| Abstract: | The cracking place of 650 mm roller was analyzed, and the reasons of shaping crackle in the roller was found out. By means of adopting preheating before welding, low hydrogen welding and heat treatment after welding and some other steps, the built-up welding repairing of the crackle in 650 mm roller tip end was successfully achieved. At the same time, the service cycle of roller was prolonged. |
