不同焊接工艺对镍基合金焊丝焊缝金属抗拉强度的影响

Effect of different welding process on tensile strength of weld metal of nickel base alloy welding wire

本文针对核岛主设备用INCONEL 690镍基合金焊丝,通过焊接工艺试验,获得了不同焊接工艺对INCONEL 690焊丝焊缝金属抗拉强度的影响规律,同时获得了焊后消应力热处理对其的影响规律。

Here refers to the nickel-based alloy welding wire INCONEL 690 in the nuclear main equipment application,obtained the influence rules of tensile strength of nickel-based alloy welding wire weld metal under different welding process,as well as the influence rules of post weld stress-stress heat treatment is obtained.
