Learners study the types of symbols used on a P&ID diagram to indicate instruments. A quiz completes the activity.

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

Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.

Learners examine the different types of lines used on a P&ID diagram and the types of connections they represent. They test their knowledge in a matching exercise.

Learners examine the symbols and values that control surface roughness, waviness, and lay. A brief quiz completes the object.

In this learning activity you'll read introduction to electrical quantities, units, and symbols and test their knowledge in a matching exercise.

In this learning activity you'll review various types of common components used in electronics and view their schematic diagram symbols.

The schematic symbols of logic gates used in digital circuits are shown.

The Groove Weld Bend Test

In this interactive object, learners test their knowledge of 14 geometric tolerance control symbols.

Fillet Weld Break Test

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.

Fillet Weld Acid Etch Test

In this interactive object, learners view the icons and symbols used most frequently in value steam mapping. A matching activity completes the object.

The learner will understand how to properly use a fillet gage to measure weld size.

In this learning activity you'll review different math symbols and identify them in a matching exercise.

Learners read definitions of atomic symbols, atomic numbers, and mass numbers and then answer questions about the number of neutrons, protons, and electrons in select elements.

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

Students read about the six common terms used to represent the powers of ten in the field of electronics and complete two matching exercises.

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