Sustainability of Steel weld joints in Seawater Environment-A Critical Review

Abstract

Seawater environments present a multifaceted challenge for steel weld joints, requiring a nuanced approach to ensure their sustainability. A review of existing literature reveals that various factors influence the long-term performance of these weld joints. Microstructure, environmental conditions and alloy composition play a major role in the sustainability of steel weld. There are several promising ways to mitigate these detrimental effects, including protective coatings, cathodic protection, surface treatment, corrosion-resistant alloys, monitoring and maintenance, and proper material selection. Welding processes, including methods and parameters, affect steel weld joints' sustainability. To design and preserve durable steel weld joints in seawater, it is crucial to recognize the intricate relationship between mechanical properties, microstructural changes, and environmental conditions. Continued research and development are imperative for enhancing the reliability of marine infrastructure.
