2. Carbon steel has a melting point that is roughly: → 2780° F
3. What are the five basic weld joint types recognized by AWS? → Butt, corner, tee, lap, and edge
4. Which movement skill involves transferring weight smoothly from one foothold to another without bouncing or hesitation? → Silent feet
5. Why is regular inspection of climbing equipment important? → Detect wear and prevent failure
6. How should an inspection report be corrected? → Single-line out the error, correct the error, date, and initial
7. Why is patience important for climbing instructors? → Support and build trust
8. What equipment is essential for rescue operations? → Ropes and communication
9. What is the MOST effective way for new CWI professionals to build competency? → Combining formal education, mentored practice, and ongoing professional development

11. What role does practice play in skill development? → Reinforces and builds confidence
12. How does proper footwear contribute to climbing safety? → Provide grip and protection
13. What is the PRIMARY purpose of obtaining CWI certification in Climbing Wall Instructor? → To demonstrate verified competency and adherence to professional standards
14. When conducting a risk assessment for CWI operations, which factor should receive the HIGHEST priority? → Probability and severity of potential harm
15. The discontinuity that arises from the gas being trapped inside the weld cross-section is known as → Porosity
16. What is the benefit of building rapport with clients? → Enhance trust and cooperation
17. Which of the following is a defining characteristic of the Submerged Arc Welding (SAW) process? → A blanket of granular flux covers the arc and weld pool.
18. Which foundational principle is MOST important for success in Climbing Wall Instructor? → Commitment to continuous learning, ethical practice, and quality outcomes
