Welders need to have great math skills to be successful. If your a welder you will be measuring materials and areas, you will have to be good with fractions, decimals, geometry, volume, area, and trigonometry.

# data[].attributes.body
Fractions and Decimals help you in welding with:
*Reading Blueprints
*Working with penetration depths
*Welding seams together
*Measuring project sizes
*Determining the correct amount of material to use
*Cutting Pipe

Fractions help you work in construction and fabrication so you can determine sizes.

# data[].attributes.body
Decimals allow you to work also with construction and fabrication. Both decimals and fraction are a big part.

# data[].attributes.body
Converting fractions to decimals is really important in welding.

Any form of welding you will be using math it doesn't matter what type of weld your doing you will use math to figure out what your going to weld

A conman formula in tig welding would be:

In welding everything changes depending on the material and the weld your using.

To be a welder you need to have great knowledge with geometry to work with angles, radius, volume, diameter and circumference.

# data[].attributes.body
In welding you use formulas to:
*Calculating shapes and volume
*Determining the pressure and volume of gases
*Figuring out how temperature changes will affect pressure
*Recreating shapes

# data[].attributes.body
For example in Tig welding you use a formula for the gases you use that are Aragon and Co2 it's 75% Aragon and 25% Co2. This makes a perfect combination for you to weld.

Math is used in our daily lives all day long and sometimes you don't even notice it.

This class helped me out with my welding classes with the formulas we used and the geometry we used.
