Module: Joining and Cutting Processes (2 of 2)

These PowerPoint slides from the National Center for Welding Education and Training are to be used for a training module on joining and cutting processes for welding. The module is designed for the professional development of welding educators teaching secondary and post-secondary welding programs. Educators may also repurpose the slides for an entire course in welding technology and welding metallurgy, and they may customize the slides to fit their students’ needs.

This course covers the basics and principles of major joining and cutting processes. Advantages, disadvantages, equipment, consumables, techniques, and variables for each process are discussed. Applications, criteria for consumable selection, and how to establish process parameters are emphasized. Laboratory work involves equipment set up and operation of the welding and cutting equipment for specific applications. The module is broken down into the following sections: welding physics and principles, power sources, shielded metal arc welding, gas metal arc welding, flux cored arc welding, gas tungsten arc welding, submerged arc welding, resistance welding, brazing, oxyfuel cutting, plasma arc cutting, air carbon arc cutting, an arc welding process simulation, and electricity.
