COURSE CONTENT

Student Learning Outcomes:
Upon completion of the course, students will be able to:
Untitled document
1. Demonstrate safe use of the tools and equipment in a welding shop.
2. GTAW weld in various positions.
3. Demonstrate competent hand-eye coordination necessary to control molten metal and produce aesthetically pleasing appearance and strength in various metals.
 

Objectives: Untitled document
Students will be able to:
1.   Categorize the personal traits that employer look for in their employees.
2.   Describe the GTAW process and list the other terms used to identify the process.
3.   Evaluate safety issues as they pertain to shop safety, industrial safety, and personal safety
      and apply appropriate safety protective measures.
4.   Recall common terminology used in the application of welding operations.
5.   Organize common weld joint considerations and list the types of welds that can be applied to
      each joint.
6.   Analyze welding operation requirements for common applications and select the proper
      power source.
7.   Correctly assemble the parts of a GTAW welding station and GTAW torch.
8.   Name common GTAW tungsten electrodes and discuss their advantages/disadvantages for
      welding common metal alloys.
9.   Identify common AWS filler metal specifications/classification and discuss how they apply
      to different alloy metals.
10. Summarize shielding gases used in GTAW and describe their characteristics and
      effectiveness.
11. Examine related equipment maintenance requirements and apply correct tasks to ensure safe
      and effective operation.
12. Demonstrate pre-weld procedures and apply correct welding parameter adjustment tasks.
13. Employ pre-weld metal preparation techniques to ensure weld quality.
