WLD 202 - MIG & TIG Processes
2 Lecture Hours 2 Lab Hours
Prerequisites: WLD 201
This is a course on the theory and application of gas metal-arc welding (GMAW), flux-cored arc welding (FCAW), and gas tungsten arc welding (GTAW) processes.
Upon successful completion of the course, the student will:
- Set up and shut down gas metal arc-welding equipment.
- Use gas metal-arc welding equipment
- Apply nozzle to work distance and gun travel angle according to metal thickness and wire size.
- Demonstrate the theory and application of flux-cored arc welding.
- Apply welding techniques using the flux-cored arc welding process in the horizontal and vertical up positions.
- Recognize the color code system of Tungsten electrode identification.
- Identify the proper Tungsten to use for various metals.
- Comprehend the proper current and or polarity to set on the power source when using the GTAW welding process.
- Apply various welding techniques when using GTAW welding process in flat and horizontal welding positions.
