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.

Upon completion of the Fabrication Math II course, students will be able to:

  • Explain and apply percentages to welding-related calculations
  • Convert between percentages, fractions, and decimals
  • Calculate ratios and unit rates and use them to solve welding-related problems
  • Use exponents and scientific notation to represent very large or very small numbers that may arise in welding calculations
  • Accurately perform calculations using the order of operations
  • Convert between different units of measurement, including US Standard Units and the metric system, and apply these conversions to welding calculations
  • Describe and use basic geometry concepts, such as lines, angles, and two-dimensional shapes, to solve welding-related problems
  • Calculate the area and perimeter of two-dimensional shapes, such as rectangles and triangles
  • Apply the Pythagorean theorem and Heron's formula to calculate the area of non-right triangles
  • Calculate the circumference, area, and volume of circles, cones, and cylinders, and apply these calculations to welding-related problems

Frequently Asked Questions

  • 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?
