| Abstract: | The fitting up and welding technology of the trunnion ring of 50t convener in JISCO was introduced which aimed to extend the working life of the trunnion ring by controlling the welding residual deformation.The fitting up standard was met the needs of the working life of trunnion ring by adopting the new fitting up measures,welding procedure and nondestructive testing method to keep the coaxiality error in the controlled range.Welding technologies to prevent welding residual deformation in the trunnion ring including preheat method and parameters, shape and size of the grooves,welding sequence,welding parameters,interpass temperatures and post weld heat treatment process were intro- duced. |

| Keywords: | converter trunnion ring coaxiality welding deformation working life |
