MIG
MIG (Metal Inert Gas) welding, also known as GMAW (Gas Metal Arc Welding), is a common welding method used in manufacturing and construction. It's like using a metal "hot glue gun" that feeds wire continuously while protecting the weld with shielding gas. Companies prefer MIG welding because it's easier to learn than other methods, works well for many types of metals, and creates clean, strong connections. It's widely used in industries like automotive manufacturing, construction, and general metal fabrication. When you see MIG mentioned in a resume, it indicates the person knows how to operate this type of welding equipment.

Example Interview Questions
Senior Level Questions
Q: How would you train new welders on MIG equipment?
Expected Answer: A senior welder should discuss safety procedures, equipment setup, proper technique demonstration, common mistakes to avoid, and methods for checking weld quality. They should also mention the importance of practice and supervision.
Q: How do you handle complex welding projects requiring multiple types of materials?
Expected Answer: Should explain how to adjust settings for different metals, mention the importance of proper material preparation, and discuss how to prevent problems like warping or contamination.
Mid Level Questions
Q: What safety procedures do you follow when MIG welding?
Expected Answer: Should discuss proper protective equipment (helmet, gloves, clothing), ventilation requirements, fire prevention measures, and equipment inspection procedures.
Q: How do you determine the correct wire feed speed and voltage settings?
Expected Answer: Should explain how material thickness affects settings, describe the sound of a good weld, and mention the importance of test runs on scrap material.
Junior Level Questions
Q: What are the basic parts of a MIG welder?
Expected Answer: Should identify the wire feed system, power source, shielding gas supply, and welding gun, showing basic understanding of how the equipment works.
Q: How do you prepare metal surfaces for MIG welding?
Expected Answer: Should explain cleaning requirements, removal of rust or paint, and proper alignment of pieces to be welded.
