Welding is a fundamental engineering discipline used across a wide range of industries, from oil and gas pipelines to structural steel fabrication and industrial plant maintenance. A deep understanding of welding processes, joint configurations, metallurgy, and quality assurance is essential for engineers, technicians, and project personnel involved in design, construction, inspection, or maintenance of welded components.

This course explores the key engineering aspects of welding, including joint design, welding methods, metallurgical behaviour, defect identification, and materials testing. Emphasis is placed on the practical application of knowledge in industrial environments, enabling participants to interpret welding symbols, identify failures, and evaluate weld integrity using both destructive and non-destructive methods.

By the end of this course, participants will be able to:

Understand common welding techniques, terminology, and industrial standards.
Identify various types of welding joints and assess their structural performance.
Interpret welding prints and standardised symbols used in technical documentation.
Analyse basic welding metallurgy and understand material behaviour during and after welding.
Recognise common weld defects and understand their root causes.
Apply mechanical and non-destructive testing (NDT) to evaluate weld quality.
Appreciate the effects of heat treatment and the Heat Affected Zone (HAZ).
Identify safety, reliability, and failure factors related to welding in engineering applications.

This course is ideal for:

Welding engineers and supervisors.
Inspection, QA/QC, and maintenance personnel.
Mechanical, project, and piping engineers.
Technical specialists working in oil & gas, construction, manufacturing, or utilities.
Graduate engineers entering welding or fabrication disciplines.
Anyone involved in the review or execution of welded designs or specifications.

The course follows an applied learning approach using technical lectures, case studies, engineering drawings, hands-on exercises, and practical group discussions. Visual aids, failure samples, and testing demos (where applicable) are used to enhance understanding. Each topic is linked to real-world applications in operations and field environments.

Day 5 of each course is reserved for a Q&A session, which may occur off-site. For 10-day courses, this also applies to day 10
