Welding quality control in steel structure construction is the key link to ensure the safety, stability and durability of building structure. In this paper, the technical key points, quality control methods, challenges and countermeasures of steel structure welding construction are discussed in depth, aiming at providing theoretical support and practical guidance for improving steel structure welding quality and ensuring building safety. As an important means to connect steel structure components, the quality of steel structure welding directly affects the bearing capacity and stability of the whole structure. In this paper, the basic process and technical requirements of welding construction of steel structure are summarized, including the selection of welding materials, the configuration of welding equipment, and the setting of welding process parameters. Then, the factors affecting welding quality are analyzed in detail, such as welding environment, welding personnel skill level, welding process control, etc., and the corresponding quality control measures are put forward. In terms of quality control, this paper emphasizes the preparation work before welding, such as the inspection of welding materials, the debugging of welding equipment, and the cleaning of welding areas, so as to ensure that the basic conditions of welding construction meet the requirements. At the same time, the requirement of real-time monitoring and recording in welding process is put forward in order to find and correct welding defects in time. In addition, the inspection and evaluation methods, such as appearance inspection and non-destructive testing, are also introduced to ensure that the quality and performance of welded joints meet the design requirements. In view of the common quality problems in welding construction of steel structure, such as welding deformation, welding crack, welding porosity, etc., this paper analyzes the causes, and puts forward the corresponding prevention and solution measures. For example, welding deformation can be reduced by optimizing welding sequence, controlling welding heat input and strengthening welding area protection. Welding cracks and pores can be prevented by selecting suitable welding materials, adjusting welding process parameters and improving the skill level of welding personnel. This paper summarizes the importance and necessity of steel structure welding construction quality control, and points out the direction and focus of future research. With the continuous development of the construction industry and the continuous progress of technology, the quality control of steel structure welding construction will face more challenges and opportunities. Therefore, it is necessary to continuously strengthen technological innovation and personnel training, improve the quality and efficiency of welding construction, and contribute to the sustainable development of the construction industry.
