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 processes of electroslag welding and
electrogas welding.
By the end of this course, you will be able to
• Describe the processes of ESW and EGW
• List common applications for ESW and EGW
• Explain the advantages and limitations of ESW and EGW
• Understand process-specific information and variables
