Chapter 20, Problem 1R
What are two ways math is most commonly used in the welding shop?
Expert Solution & Answer
To determine
To Explain: Two ways of math which is used in welding shop.
Explanation of Solution
Mathematics is important in all the areas for calculating the parameters of the operations. In a welding shop, the operator needs to calculate the angles and position of the torch through mathematics.
There are two main ways in which math is most commonly used in welding shop. They are:
- Arithmetic operators: addition, subtraction, multiplication and division.
- Geometrical and trigonometry: Dimensions of the weldments, angle of electrode, point of contact and gap between electrode and work piece.
