Abstract

The research of technological schemes (the sequence of welding and heat treatment operations) influence on the mechanical properties and the structure is carried out. The influence of technological heatings with a 300 hours duration and 650°C temperature on the weld’s structure and mechanical properties is studied. Friction welding parameters and optimal sequence of welding and heat treatment that allow getting the most high mechanical properties are determined.
