>>5794899When I went to the Technology I. exam the professor gave me 2 questions one was about mechanical cleaning of materials and the other one was about welding. He wanted me to tell him about TIG welding and casually mentioned that I should tell him about WIG as well and compare them. When i smirked at that question, he told me that I wouldn't believe how many students would swear to god they are totally different things. Pretty cool guy.
