Engineering Aspects of Welding

5-Day Professional Training Course | EAW5001

KSA · GCC · Africa

Course Overview

This intensive 5-day training programme on the Engineering Aspects of Welding equips engineers, inspectors, fabrication specialists, and technical managers with the metallurgical knowledge, welding process science, quality assurance frameworks, and code compliance competencies needed to specify, supervise, inspect, and troubleshoot welding operations across complex industrial applications. Welding is not merely a trade skill — it is a precision engineering discipline upon which the structural integrity of pipelines, pressure vessels, offshore platforms, refineries, bridges, and industrial facilities entirely depends. A single deficient weld in a critical application can trigger catastrophic failure with consequences measured in lives lost, assets destroyed, and environmental damage of lasting severity. Across Saudi Arabia's expanding petrochemical and energy infrastructure, GCC construction and fabrication industries operating at a scale matched by few regions on earth, and Africa's rapidly growing oil and gas, mining, and infrastructure sectors where welding quality directly determines asset safety and longevity, the engineering competency to specify, quality-assure, and technically manage welding operations has become a non-negotiable requirement for any serious engineering organisation. Aligned with AWS, ASME, ISO 3834, and EN 1090 welding quality standards, and drawing on the practical realities of welding engineering across the Middle East and Africa, this course elevates participants from observers of welding to authoritative technical leaders of it.

Learning Methods

5-Day Programme Outline

Day 1 — Welding Processes, Fundamentals & Heat Transfer

1. Overview of welding processes: SMAW, GTAW, GMAW, FCAW, SAW, and specialist processes — principles, applications, and limitations

2. The welding arc: physics, energy transfer, and the relationship between electrical parameters and weld quality

3. Heat input calculation and its engineering significance: controlling heat input in critical welding applications

4. Weld pool behaviour: surface tension, viscosity, solidification patterns, and their influence on weld geometry and quality

5. Joint design and weld geometry: butt, fillet, groove, and plug welds — design parameters and their structural implications

6. Welding in hostile environments: wind, humidity, temperature extremes, and overhead welding — challenges common across GCC desert sites and African tropical environments

Day 2 — Welding Metallurgy & Material Behaviour

1. Metal crystal structure, grain boundaries, and the metallurgical basis of mechanical properties

2. The iron-carbon phase diagram: understanding steel behaviour during welding thermal cycles

3. The heat-affected zone (HAZ): formation, microstructural zones, and engineering significance

4. Hardenability and the carbon equivalent: predicting and controlling hydrogen-induced cracking risk

5. Welding of carbon and low-alloy steels: preheat requirements, interpass temperature control, and post-weld heat treatment (PWHT)

6. Welding of stainless steels, duplex alloys, and nickel alloys: special metallurgical considerations for corrosion-resistant materials common in GCC petrochemical applications

Day 3 — Welding Procedure Qualification & Welder Qualification

1. The purpose and structure of welding procedure qualification: why random welding is never acceptable on critical applications

2. ASME Section IX: essential variables, non-essential variables, and supplementary essential variables for procedure qualification

3. AWS D1.1 Structural Welding Code: procedure qualification requirements for structural steel applications

4. Developing a Welding Procedure Specification (WPS): content, format, and engineering judgement in parameter selection

5. Procedure Qualification Records (PQR): test requirements, mechanical testing interpretation, and documentation standards

6. Welder and welding operator qualification: qualification tests, continuity requirements, and management of welder qualification records

Day 4 — Weld Defects, Non-Destructive Testing & Acceptance Criteria

1. Classification of weld discontinuities: planar vs. volumetric defects and their relative structural significance

2. Weld defect causes and prevention: porosity, lack of fusion, incomplete penetration, undercut, hot cracking, and hydrogen cracking

3. Visual inspection of welds: the first and most fundamental quality control tool — techniques, tools, and limitations

4. Non-destructive testing methods: radiographic testing (RT), ultrasonic testing (UT), magnetic particle inspection (MPI), and dye penetrant inspection (DPI) — principles and applications

5. Phased array ultrasonic testing (PAUT) and time-of-flight diffraction (TOFD): advanced NDT for critical weld inspection in pipeline and pressure vessel applications

6. Weld acceptance criteria: interpreting AWS D1.1, ASME VIII, API 1104, and ISO 5817 acceptance standards for different applications

Day 5 — Welding Quality Management, Codes & Project Application

1. ISO 3834 Welding Quality Requirements: parts, requirements levels, and implementation across fabrication organisations

2. EN 1090 execution of steel structures: welding coordination, execution class requirements, and CE marking implications

3. Welding quality plans: content, integration with project quality management, and contractor management

4. Welding documentation and traceability: material traceability, weld maps, weld logs, and as-built records for pressure systems and structural applications

5. Fitness for service assessment: introduction to API 579 and ECA (engineering critical assessment) for evaluating weld defects in operating equipment

6. Capstone: Participants present their Welding Quality Management Plan — including WPS register, ITP, NDT programme, and acceptance criteria matrix — for peer and facilitator review

Regional Relevance

This programme is specifically contextualised for welding engineering professionals operating across KSA, GCC, and African markets. Content integrates Saudi Aramco's welding engineering standards and contractor welding quality requirements including SAES-W series specifications, the Abu Dhabi National Energy Company (TAQA) and ADNOC welding and fabrication requirements governing GCC offshore and onshore energy infrastructure, Qatar Gas and RasGas LNG facility fabrication standards, and the welding quality challenges facing oil and gas, mining, and infrastructure projects across Africa — where the combination of remote site locations, complex materials, limited local welding engineering expertise, and demanding international client specifications creates a uniquely challenging environment for welding quality management.
