在冷却速度较快的焊接过程中，根据凝固方式和镍、铬当量，考虑了奥氏体不锈钢焊缝中的凝固裂纹。以CREQ/NIEQ(焊接研究理事会)比值1.6作为最终焊缝金属避免热裂纹的标准，提出了一种选择填充物或缓冲材料当量的方法。
Solidification cracking in austenitic stainless steel welds has been considered based on the solidification modes and the nickel and chromium equivalents in welding processes where the cooling rates are high. Taking a Creq/Nieq (Welding Research Council) ratio of 1.6 as a criterion for the final weld metal to avoid hot cracking, a methodology is proposed for the selection of filler or buffer material equivalents.
