This article discusses the use of flash butt welding (FBW) for increased labor productivity in pipeline construction. However, despite its promise, FBW technologies and equipment have limitations in creating defect-free welded joints. The Ishikawa diagram is used to systematize and analyze factors that cause defects, which are then ranked on a Pareto diagram. The main causes of defects are found to be associated with human factors, such as the qualifications of workers, as well as imperfections in machinery and equipment, material deviations, and technology and measurement limitations. A correlation matrix is used to analyze the causes of the decrease in quality and determine that improving methods and means of FBW processes, along with FBW technologies, is the solution. However, a complete computer model of FBW processes has not yet been created due to difficulties in describing energy release and other energy phenomena. A physical and mathematical model is necessary to take into account energy processes in the welding zone.
