| Abstract: | The material of the high inter case of the turbine is the heatproof steel.Because the capability of welding is not fine,the tendency of the cold crack,hot crack and re hot crack is greater.In order to avoid the cracks,the proper welding technology and method are adopted in welding.According to the different status,the different welding technology and method are applied in repair welding,so the quality of the repair welding is ensured. |
