摘　　要：极地重载甲板运输船的甲板区域的纵骨与壁板的材质为EH36,厚度较厚,在生产过程中出现立角焊的纵向裂纹。作者针对本船的该类裂纹进行检验和分析,并进行相关试验,通过分析得出角焊间隙、焊接参数、摆动宽度对于焊缝的力学性能有重要影响。The main structure material of longitudinal bars and frames in the polar class heavy transport deck carrier is of grade EH36 with the thickness much more than the normal vessel. The longitudinal cracks were found in the vertical fillet welds on the site. This paper makes tests for this problem, analyses the result and concludes that the gap of T joints, parameters and the range of the width will affect the result of mechanics capability.

关 键 词：极地重载甲板运输船 立角焊 纵向裂纹
