Abstract

The invention discloses an intensive welding method of a giant complex multi-cavity test platform base. The test platform base is formed by welding mounting units, and the mounting units are prefabricated in a factory through steel plates. The welding method comprises the following steps that firstly, welding grooves of the mounting units are pretreated; secondly, the mounting units are pre-assembled into a whole, and mechanical connection between the mounting units is set; thirdly, before welding, the welding joint positions of the mounting units are preheated; fourthly, the mounting units are welded according to a formulated welding process and welding sequence; and fifthly, after welding, welding joints of the mounting units are subjected to postheating treatment. According to the method, pre-welding machining treatment is carried out on welding components, the welding sequence and welding process parameters are determined, matched mechanical connection is adopted in the welding process to jointly guarantee the welding contraction consistency of welding joints of large steel structures, welding deformation is controlled to the minimum, and the base welding precision requirement is met.

Description

technical field [0001] The invention relates to a method for densely welding the base of a giant complex multi-cavity test platform. Background technique [0002] The large-scale test platform is composed of top beams, columns, movable beams and bases. As the foundation of the test platform, the base has a great influence on the entire large-scale test platform. The base of the test platform not only requires high strength and rigidity, but also requires high precision to ensure that other parts of the test platform based on the base meet the installation requirements. The base structure of the large-scale test platform is huge, and the base is fabricated by splicing and welding 9 complex multi-cavity steel structure installation units. The welding volume is large, and the welding process requires high assembly accuracy of the installation units. There will be large residual stress and stress concentration in the weld and its heat-affected zone produced by welding. The exis...
