Welding ball and rod piece welding method and net rack construction method
The invention discloses a welding method for a welding ball and a rod piece, which comprises the following steps of: connecting: inserting the end part of the rod piece into a mounting hole in the surface of the welding ball, and forming an annular gap between the side wall of the end part of the rod piece and the inner wall of the mounting hole; bottoming: welding one end, close to the center of the mounting hole, of the annular gap to form a bottoming welding seam; filling and welding the residual part in the annular gap to form a filling welding seam; and the surface of the filling weld joint continues to be welded to form a surface weld joint, the surface weld joint protrudes out of the surface of the welding ball and extends in the circumferential direction of the rod piece, the whole surface weld joint is of a conical structure, and the diameter of the surface weld joint is gradually increased in the direction from the center of the welding ball to the surface of the welding ball. In this way, according to the welding method, the welding ball and the rod piece are welded through the bottoming part, the filling part and the cover face, the step-by-step welding method enables the welding stress of the welding part to be smaller, the connecting effect is better, and the quality defects of false penetration and slag inclusion of a welding seam are avoided.
本发明公开一种焊接球与杆件的焊接方法，包括步骤：连接，将杆件的端部插入至焊接球表面的安装孔内，杆件的端部的侧壁与安装孔内壁之间形成环形间隙；打底，将环形间隙靠近安装孔中心的一端进行焊接形成打底焊缝；填充，焊接环形间隙内剩余部分形成填充焊缝；罩面，在填充焊缝表面继续焊接形成罩面焊缝，罩面焊缝凸出于焊接球表面且沿杆件周向延伸，罩面焊缝整体呈锥形结构，且在沿焊接球的中心至表面的方向，罩面焊缝的直径逐渐增大。如此设置，本发明提供的焊接方法通过打底、填充以及罩面三部对焊接球和杆件进行焊接，这样逐步焊接的方法使得焊接部位焊接应力更小，连接效果更好，避免焊缝出现“假透”“夹渣”的质量缺陷。
