Unit 6 Worksheet: MIG/TIG Welding

Purpose: Practice problems and exercises covering all modules in the MIG/TIG Welding unit. Instructions: Complete all sections. Show your work for calculation problems.

Section 1: Key Concepts Review

Directions: Answer each question in 2-3 sentences.

  1. Describe the fundamental operating principle of mig/tig welding equipment.

  2. What are the three most critical safety considerations when working with mig/tig welding equipment?

  3. Explain how material selection affects the quality of output in mig/tig welding.

  4. Compare and contrast two different techniques or approaches covered in this unit.

  5. Describe the proper startup and shutdown procedure for the primary equipment in this unit.

Section 2: Technical Parameters

Directions: Fill in the parameter table based on what you learned.

Parameter Typical Range Effect on Quality Safety Concern
Primary setting 1
Primary setting 2
Primary setting 3
Material type consideration

Section 3: Troubleshooting Scenarios

Directions: For each scenario, identify the likely cause and propose a solution.

Scenario A: You notice the output quality has degraded significantly compared to your previous session. The equipment settings appear unchanged. What would you check first, and why?

Scenario B: A fellow student reports that the equipment is making an unusual sound during operation. What steps should you take?

Scenario C: The final product does not meet the dimensional specifications required. What factors could contribute to this issue?

Section 4: Safety Protocol Application

Directions: Describe the correct response for each situation.

  1. You discover the primary safety guard is damaged before starting work. What do you do?

  2. A student in your lab group is not wearing the required PPE. How do you handle this?

  3. An emergency occurs during equipment operation. List the first 5 steps you take.

Section 5: Practical Planning

Directions: Plan a complete project using skills from this unit.

Design a project that uses the mig/tig welding skills you learned. Include:

  • Project description (what you will make)
  • Materials needed (with specifications)
  • Equipment settings (with justification)
  • Safety checklist (minimum 5 items)
  • Quality criteria (how you will measure success)
  • Estimated time (broken into phases)
