In this interactive object, learners read an explanation of the electrodes used for welding with the GMAW and FCAW processes. In two matching exercises, students test their knowledge of classification and specification numbers.

The learner will understand and be able to apply the common welding variables of the GMAW process.

The learner will identify components of a welding robot and determine if the robot is set up correctly to avoid singularity.

In this learning object, you’ll explore what tools should be a part of every welding tool bag.

Learners review the process for calculating board feet and use virtual samples to practice the process.

Learners read how to use a lumber rule to quickly and accurately estimate board feet. They then use virtual samples to practice the process.

In this learning object the student will learn how to measure a stain and calculate angles of impact. Determining the angle of impact for bloodstains takes advantage of the trigonometric functions (Sine function).

A mathematical relationship exists between the width and length of an elliptical bloodstain which allows for the calculation of the angle of the impact for the original spherical drop of blood.

Given well formed stains we can accurately measure the width and length by simply dividing the stain along it’s major and minor axis. The opposite halves would be generally equal to each other which aids in establishing the impact angle.

This is an animated troubleshooting exercise that takes voltage measurements to determine the fault of three different series circuits. There are six review questions that enable the learner to determine the effectiveness of the troubleshooting presentation.

Learners examine the function of the analog wattmeter to measure true power, how it is connected in a circuit, and how the internal components develop a measurement. A brief quiz completes the activity.

Test your knowledge of measurement by answers the questions!
