摘要：

Ti60　titanium　alloy　plates　were　welded　by　electron　beam,　and　the　welding　residual　stress　was　tested　and　simulated　by　the　residual　stress　tester　and　finite　element　analysis.　The　comparison　of　the　residual　stress　values　caused　in　the　three　kinds　of　welding　processes　of　pre-heating,　slow　cooling　and　both　pre-heating　and　slow　cooling　was　carried　out.　The　residual　stress　distribution　law　was　also　studied.　Results　show　that　in　the　vertical　welding　section,　the　longitudinal　welding　residual　stress　tested　is　similar　to　that　simulated　as　to　the　change　trend;　in　the　parallel　welding　section,　the　distributions　of　the　tested　and　simulated　longitudinal　welding　residual　stress　are　similar.　These　prove　that　the　finite　element　analysis　is　reasonable　and　reliable.　The　process　of　pre-heating　has　little　influence　on　the　welding　residual　stress,　but　the　slow　cooling　process　can　change　its　distribution.　©　2016,　Editorial　Board　of　Journal　of　Aeronautical　Materials.　All　right　reserved.
