对低合金高强度钢焊接结构中出现的冷裂纹研究,一直是焊接领域中颇受关注的课题之一。在评定材料冷裂敏感性的各种试验方法中,插销法是一种简便易行、材料节省的评定试验,其结果可进行定量比较。本文从深入分析一种低合金高强度钢(σ_3=60公斤/毫米~2)由摇
Research on the cold crack in low-alloy high-strength steel welded structure has been one of the most concerned issues in the field of welding. Among the various test methods for assessing the cold crack susceptibility of materials, the latch method is an easy and material-saving evaluation test that can be compared quantitatively. In this paper, an in-depth analysis of a low-alloy high-strength steel (σ_3 = 60 kg / mm ~ 2)
