Course Overview
Welding Metallurgy, Defects & Failure Analysis
Understand how welding changes material behaviour — and how those changes contribute to defects, cracking, and structural failure.
Understand weld metallurgy, heat-affected zones, residual stress, common weld defects, inspection, cracking mechanisms, and weld-related failures.
Why This Course Matters
A weld is simultaneously a joint, a thermal cycle, a metallurgical transformation, and a geometric stress concentrator. Failures can originate from weld metal, the heat-affected zone, residual stress, hydrogen, poor procedure control, or service loading.
Materials and failure decisions sit at the intersection of design, manufacturing, loading, environment, inspection, and service history. Professionals who can identify damage mechanisms and interpret physical evidence bring greater clarity to reliability, integrity, and root-cause decisions.
This course is designed to close that capability gap with structured, engineering-focused learning that strengthens both technical understanding and professional judgement.
What This Training Helps You Achieve
Understand weld metallurgy, heat-affected zones, residual stress, common weld defects, inspection, cracking mechanisms, and weld-related failures. The training is designed to help you apply this knowledge with greater confidence across materials selection, inspection, failure investigation, structural integrity, and life assessment, while making assumptions, limitations, and technical reasoning easier to explain and defend.
Why Engineers Take This Course
Understand how welding changes material behaviour
Develop stronger capability in welding processes and thermal cycles, and use that understanding to support more credible decisions in materials selection, inspection, failure investigation, structural integrity, and life assessment.
Recognise weld defects and cracking mechanisms
Develop stronger capability in hydrogen cracking, hot cracking, lamellar tearing, and other weld defects, and use that understanding to support more credible decisions in materials selection, inspection, failure investigation, structural integrity, and life assessment.
Investigate weld-related failures systematically
Develop stronger capability in preheat, post-weld heat treatment, procedure control, and prevention strategies, and use that understanding to support more credible decisions in materials selection, inspection, failure investigation, structural integrity, and life assessment.

Why Build This Skill Now
Engineering teams are expected to make faster decisions while still demonstrating sound technical judgement, traceability, and awareness of risk. Building capability in welding metallurgy, defects & failure analysis gives you a stronger basis for reviewing assumptions, challenging weak conclusions, and contributing more effectively when technical decisions matter.
If you want to strengthen your understanding of this subject, improve the quality of your engineering judgement, and build capability that can be applied across real projects, this course is a strong next step.
