TIG Welding
TIG Welding (also known as Tungsten Inert Gas welding or GTAW - Gas Tungsten Arc Welding) is a precise type of welding commonly used in automotive and aerospace manufacturing. Think of it as the fine-detail handwriting of the welding world - it creates very clean, strong connections between metals without splatter or mess. Unlike basic welding, TIG welding allows workers to join delicate or thin materials with excellent control, making it perfect for tasks that need to look good and be extremely strong, like car frames or specialized parts. It's considered one of the most skilled types of welding because it requires both hands to work independently - one hand controls the welding torch while the other adds filler metal.

Example Interview Questions
Senior Level Questions
Q: How would you train a new TIG welder on proper techniques?
Expected Answer: A senior welder should discuss setting up proper practice exercises, explaining safety procedures, demonstrating correct torch angle and movement, and methods for checking weld quality. They should mention the importance of starting with simple joints before moving to complex materials.
Q: What quality control measures do you use when TIG welding critical components?
Expected Answer: Should explain visual inspection methods, discuss testing procedures like dye penetrant or x-ray testing, and explain how to prevent common defects. Should also mention documentation and quality standards compliance.
Mid Level Questions
Q: What are the key differences in TIG welding aluminum versus steel?
Expected Answer: Should explain how settings and techniques change between materials, including cleaning requirements, different filler metals, and temperature control. Should demonstrate understanding of common challenges with each material.
Q: How do you set up your TIG welding machine for different materials and thicknesses?
Expected Answer: Should be able to explain amperage settings, tungsten selection, gas flow rates, and how to adjust these based on material type and thickness. Should mention importance of proper preparation and testing.
Junior Level Questions
Q: What are the basic safety requirements for TIG welding?
Expected Answer: Should mention proper protective equipment (helmet, gloves, clothing), ventilation needs, fire safety, and basic electrical safety. Should understand importance of workspace cleanliness and organization.
Q: Can you explain the basic setup process for TIG welding?
Expected Answer: Should be able to describe how to connect gas lines, select proper tungsten, attach ground clamp, and basic machine settings. Should understand importance of material cleaning and preparation.
