Welding involves various metallurgical phenomena, including melting, freezing, diffusion, precipitation, thermal strains, and shrinkage. If disregarded or misunderstood, these effects can lead to cracking, porosity, or welds with poor properties. Metallurgy I introduces the fundamental concepts required to understand the metallurgical phenomena that affect welding and welded materials. Topics include the characteristics of atoms, the periodic table, chemical bonding, chemical reactivity, the atomic structure of materials, and the properties of metals.

Frequently Asked Questions
How much do I need to know before taking this course?
No previous knowledge is required to take this course. We start at the beginning, explain every term and topic, and provide practice questions to ensure you understand the material.
Who should take this course?
This course is ideal for both students and professional who want to learn or reacquaint themselves with the basic principles required to understand more advanced metallurgical concepts.
How long do I have to complete this course?
Participants have access to the course content 24 hours a day for a period of 30 days from the date of registration. After this 30-day period, participants will have an additional 10 days to pass the completion exam. The exam can be activated before the end of the 30-day period if the participant has completed all the modules.
Does this course include a completion exam?
Yes. Upon completion of the final course module, participants are prompted to take an exam designed to evaluate their comprehension of the subject matter. The completion exam consists of 50 multiple-choice questions and must be completed within a 90 minute period. Participants who do not attain the 75% passing score may attempt to retake the exam a second time. Participants who attain a score of 75% or more on the completion exam earn an AWS Certificate of Completion and 6 Professional Development Hours (PDHs). The AWS Certificate of Completion can be downloaded and printed directly from the webpage.
Do I need to purchase any other materials?
No. All the materials and resources necessary to complete the course objectives are included.
Do I receive Professional Development Hours (PDHs) for completing this course?
Yes. Participants that receive a score of 75% or above on the Completion Exam will receive an AWS Certificate of Completion and 6 Professional Development Hours (PDHs).
Can I use these Professional Development Hours (PDHs) for recertification?
Yes. Professional Development Hours (PDHs) earned through AWS online courses can be applied towards recertification provided the PDH’s are earned during the certification period.
Do I receive Continuing Education Units (CEUs) for completing this course?
Can I use these Continuing Education Units (CEUs) for recertification?
Will this course help prepare me for the Certified Welding Inspector Exam?
Yes. The Certified Welding Inspector Fundamentals Exam (Part A) contains questions concerning the topics covered in this seminar. This course is designed to help prepare participants for this section of the exam.
