weld failure
解釋
焊縫開裂-
The effect of girth weld strength match on the limit load and fracture resistance of high - grade, large diameter pipelines was analyzed with failure analysis diagram ( fad ) method
摘要採用失效評定圖技術分析了油氣長輸管道特別是高強度大口徑管道環焊縫不同強度匹配形式對管道極限承載能力以及抗斷性能的影響。 -
Effect of girth weld strength match on limit load and fracture resistance of high strength, large diameter pipelines steel is analyzed with fad ( failure analysis diagram ) method
摘要採用失效評定圖技術分析了油氣長輸管道中高強度管?鋼大口徑管道環焊縫不同強度匹配形式對管道極度限承載能力以及抗斷性能的影響。 -
The results show that : the strength and fatigue lifetime of the outer casing including welding line can satisfy the design requirement. although the some parts of bearing has been yielded, the strength at the weld is large enough for requirement. and welding defect, indicted by sem analyses of failure section, is main reason affecting fatigue lifetime
分析結果表明：外機匣（包含焊縫）強度和壽命滿足設計強度和壽命的要求；軸承座的強度已經進入屈服階段，而軸承座及其焊縫處的壽命卻是滿足設計壽命要求；另外斷口的金相分析表明焊接缺陷的存在是影響疲勞壽命的主要原因之一，故需提高焊接技術，減少焊接缺陷的存在以提高焊接結構的壽命。
