The pressure of media flowing in the pipe is one of the most important factors that has greatly influence on burn-through during in-service welding. The burn-through phenomenon was studied on the radial displacement with numerical simulation method supplemented by means of actual wielding tests under different inner pressure. The results show that the radial displacement of the node beneath the molten pool increases with the increasing temperature of welding. When the temperature is close to the peak temperature, the deformation of the node has a mutation. Futhermore, the mutation degree becomes larger with higher inner pressure. Under a specific temperature field, the radial displacement of the node with maximum temperature at the inner wall changes linearly with the increasing pressure at the first stage, but when the inner pressure is up to a fixed value, the trend cannot be continued, and a mutation appears and indicts that the burn-through should occur if we don’t take preventive measures. So the radial displacement can be seen as the burn-through criterion of in-service welding.

The pressure of media flowing in the pipe is one of the most important factors that has greatly influence on burn-through during in-service welding. The burn-through phenomenon was studied on the radial displacement with numerical simulation method supplemented by means of actual wielding tests under different inner pressure. The results show that the radial displacement of the node beneath the molten pool increases with the increasing temperature of welding. When the temperature is close to the peak temperature, the deformation of the node has a mutation. Futhermore, the mutation degree becomes larger with higher inner pressure. Under a specific temperature field, the radial displacement of the node with maximum temperature at the inner wall changes linearly with the increasing pressure at the first stage, but when the inner pressure is up to a fixed value, the trend cannot be continued, and a mutation appears and indicts that the burn-through should occur if we don’t take preventive measures. So the radial displacement can be seen as the burn-through criterion of in-service welding.
