The invention relates to a manufacturing method of an end wall of containers, including the following steps: a corner post, an upper beam and a lower beam are welded to form an end wall frame; two or more than two group plates forming an end wall plate are welded and connected together by a technology plate to form a blank plate of the end wall; a clearance is reserved between the group plates; the blank plate of the end wall is welded inside the end wall frame; then the group plates on the blank plate of the end wall are welded at the clearance between the group plates by dual-surface welding. Since welding of the group plates of the end wall is carried out after the blank plate of the end wall is welded on the end wall frame, the clearance between the group plates on the blank plate of the end wall generates welding shrinkage, thus removing the wave deformation generated by welding the blank plate of the end wall on the end wall frame, thus effectively controlling the welding deformation of the end wall plate, decreasing the internal stress on the end wall plate, remarkably increasing the strength, and requiring no other auxiliary facilities during the work implementation.
