In this learning activity you'll examine the terms associated with a grouped frequency distribution and follows the steps to construct a grouped frequency distribution using manual methods.

The learner will...review the process for successfully completing a weld procedure specification for weld testing in the educational setting.

Robotic welding allows welders to create more consistent and higher quality welds. But, it requires you to understand the terminology associated with its programs. Watch this module to review terminology associated with robotic arc welding and the weaving process.

Learners study the factors that determine the frequency of an AC generator, such as the rotational speed of the armature or the number of stator poles.

Students read the vocabulary associated with frequency response as it relates to an amplifier.

In this learning activity you'll explore the operation of frequency division using several different types of counters.

Learners read how to use the knobs and the output terminals of a Wavetek Model 25 function generator to obtain a waveform at a desired frequency.

Learners follow the steps required to construct an ungrouped frequency distribution using either manual methods or a spreadsheet.

Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.

In this interactive object, learners read the definitions of terms associated with the construction of a grouped frequency distribution. A brief quiz completes the activity.

Students view a video that shows the correct methods for starting a GTAW weld pool and adding filler. It focuses on the two problems that many students have – adding filler too soon and angling the torch so that the filler melts prematurely on the filler rod. Note: This activity is 3.6 mb.

Students learn how to predict how circuits will respond to varying frequency. They solve for the magnitude and phase angles.

This module will guide you thru the use of welding coupons in the welding process.

Explore welding electricity fundamentals including electron theory, parts of a circuit, welding power sources, and types of current.

Learners follow steps to establish the lower and upper limits in a spreadsheet.

Students follow step-by-step directions for entering data into a spreadsheet and reporting the results.

Learners follow steps to establish class boundaries and tally the data using a spreadsheet.
