Oil drilling drill pipe is made by friction welding of drill pipe body and joints. On the basis of ensuring that the microstructure and mechanical properties of drill pipe body and joint meet the requirements of technical standards, the microstructure and mechanical properties of friction welding weld and heat affected zone become the key to the quality control of drill pipe. The mechanical properties of friction welding weld and heat affected zone are determined by its organization. Therefore, it is of great significance to study the microstructure characteristics of friction welding weld and heat affected zone of drill pipe and its influence on mechanical properties to ensure and improve the quality of drill pipe. Drill pipe friction welding is a kind of solid phase welding. For a long time, people have been interested in melting welding welds and heat.

drill pipeFriction welding is a solid phase welding. For a long time, people have carried out a detailed study on the organization of fusion welding weld and heat affected zone, and have a clear conclusion.drill pipeSystematic studies on the microstructure of friction welding seams and heat-affected zones have been rarely reported.
