海洋工程中常见焊接缺陷的成因探讨及对策

海洋工程钢结构制造过程中焊接接头、焊缝和热影响区是最容易产生各种缺陷的地方.缺陷,顾名思义是一种欠缺、不足、不完善的地方,也包括物体的损伤.焊接缺陷可定义为不完善焊接施工所导致的工件使用性能的不连续性；也可定义为由于原有或积累的影响,使部件或产品不能满足最低验收标准或规程的一种或多种不连续焊接缺陷的研究是伴随着焊缝质量检测方法的进步而发展的]；故对焊接缺陷及其缺陷对焊接构件承载力的影响程度的研究是很有必要的.该文以外观检测方式、用PL19-3项目中出现的焊接缺陷,探求钢结构焊接缺陷类型、特点及其产生缺陷的成因；并通过具体的案例进行分析,从而达到减少缺陷产生及保证工程质量的目的.

Influence of Common Defects to Welding Quality

Welded joints,weld and heat affecting zone in steel manufacturing process is the place most probably to produce various defects.Defect is known as a lack,deficiency or imperfections,where defect or damage may occur.Welding defects can be defined as the discontinuity of mechanical performance caused by welding construction.It also can be defined as the accumulation of defects or causing parts or products failure to meet the minimum acceptance standard or regulation.Visual inspection approach is applied to we...
