摘要:

利用ANSYS 对低活化铁素体马氏体(RAFM)钢进行非熔化极气体保护焊(TIG 焊)与电子束焊的抗疲劳模拟分析,再利用SDS200 电液伺服疲劳试验机对TIG 焊和电子束焊的两种RAFM 钢试件进行实验。通过施加相同梯度负荷对TIG 焊和电子束焊试件进行焊缝的疲劳性能实验。与实验结果对比分析,结果显示电子束焊优于 TIG 焊,但在一定负载下可以用TIG 焊代替电子束焊。

Abstract:

The anti-fatigue simulation of Tungsten Inert Gas (TIG) welding and electron beam welding of reduced activation ferrite martensite (RAFM) steel was carried out by using ANSYS. Two types of RAFM steel specimens of TIG welding joint and electron beam welding joint were also tested by SDS200 electro-hydraulic servo fatigue testing machine. The fatigue performance of the weld joint both on TIG welding and electron beam welding was tested by applying the same gradient load. Comparison with experimental results shows that electron beam welding is superior to TIG welding, but under certain load, TIG welding can be used instead of electron beam welding.
