 # FABRICATION MATH II ### Fabrication Math II The AWS Fabrication Math II course builds upon the lessons learned in Fabrication Math I to explain the concepts, equations, and formulas that welders, welding foremen, welding supervisors and other welding professionals require to estimate, plan, and produce quality welds. The same type of audio narration, animated graphics, examples, and practice problems found in Math I make these more advanced concepts just as easy to understand and remember. Topics include unit conversions, percentages and ratios, and the calculation of area and volume. Please see the course curriculum for a complete list of topics. ## At a Glance #### Price

• Who should take this course?

Welders, welding foremen, welding supervisors, production managers, welding sales representatives and other welding professionals that require the mathematical skills to accurately measure the physical dimensions of welds and calculate the cost of the labor, materials, and equipment required to produce them.

• Do I qualify to take this course?

The AWS Fabrication Math II Course only requires that learners understand how to add, subtract, multiply and divide whole numbers, fractions and decimals, as well as how to convert fractions, improper fractions, and decimals. These skills are covered in Fabrication Math I.

• 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. Participants are prompted to take a completion exam at the conclusion of the final course module. The exam consists of 50 multiple choice questions designed to test the participant’s retention of the subject matter covered in the course. The Completion Exam must be completed within a three-hour period. Participants that do not attain the 75% passing score may attempt to retake the same exam a second time. Participants who attain a score of 75% or more on the completion exam earn an AWS Certificate of Completion and 15 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 AWS Fabrication Math II Completion Exam will receive an AWS Certificate of Completion and 15 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 1.5 IACET Continuing Education Units (CEUs).

• Will this course help prepare me for the Certified Welding Supervisor Exam?

Yes. The Certified Welding Supervisor Certification Exam contains questions concerning the accurate calculation of weld dimensions and the costs associated with the production of welds. The mathematical skills covered in this course are required to perform those calculations.
