321-Q370q复合板焊接冷裂纹敏感性试验研究

Experimental Investigation on Cold Crack Sensibility of 321-Q370q Clad Plates

    摘要
  • 摘要: Q370q钢是武汉钢铁公司和中铁大桥工程局共同研究开发的新型桥梁用钢。为了达到永久性防腐蚀的目的,采用爆炸焊接法制成321-Q370q复合板。本文研究了321-Q370q复合板焊接冷裂纹敏感性,试验结果表明:321-Q370q复合板具有优良的抗裂性能。

     

    Abstract: Q370q steel is a new type bridge steel which is codeveloped by WUHAN IRON AND STEEL GROUP CORP and CHINA ZHONGTIE MAJOR BRIDGE ENGINEERING GROUP CORP.In order to realize corrosion prevention once for all,321-q370q clad plates was fabricated by means of explosive welding.Reseach on 321-q370q clad plates welding cold cracking sensitivity was carried out,and the results show that 321-q370q plates have excellent anti-cracking performance.
