ASA Welding Questions and Answers Graded A+ What is the difference between MIG welding and TIG welding? MIG welding uses a continuous wire feed as an electrode, while TIG welding uses a non- consumable tungsten electrode and requires a filler material to be added manually. What safety equipment is essential for welding operations? Welders should use protective gear, including a welding helmet, gloves, and flame-resistant clothing. What does the term "penetration" refer to...
