Welding the Split-Line of GT Wrapper Casing


Thread Starter


Hi all,

Recently, we had an issue of hot air leak at the split-line (near to combustion can area) after commissioning from bearing inspection outage. As discussed with established GT repairer, we carried out plate welding at split-line of GT wrapper casing to prevent hot air leaks inside turbine compartment. May i know the effect on the GT operation/casing expansion?
