About this book:

This comprehensive guide explores the sophisticated engineering and practical execution required for welding and fabrication in the modern shipbuilding industry. Moving from the historical transition from riveting to fusion welding, the text provides a detailed technical overview of how massive steel structures are transformed into seaworthy vessels. It bridges the gap between workshop realities and the rigorous standards of international classification societies, covering essential welding processes such as SMAW, GMAW, FCAW, and SAW, as well as the specialized materials—including high-strength steels, aluminum, and corrosion-resistant alloys—that form the backbone of marine hulls and outfitting.

The book serves as a vital reference for managing the unique challenges of the shipyard environment, specifically focusing on joint design, precise fit-up, and the complex mechanisms of welding distortion. Readers will find in-depth strategies for controlling thermal expansion, implementing effective welding sequences, and utilizing both manual and automated robotic systems. Beyond the arc, the guide emphasizes the critical importance of quality management, detailed non-destructive testing (NDT) methods like Phased Array UT, and the stringent safety protocols required for hot work and confined space operations.

Designed for welding engineers, supervisors, and quality inspectors, this reference provides actionable insights into troubleshooting defects through root cause analysis and maintaining rigorous traceability. It further addresses the long-term durability of vessels by exploring post-weld heat treatments, thermal straightening, and the essential interfaces between fabrication and corrosion protection systems. Whether qualifying a new procedure or overseeing block erection, this book offers the procedural backbone necessary to ensure structural integrity and operational safety in the demanding marine environment.

What You'll Find Inside:

• Comprehensive guide to marine welding processes including SMAW, GMAW, FCAW, SAW, and GTAW, with specific criteria for process selection based on material thickness and joint design.
• Detailed exploration of classification society codes (IACS, ABS, DNV, LR) and the essential role of Welding Procedure Specifications (WPS) and Procedure Qualification Records (PQR).
• Practical strategies for managing welding distortion in large ship blocks through sequencing, pre-setting, fixturing, and thermal straightening techniques.
• In-depth analysis of non-destructive testing (NDT) methods such as Phased Array Ultrasonic Testing (PAUT), radiography, and magnetic particle inspection tailored for marine structures.
• Technical breakdown of specialty welding applications including marine piping systems, dissimilar metal joints, and the integration of automation and hybrid laser-arc technology.

Who's It For:

This book is specifically designed for welding engineers, shipyard supervisors, and quality control inspectors involved in marine fabrication. It also serves as an essential reference for naval architects and classification society surveyors who require a deep understanding of the procedural and safety standards governing ship construction. Additionally, it provides valuable technical insights for advanced welders looking to specialize in high-stakes marine environments.
