DEVELOPMENT OF TECHNOLOGY AND EQUIPMENT FOR PRESS WELDING OF TUBULAR PARTS UNDER THE CONDITIONS OF PRODUCTION FOR THE PURPOSE OF SAVING RESOURCES AND INCREASE IN THE REALIABILITY OF HIGHLOADED PRODUCTS

摘要

Replacement of outdated technologies in the production of tubular parts is an urgent task. The paper presents the materials of carried out investigations on press welding of high-load steel tubular parts with a diameter of up to 120 mm with a wall thickness of up to 6 mm, development of control system, metallographic and mechanical examinations on determination of the properties of welded joints. The main technological advantages of press welding of high-loaded products are shown.
