WELDING FUNDAMENTALS III

The Fabrication Math II course is ideal for:

• Welders 
• Welding foremen 
• Welding supervisors 
• Production managers 
• Welding Sales Representatives 

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.

This course teaches students how to:

• Express percentages as fractions
• Convert fractions into decimals
• Find percentages of whole numbers
• Explain the use of ratios
• Calculate and simplify ratios
• Explain the use of rates
• Calculate unit rates
• Calculate rates of speed, distance, and time
• Explain the use of exponents
• Describe how exponents are used in powers of 10
• Describe how exponents are used in scientific notation
• Explain the order of operations in mathematics
• Describe how to accurately perform calculations in the correct order
• Explain the use of conversions
• Describe United States Standard Units
• Describe the metric system
• Convert US Standard Units to metric units and vice versa
• Describe the measurement of temperature
• Explain the difference between Fahrenheit and Celsius
• Convert Fahrenheit to Celsius, and vice versa
• Explain measurements of time and how to convert them
• Explain the use of lines, line segments, endpoints, rays, parallel, and perpendicular lines
• Explain the use of angles and degrees
• Calculate angles
• Explain two dimensional shapes
• Calculate the area of 2 dimensional, rectangular shapes
• Explain the different types of triangles
• Calculate the area of a triangle
• Explain the Pythagorean theorem
• Explain Heron’s Formula
• Calculate the area of non-right triangles
• Calculate the radius, diameter, circumference, and area of a circle
• Calculate the volume of three-dimensional shapes
• Describe the parts of a cone
• Calculate the volume of a cone
• Calculate the surface area of a cone
• Calculate the volume of a cylinder
• Calculate the surface area of a cylinder

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
