For　the　residual　stress　measurement　of　rolling　aluminum　alloy　using　X-ray,　the　number　of　diffraction　planes　in　different　ψ　angular　positions　is　different　due　to　the　preferential　orientation.　The　results　in　the　diffraction　intensity　were　different　at　different　ψ　angular　positions.　Consequently,　the　determination　of　peak　position　of　θ-2θ　is　affected　and　the　2θ-sin2ψ　and　Ip-sin2ψ　appear　vibration　with　different　degrees.　As　a　result,　the　accuracy　of　the　measure　results　is　decreased.　In　this　paper,　the　variation　of　different　diffraction　planes　with　the　intensity　distribution　of　ψ　angular　position　are　analyzed　by　using　the　＇multiply　planes　measure　method＇.　The　results　show　that　the　diffraction　peak　intensity　and　the　intensity　ratio　can　be　ensured　by　using　the　＇multiply　planes　measure　method＇.　The　measurement　results　are　in　good　agreement　with　the　theoretical　results,　which　meet　the　requirement　of　rolling　aluminum　measurement.　©　2017,　Editorial　Board　of　Transactions　of　the　China　Welding　Institution,　Magazine　Agency　Welding.　All　right　reserved.
