The　microtexture　features　of　Nd:YAG　laser　welded　joints　in　5A90　aluminium-lithium　(Al-Li)　alloys　were　examined　using　electron　back　scattered　diffraction　(EBSD).　Microtexture　was　determined　by　means　of　the　grain　orientation　image　maps　(OIM),　pole　figures　(PF),　misorientation　angles　and　orientation　distribution　function　(ODF)　of　the　weld　metal　(WM),　heat　affected　zone　(HAZ)　and　unaffected　base　metal　(BM)　of　the　welded　joint.　The　results　show　that　there　is　a　change　of　microtexture　in　the　WM　and　HAZ　of　the　welded　joint　in　terms　of　the　component　and　intensity　of　the　texture.　The　HAZ　of　the　welded　joint　inherits　the　texture　characteristics　of　the　BM,　whereas　the　welding　heat　input　has　an　important　influence　on　the　component　C　{112}＜　111　＞.　The　WM　of　the　welded　joint　is　composed　of　predominantly　equiaxed　grains　with　a　random　microtexture.
