摘要
Coiled tubing with higher strength and larger diameter is widely used in oil and gas engineering. Local damage generated during its working operation will decrease the fatigue life and strength, but replacement will introduce with extra cost. In order to repair the damaged part with lower cost or obtain longer coiled tubing, tube to tube butt TIG welding is adopted. This paper described characteristics of field butt welding and summarized welding sequence. Groove type and preparing, type and diameter of welding wire, welding position, type and flow rate of shielding gas and diameter of welding electrode are all determined. Grain refinement measurements, heat input and welding thermal cycle control method are specified. The welding process has excellent repeatability, the soundness and integrity of weld joint can be guaranteed. The experiment results showed that lower heat input and multi-layer welding can increase fatigue life of welded joint.
