Does a Welder Need to Have Strong Math Skills?

Did you know that welders need to have strong math skills? It’s true. If you’re thinking about entering the field of welding, you’ll have a decent amount of math in your future. As a welder, you would be measuring materials and areas, so you’ll need to be highly familiar with fractions, decimals, geometry, volume, area, measurements and trigonometry. Don’t let math scare you off, though. If your math skills in high school weren’t very strong, don’t worry—a welding degree program, such as the Associate’s Degree in Welding Occupational Studies at Tulsa Welding School, will help get you up to speed. You’ll be able to take math classes along with your welding classes. So, what kind of math does a welder need?

Fractions and Decimals in Welding

Fractions and decimals allow you to work in either construction or fabrication so you can determine sizes. Being able to convert fractions to decimals means you’ll need to know computational fractions. Fractions and decimals have several applications in welding:

• Reading blueprints
• Working with penetration depths
• Welding seams together
• Measuring project sizes
• Determining the correct amount of materials to use
• Cutting pipe

Geometry in Welding

A welder needs to have a strong knowledge of geometry in order to work with angles, radius, volume, diameter and circumference. A part of this work means a welder needs to know how to use drafting tools and a compass. With this knowledge, a welder will be capable of executing the following tasks that are integral to the trade:

• Forming accurate joints
• Measuring and creating angles
• Finding the correct proportions of a circle when welding circular objects

Formulas in Welding

Knowledge of formulas isn’t restricted to mathematicians or engineers. An experienced welder relies on accurate formulas so he or she can carry out several critical operations:

• Calculating shapes and volume
• Determining the pressure and volume of gases
• Figuring out how temperature changes will affect pressure
• Recreating shapes

Trigonometry in Welding

Don’t let this one scare you away. If you are going to be a successful welder, you need to have a beginning understanding of some of the operations of trig like sine, cosine and tangent. If you have trouble grasping trig, tutors can help you catch up. Trigonometry will help you in several areas of welding:

• Calculating degrees for accurate angles
• Determining the length of each side of a shape being replicated
• Finding the theoretical strength of a weld

The Value of Math in Welding

Good welders use basic and advanced math to be able to carry out several welding operations every day. Knowing whole numbers, fractions, converting to decimals, how to calculate volume and area, using geometry to determine angles and using tangents, sine and cosine all make a welder a critical member of any construction team or company. Some of these math skills can be learned in high school while others can be learned in a professional welding program.
