Metallurgy I
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.

Upon completion of Metallurgy II, students will be able to:
- Explain the metallurgical phenomena that affect welding and welded materials, including melting, freezing, diffusion, precipitation, thermal strains, and shrinkage
- Demonstrate an understanding of the characteristics of atoms, the periodic table, chemical bonding, and chemical reactivity, and explain how they relate to metallurgy
- Analyze and interpret the atomic structure of materials, including crystal lattices, and describe how they impact the properties of metals
- Identify and apply the appropriate heat treatments and stress relief techniques required to prevent cracking, porosity, or welds with poor properties
- Discuss the material properties of metals, including ductility, malleability, strength, and toughness, and explain how they are affected by metallurgical phenomena
- Classify elements based on their properties and describe the characteristics of ionic bonding and corrosion
- Evaluate the atomic characteristics of the four states of matter and explain how they relate to metallurgical phenomena
- Apply the fundamental concepts of metallurgy to design, fabrication, or inspection of welded, brazed, or soldered joints
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?
Yes. Participants that receive a score of 75% or above on the Completion Exam will receive an AWS Certificate of Completion and 0.6 IACET Continuing Education Units (CEUs).
-
Can I use these Continuing Education Units (CEUs) for recertification?
Yes. Continuing Education Units (CEUs) earned through AWS online courses can be applied towards recertification provided the CEUs are earned during the certification period.
-
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.
-
What platforms and devices can I use to view AWS Learning online courses?
You must be connected to the internet to access AWS Learning online courses. AWS supports the most recent versions of Google Chrome, Firefox, Safari, and Internet Explorer. Courses can be viewed on desktops, laptops, tablets, and mobile phones. Note, however, that a high speed internet connection and large screen offer a better user experience.
