The Senior Welding Engineer leads the development, qualification, and oversight of welding procedures and fabrication standards across complex marine structures and piping systems. This position provides expert guidance on TIG, MIG, and Stick (SMAW) welding applications for a wide range of marine-grade materials. The engineer ensures that welding activities meet performance, safety, and regulatory requirements while supporting production efficiency, defect reduction, and compliance with classification society rules and international standards.
Develop and oversee Welding Procedure Specifications (WPS), Procedure Qualification Records (PQR), and Welder Performance Qualifications (WPQ) for structural, piping, and pressure-retaining components in shipbuilding and offshore fabrication.
Lead the selection and qualification of welding consumables and materials for carbon steel, stainless steel, Cu-Ni, duplex, aluminum, and other marine alloys.
Provide expert technical support to resolve complex welding issues such as porosity, cracking, lack of fusion, and distortion during production.
Define and monitor heat input control, preheat/post-weld heat treatment (PWHT), interpass temperature limits, and weld sequencing strategies.
Support and approve welding-related documentation for compliance with ASME Section IX, AWS D1.1/D1.2, ISO 15614, API 1104, and classification standards from ABS, DNV, BV, LR, NAVSEA, or MIL-STD.
Review design drawings and fabrication plans to verify weldability, joint design, and accessibility.
Interface with QA/QC teams for review of NDT reports (RT, UT, VT, MT), weld defect assessments, and repair procedures.
Serve as technical liaison with clients, classification societies, and third-party inspectors for welding audits, inspections, and approvals.
Lead internal audits of welding practices, consumable storage, welder logs, and procedure adherence in workshops and shipboard locations.
Mentor and train welding engineers, inspectors, and production staff on best practices, new materials, welding codes, and innovation in welding technologies.
Bachelor’s or Master’s degree in Welding Engineering, Mechanical Engineering, Metallurgical Engineering, or Materials Science.
8–15 years of experience in welding engineering within marine, offshore, defense, or shipbuilding environments.
Deep technical knowledge of TIG, MIG, SMAW, and advanced processes (GTAW, FCAW, SAW) as applied to marine fabrication.
Proficient in weld metallurgy, distortion control, defect analysis, and welding-related FEA/stress considerations.
Strong understanding of international welding codes, NDT requirements, and fabrication tolerances.
Proven experience in interacting with certifying bodies (e.g., ABS, DNV, NAVSEA) and managing inspections and audits.
Certified Welding Inspector (CWI), International Welding Engineer (IWE), or CSWIP 3.2 certification.
Experience with automated and robotic welding systems in modular or high-volume marine production.
Familiarity with digital welding traceability systems, WPS management tools, and weld quality databases.
Exposure to specialized welding environments (underwater, cryogenic LNG systems, or pressure boundaries).
Based in fabrication yards, shipyards, or project engineering offices with frequent site visits and field inspections.
PPE and strict adherence to HSE practices required.
May involve extended hours or night/weekend work during production surges, audits, or commissioning.
Travel to offshore sites, supplier workshops, or client yards may be required.
