Weld metallurgy & the HAZ, WPS/PQR/WPQ qualification, essential variables, PWHT, weld defects & acceptance, RT, UT & PT
What you'll learn
Review a WPS, PQR and welder qualification package and judge whether it covers the work in front of you
Apply essential, non-essential and supplementary essential variables, and know what triggers requalification
Identify weld discontinuities and cracking mechanisms - hydrogen, solidification, reheat and lamellar tearing
Explain the welding thermal cycle and the heat affected zone, and why the HAZ is often the weakest region
Select the right NDE method for the expected defect - RT, UT, PAUT, ToFD, MT, PT and VT
Apply preheat, interpass and hydrogen control correctly, and specify PWHT with proper thermocouple control
Assess hardness limits and NACE requirements for sour service, and weld selection for wet H2S resistance
Judge repair welding, controlled deposition and temper bead approaches, and the risks of in-service welding
Understand the arc processes and filler metal classification used on pressure equipment
Inspect before, during and after welding - fit-up, interpass, profile and acceptance criteria
Requirements
No prior welding or metallurgy training is assumed - the metallurgy is built from first principles for engineers
Any engineering, inspection or technical background is enough to follow the course
No welding ticket required - this course is about the engineering and inspection of welds, not manual technique
Helpful but not essential: some exposure to fabrication, pressure equipment or inspection
No software or purchases needed - copies of API 577 and ASME IX are useful alongside the course but not required
Description
A pressure vessel does not usually fail through the plate. It fails at a weld, or in the narrow band of metal beside it that nobody welded but the welding changed anyway.
API 577 is the recommended practice that explains why. It is a source document for the API 510, 570 and 653 examinations, and it is the reference an inspector reaches for when a welding procedure lands on the desk and something about it does not look right.
This course teaches it as working knowledge, not as a document to skim.
WHAT YOU WILL MASTER
Five sections cover welding metallurgy fundamentals, processes and consumables, procedure and performance qualification, weld defects and examination, and special service through repair and quality control.
You will learn what actually happens to steel when you weld it - the thermal cycle, the coarse and fine grained heat affected zones, dilution, residual stress, and why hardness varies across a joint. Then the arc processes, filler metal classification, and the preheat, interpass and hydrogen control that prevent cracking rather than merely reduce it.
THE DOCUMENTS YOU HAVE TO REVIEW
A full section on qualification: the WPS, PQR and WPQ relationship, essential versus non-essential and supplementary essential variables, what mechanical testing a PQR actually requires, welder performance qualification ranges, and continuity. Plus how to review the package systematically and the non-conformances that come up most often.
This is the material that separates an inspector who can read a WPS from one who can tell whether it covers the work in front of them.
DEFECTS AND THE MECHANISMS BEHIND THEM
Porosity, slag, lack of fusion, incomplete penetration, undercut and overlap - and the cracking mechanisms that matter most: hydrogen induced cold cracking and its three conditions, solidification and liquation hot cracking, reheat cracking in creep resistant steels, and lamellar tearing. Then the NDE methods matched to what each actually finds and misses, including phased array and time of flight diffraction.
SPECIAL SERVICE AND REPAIR
Hardness limits and NACE requirements for sour service, welding for wet H2S resistance, hydrogen service, ferrite control in duplex welds, weld overlay and cladding, dissimilar metal welds and carbon migration, and the in-service welding that carries burn-through and hydrogen cracking risk.
WHO THIS IS FOR
Inspection engineers and API 510, 570 or 653 candidates who need the welding knowledge those certifications assume. QA/QC and welding inspection engineers responsible for fabrication and repair quality. NDT technicians who want the code context behind the methods they apply. Mechanical and integrity engineers who specify, review or accept welds. And project and fabrication engineers who need to read a WPS/PQR package with confidence.
WHAT YOU GET
Structured on-demand video across 20 focused lessons and five sections, section quizzes and a final exam, lifetime access on mobile and TV, a certificate of completion, and Udemy's 30-day money-back guarantee.
No prior welding or metallurgy training is assumed - the metallurgy is built from first principles for engineers. No welding ticket required: this is about the engineering and inspection of welds, not manual technique.
