In this paper, the technological process of welding and testing welds on seamless pipes is considered. The main objective is to compare the various welding and weld testing methods available on the market, with an emphasis on achieving optimal quality of welded joints. The hypothesis of the work is that different welding methods enable different quality levels of welded joints of seamless pipes. This paper focuses on welding methods of seamless pipes and their characteristics, as well as the quality of welded joints. Research objectives include presenting key information about the welding process, detailing the specifics of seamless pipes, and analyzing welding procedures and weld testing. The methodology of the work includes the use of various scientific methods, including the historical method, analysis and synthesis, inductive and deductive methods, and the comparative method. Knowledge was gathered through literature and practical examples, which were analyzed and presented in the paper. The structure of the work includes an overview of the production of seamless pipes, welding technologies and methods, and welding testing technologies and methods. The paper will provide a detailed description of the technology of welding tests on seamless pipes, which will allow a better understanding of the quality and efficiency of different welding methods.
