊缝,从而完全避免由通长焊缝的中间区域引起的局部焊接缺陷问题,进而在保证横梁的焊接强度的基础上,有效提高横梁与墙板之间的焊接质量。
