Sizing a Tank Type Water Heater
By Randy Lorge
In this interactive learning object, the learner practices sizing a tank-type water heater for one- and two-family residences, townhouses, and apartments with individual water heaters.
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.
