奥氏体不锈钢应变强化压力容器能满足节约能源降低成本的需求,其应用前景广泛。本文分别研究了不同应变量、相同应变量不同应变强化拉伸方向及不同焊接方法对应变强化奥氏体不锈钢焊缝中未焊透缺陷的影响。所得实验结果对产品生产及相关标准的制定具有一定的借鉴意义。 Austenitic stainless steel strain hardening pressure vessels can meet the energy saving needs of reducing costs, its wide range of applications. In this paper, the effects of different strain amount and different strain amount on strain-hardening tensile direction and different welding methods on the weld-less imperfections in austenite stainless steel weld were studied. The experimental results obtained for the production of products and related standards have some reference significance.
