Abstract：

The　low　activation　ferritic　/　martensitic　steels　(RAFM)　are　generally　considered　to　be　the　candidate　structural　materials　for　the　first　wall　and　blanket　of　fusion　reactors,　which　service　in　very　harsh　environment.　This　materials　especially　in　it＇s　welding　joints　will　inevitably　produce　various　defects　such　as　irradiation　defects,　surface　embrittlement,　chemical　etching　and　redeposition,　which　seriously　affect　the　service　life　and　safety　of　the　fusion　reactor.　Welding　technology　is　one　of　the　key　technologies　for　RAFM　steel　to　apply　to　engineering.　The　performance　and　present　research　progress　of　RAFM　steel　are　simply　introduced,　welding　methods　of　RAFM　steel　and　its　research　progress　are　reviewed,　and　potential　application　of　the　welding　technology　of　RAFM　steel　is　also　pointed　out,　which　provides　the　basic　data　for　the　welding　structure　of　RAFM　steel　practically　apply　to　the　fusion　demonstration　reactor.　©　2019　Journal　of　Mechanical　Engineering.
