Gas Metal Arc Welding (GMAW)

All arc welding processes use an arc to complete a circuit and provide heat for the melting of materials. However, arc welding processes differ in how the arc is produced and controlled, how the molten weld pool is protected from oxidation, and whether it uses a consumable or nonconsumable electrode. In this course, we focus on the process of gas metal arc welding. By the end of this course, you will be able to • Describe the process of GMAW • List common applications for GMAW • Explain the advantages and limitations of GMAW • Describe the four modes of metal transfer • Understand process-specific information and variables
