    • Abstract:
      Oil and gas pipelines, marine application, offshore structures are subjected to aggressive environment which causes corrosion and fatigue in some parts of them. Thus, they need to repair as soon as possible. Underwater welding is used for that purpose which is suitable for urgent repairs. Both types of underwater welding (wet and dry) suffer from many Risks and difficulties that affect the life of welder, on the other hand, reduce the mechanical properties of welds. In this article, the challenges associated with the underwater welding process and methods of treating them or minimizing their effects are reviewed. [ABSTRACT FROM AUTHOR]
    • Abstract:
      تتعرض خطوط أنابيب النفط والغاز والتطبيقات البحرية والهياكل البحرية لبيئة عدوانية تسبب التآكل والإرهاق في بعض أجزاء منها. وبالتالي ، يحتاجون إلى الإصلاح في أسرع وقت ممكن. يستخدم اللحام تحت الماء لهذا الغرض وهو مناسب للإصلاحات العاجلة. يعاني كلا النوعين من اللحام تحت الماء (الرطب والجاف) من العديد من المخاطر والصعوبات التي تؤثر على عمر اللحام ، من ناحية أخرى ، تقلل الخواص الميكانيكية للحامات. في هذه المقالة ، تتم مراجعة التحديات المرتبطة بعملية اللحام تحت الماء وطرق معالجتها أو تقليل آثارها.
