MIG (Metal Inert Gas)
MIG welding, or Metal Inert Gas welding, is a popular way of joining metals together used extensively in set construction. Think of it like a high-tech hot glue gun for metal. It uses electricity to melt metal wire while protecting the weld with a special gas to make clean, strong connections. Set builders prefer MIG welding because it's easier to learn than other welding types, works well for different thicknesses of metal, and creates neat-looking welds that might appear on camera. It's also called "wire-feed welding" or "GMAW (Gas Metal Arc Welding)" in job descriptions, but MIG is the common term most people use.

Example Interview Questions
Senior Level Questions
Q: How would you approach welding aluminum set pieces that will be visible on camera?
Expected Answer: A senior welder should discuss techniques for clean, camera-ready welds, including proper gas mixture selection, machine settings, and surface preparation. They should also mention considerations for preventing warping and maintaining aesthetic appearance.
Q: How do you manage a team of welders working on a time-sensitive production?
Expected Answer: Should discuss project planning, task delegation, quality control processes, safety protocols, and strategies for meeting tight deadlines while maintaining quality standards.
Mid Level Questions
Q: What safety procedures do you follow when MIG welding on a busy set?
Expected Answer: Should mention proper ventilation, fire safety measures, protective equipment, securing work areas, and communication with other crew members.
Q: How do you ensure your welds will be strong enough for mobile set pieces?
Expected Answer: Should discuss proper material preparation, choosing correct wire and settings, testing procedures, and understanding load requirements for moving set pieces.
Junior Level Questions
Q: What are the basic components of a MIG welder?
Expected Answer: Should be able to identify and explain the wire feed system, gas cylinder, power source, and basic controls for voltage and wire speed.
Q: How do you prepare metal surfaces before welding?
Expected Answer: Should describe cleaning methods, removing rust or paint, proper fit-up of pieces, and basic safety checks before starting to weld.
