In this learning activity you'll recognize potential safety hazards around grinding equipment

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

The learner will understand the design of a planetary gear drive and its advantages and disadvantages.

The learner will gain an understanding of robot motion control by comprehending the fundamentals of the encoder.

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.

In this animated and interactive object, learners follow steps that begin with choosing the correct drive roll and include feeding the electrode wire from the spool to the welding gun.

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.

Learners view wire feed power sources ranging from 110-volt, single phase units to 460-volt, three-phase units. A description and photos of each are provided.

Review your understanding of fumes and particulates safety in welding.

You'll practice identifying and explaining safe practices for grinding

A game to teach you some of the terms you will be using in welding.

Review the electrode classification for dual shield FCAW electrodes.
