【Abstract】 The main pipeline of nuclear power has the characteristics of thick pipe wall, narrow welding space on site, and high service environment. Its welding technology has always been one of the hot research directions in the development of nuclear power. This paper introduces the classification of welding methods, summarizes the shortcomings of traditional welding methods, and analyzes the foreign and domestic research status of narrow gap laser hot wire welding. By analyzing the technical advantages and disadvantages of narrow gap laser hot wire welding, the development direction of narrow gap laser hot wire welding in the field of nuclear pipeline welding is proposed, and contributes to the development of nuclear power.更多还原
