Friction welding cavity plate with different welding depths
The invention discloses a friction welding cavity plate with unequal welding depths, which solves the problems of fatigue and other damages caused by the fact that an existing cavity plate is sensitive to welding initial defects and stress directions, and is characterized in that at least one of an outer layer panel or an inner layer panel is a curved plate or an inclined flat plate, and any position of the curved plate takes the outer diameter D of a welded pipe as the chord length; if the corresponding chord height is h1, h1 is smaller than or equal to 1/4t; the included angle alpha between the inclined flat plate and the central axis of the welded pipe is not equal to 90 degrees, the outer diameter D of the welded pipe serves as a right-angle side, the connecting line of two intersection points obtained by extending the two ends of the outer diameter D of the welded pipe to the inclined flat plate in the direction of the central axis of the welded pipe serves as a bevel edge, the height of the other right-angle side of the formed right triangle is h2, and h2 is smaller than or equal to 1/4t. A slow curved plate or a small-slope inclined flat plate is adopted to achieve the structure that the welded pipe forms different welding embedding depths in the circumferential direction of the pipe wall, and different resistance modes are formed by setting and adjusting the radial welding depth.
本申请公开了一种不等焊深的摩擦焊空腔板，解决现有空腔板对焊接初始缺陷和受力方向敏感而造成疲劳等破坏等问题，其技术方案要点为外层面板或内层面板至少有一个为曲面板或者为斜平板，曲面板任意处以焊管的外径D为弦长，所对应的弦高为h1，则满足h1≤1/4t；斜平板与焊管的中轴线的夹角α≠90°，以焊管外径D为一条直角边，以焊管外径D两端沿焊管中轴线方向延伸至斜平板上得到的两个交点的连线为斜边，所构成的直角三角形的另一条直角边高度为h2，则满足h2≤1/4t。采用较缓的曲面板或小斜率斜平板达到焊管沿管壁周向形成不同焊接嵌入深度的构造，并通过径向焊深的设置和调整，形成不同的抗力模式。
