    1. TIG-elektrolucno zavarivanje netaljivom elektrodom u zatitnoj atmosferi inertnog plina TIG-Tungsten Inert Gas GTAW-Gas Tungsten Arc Welding WIG Wolfram Inert Gas schweissen

    2. TIG zavarivanje 1930.g.-Hobart i Devers-zavarivanje u komori ispunjenoj inertnim plinom 1941.g.-Meredith i Pavlecka-prvi TIG gorionik 1942.g. HeliArc welding-zavarivanje Mg legura u zrakoplovnoj industriji

    5. Prednosti Primjenjiv za zavarivanje svih materijala Nema rasprskavanja kapljica Zavarivanje u svim poloajima Zavarivanje u radionici i na terenu Visoka kvaliteta zavara Nema troske, dima i isparavanja Raspon debljina 1-6mm (okvirno!!!) Brzina dodavanja dod.mtr. je nezavisna o energiji elektricnog luka Mogucnost automatizacije

    6. Nedostaci Neekonomicnost za vece debljine (mala kolicina nataljenog materijala) Otean rad na otvorenom (vjetar!) Kvalitetna priprema spoja (geometrija, odmacivanje) Cistoca povrine Utjecaj ljudskog faktora-zavarivac Cijena plina-ako nisu optimalizirani parametri!

    7. Materijali
