Introduction to Gas Metal Arc Welding (MIG) (65 Hours) 

Course Description: “Introduction to Gas Metal Arc Welding” will cover the basic theory and hands on practice, as well as common operation procedures needed to perform the GMAW process. Understanding of the different modes of electrical transfer within the GMAW process and how to achieve those modes in relation to the welding variables and machine settings. Definitions and terminology commonly used in GMAW. Basic understanding of symbols used in welding. Opportunity for students to qualify under D1.1 Structural Code in the 1G position.

Course Objectives: Upon completion of the course, students will be able to

  • Define GMAW
  • List the advantages and disadvantages of the GMAW process
  • Describe the electrical components of the GMA welding equipment
  • Describe the parts of the GMAW wire feeder system.
  • Describe the parts of the GMAW gun
  • Distinguish between the different types of electrical transfer modes
  • Proper electrode selection/classification
  • Identify an electrode by using the AWS numbering system for electrode classification
  • Basic weld symbols/reading the welding symbol
  • Describe how to safely remove/install new wire spools onto the GMAW feeder systems
  • Describe the proper current selection for different GMAW applications
  • Describe the type of power source required to perform GMAW
  • Describe proper amperage/voltage requirements for GMAW
  • Explain proper joint preparation and the 5 joint types
  • Explain the 4 different welding positions associated with GMAW
  • Troubleshooting associated with GMAW equipment
  • Basic visual weld inspection/types of defects associated with GMAW
