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. GMAW weld from various positions
3. Demonstrate competent hand-eye coordination necessary to control molten metal and produce aesthetically pleasing appearance and strength 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 GMAW 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 GMAW welding station and wire feeder.
8.   Name common GMAW filler metals and discuss their advantages/disadvantages for welding
      carbon steel alloys.
9.   Summarize shielding gases used in GMAW and describe their characteristics
      and effectiveness.
10. Recall the modes of transfer for GMAW and discuss their characteristics for
      consideration of welding common carbon steel applications.
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.
14. Apply foundational skills to weld carbon steel to industry-based acceptance
      criteria.
15. Label common types of weld discontinuities and examine their root cause and
      prevention measures.
