| Abstract: | Welding repair onto in-service pressure pipelines has good economic efficiency and application trend, because it is much quick and has little effect to normal run of pipeline. But it is also very dangerous because burn-through might happen during welding. The thesis summarizes the sense of the research of buru-through during in-service welding, and analyses the effect of pipe thickness, pressure, and heat input which are related to buru-through. It summarizes the achievements and disadvantages of burn-through research home and abroad. Finally, the development prospect of burn-through during in-service welding is pointed out. |
