摘要

针对海上超厚板高强度钢焊接结构开裂的现象，通过综合原因排查分析、开裂位置全面探伤检测、断裂部位取样及实验室检测分析等手段，进行了结构开裂原因分析。根据结构的具体工况科学采用了ACFM和PAUT先进无损探伤技术，精准确定了裂纹相关信息；通过断裂结构的断口分析、化学成分分析、金相检测及硬度检测，确定了结构断裂的失效模式为焊接构件焊缝焊趾处发生了延迟冷裂纹。海上超厚板高强度钢开裂原因分析为后续产品返修及类似产品的高质量生产制造提供了宝贵技术经验。

Abstract

According to the phenomenon of cracking of welded structure of ultra-thick plate high-strength steel at sea, the causes of cracking were analyzed by means of comprehensive cause investigation and analysis, comprehensive crack location detection, fracture site sampling and laboratory detection. According to the specific working conditions of the structure, the advanced non-destructive testing technology of ACFM and PAUT is scientifically adopted to accurately determine the crack related information. Through fracture analysis, chemical composition analysis, metallographic detection and hardness detection, it is determined that the failure mode of the structural fracture is delayed cold crack at the weld toe of the welded member. The analysis of cracking causes of offshore ultra-thick plate high-strength steel in this paper provides valuable technical experience for subsequent product repair and high-quality manufacturing of similar products.
