Limit　loads　are　widely　studied　and　several　limit　load　solutions　are　proposed　to　some　typical　geometry　of　weldments.　However,　there　are　no　limit　load　solutions　exist　for　the　single　edge　crack　weldments　in　tension　(SEC(T)),　which　is　also　a　typical　geometry　in　fracture　analysis.　The　mis-matching　limit　load　for　thick　plate　with　SEC(T)　are　investigated　and　the　special　limit　load　solutions　are　proposed　based　on　the　available　mis-matching　limit　load　solutions　and　systematic　finite　element　analyses.　The　real　weld　configurations　are　simplified　as　a　strip,　and　different　weld　strength　mis-matching　ratio　M,　crack　depth/width　ratio　a/W　and　weld　width　2H　are　in　consideration.　As　a　result,　it　is　found　that　there　exists　excellent　agreement　between　the　limit　load　solutions　and　the　FE　results　for　almost　all　the　mis-matching　ration　M,　a/W　and　ligament-to-weld　width　ratio　(W-a)/H.　Moreover,　useful　recommendations　are　given　for　evaluating　the　limit　loads　of　the　EBW　structure　with　SEC(T).　For　the　EBW　joints　with　SEC(T),　the　mis-matching　limit　loads　can　be　obtained　assuming　that　the　components　are　wholly　made　of　base　metal,　when　M　changing　from　1.6　to　0.6.　When　M　decreasing　to　0.4,　the　mis-matching　limit　loads　can　be　obtained　assuming　that　the　components　are　wholly　made　of　base　metal　only　for　large　value　of　(W-a)/H.　The　recommendations　may　be　useful　for　evaluating　the　limit　loads　of　the　EBW　structures　with　SEC(T).　The　engineering　simplifications　are　given　for　assessing　the　limit　loads　of　electron　beam　welded　structure　with　SEC(T).
