An experimental research on the LB TRC test for cold crack susceptibility of weld metal for high strength steels 高强度钢焊缝金属LB-TRC冷裂缝试验法的研究&对影响试验结果的因素的探讨
There was residual tensile stress along weld in electron beam welding of TiAl/ TiAl. In the middle of the weld the residual stress was higher, so cold cracks were normal to weld. TiAl/TiAl沿焊缝方向均为残余拉应力,在焊道中部达到较高水平,所以冷裂纹均为垂直于焊缝分布。
