Situational Questions

• 11. What would you do if you discovered a safety procedure was being ignored by your coworker?
  A: I would first address the situation with my coworker and remind them of the importance of following safety procedures. If the issue persists, I would report it to my supervisor to ensure the safety of everyone on the job site.
• 12. If you noticed a piece of equipment malfunctioning, what would you do?
  A: I would immediately stop using the equipment and report it to my supervisor. I would also label the equipment as out of order to prevent anyone else from using it.
• 13. How would you handle a last-minute change in project specifications or deadlines?
  A: I would first communicate with my supervisor to understand the reason for the change. Then, I would adapt my strategy and prioritize tasks to meet the new specifications or deadline.
• 14. If you discovered a mistake in your welding work after it had been inspected and approved, what would you do?
  A: I would immediately report the mistake to my supervisor and work with them to come up with a plan to fix the issue. I would also take responsibility for the mistake and ensure it is corrected in a timely and safe manner.

  A: I have found that open communication and collaboration are key in these situations. I make an effort to understand the perspective of the other trades and work together to find a solution that benefits everyone.

Technical Questions

• 16. What is the difference between MIG and TIG welding?
  A: MIG welding uses a continuous wire electrode and an inert gas to create a weld, while TIG welding uses a non-consumable tungsten electrode and filler metal to create a weld. TIG welding is typically used for thinner materials and provides more precise and clean results.
• 17. What safety measures do you take when welding in confined spaces?
  A: When welding in confined spaces, I ensure proper ventilation is in place and that I have a welding curtain to shield myself and others from sparks. I also wear a respirator to protect against fumes and have a spotter standing by in case of an emergency.
• 18. Can you explain the difference between a fillet weld and a groove weld?
  A: A fillet weld joins two pieces of metal at a right angle, while a groove weld joins two pieces of metal along their edges. Fillet welds are typically used in T-joints, while groove welds are used in corner joints.
• 19. What is the purpose of flux in welding?
  A: Flux removes impurities from the metal being welded and prevents oxidation and contamination of the weld. It also helps create a strong bond between the two pieces of metal.
• 20. How do you prevent warping when welding thick metals?
  A: Warping can be prevented by using clamp techniques, alternating between sides while welding, and using a heat sink to dissipate heat. It is also important to weld with a steady hand and take breaks to allow the metal to cool.
