This activity is a simulation that allows the learner to practice personal protective equipment tasks.

In this interactive object, learners review how to read a caliper. They then test their skills with eight practice questions.

In this learning activity, you’ll explore the characteristics of common, carbon steel shielded metal arc welding electrodes, which fall under American Welding Society specification A5.1.

In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.

In this learning activity you'll examine a stateful packet inspection firewall that keeps track of legitimate Internet service requests, also known as dynamic packet filtering.

In this learning activity you'll review a text and visual overview of metric measurement.

This project sheet outlines the steps for coolant inspection and charging.

In this interactive object, the learner reads an explanation of how various shielding gases are used in GMAW and FCAW. An exercise 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.

You'll practice identifying and explaining safe practices for grinding

Review the concepts of safety for Welding
