Welding

This video covers the most important safety rules and protective equipment to use when performing MIG, TIG, arc, and gas welding. Welding helmets and their lens ratings, leather aprons and gloves, welding gas respirators, heat shields, and fire extinguishers are discussed, and various types of welders, including plasma cutters, are illustrated. Correlates to all National CTE Organizational Standards (including the provisions of the Perkins Act). A viewable/printable instructor’s guide is available online. A Shopware Production. Part 2 of the Safety and Technology Series. (22 minutes)

This video puts safety first as it explains how to use a MIG (GMAW) welder. Weld types, welder setup, destructive tests, and general welding techniques are covered. The causes of contact burnback, incomplete fusion, and other problems are identified. A viewable/printable instructor’s guide is available online. Correlates to the standards for the Collision Repair and Refinish Technician Training Certification Program, from the National Institute for Automotive Service Excellence and the National Automotive Technicians Education Foundation.

It was a science first conjured amid the fiery ovens of ancient blacksmiths; today more than 50% of all U.S. products require some form of welding.

There are a lot of similarities between Gas Metal Arc Welding (MIG) and Flux Core Arc Welding, including the use of direct current to provide constant voltage. Viewers will also learn about the different types of electrodes wires used in each outfit. Wire feeders are demonstrated along with the spools that feed them—containing several hundred feet of electrode wire...allowing welders to make long continuous welds. Students see how to position the electrode and how to establish a good weld pool. As in all of the welding videos, safety practices are clearly demonstrated and explained. (11 min.)
