The current situation of coring drill pipe and friction welding technology is presented.Through the comparison of 3 kinds of deep hole wire-line coring drill pipe connection structure and production process, analysis was made on the ad-vantages of the use of thin-wall wire-line coring drill pipe by friction welding in deep hole drilling.The paper introduces the structure design and the machining process of ?73mm ×5mm thin-wall wire-line coring drill pipe by friction welding and puts forward the main technical problems and matters needing attention in the welding process.The main technical parame-ters of the drill pipe are obtained through the tension and torque tests, the maximum tensile force and torque are 580kN and 5500N· m respectively, and the recommended use depth is 2000~3000m.
