Claims (4)
1. Upotreba zaštitnog plina za zavarivanje feritnih čelika volfram-inertnim plinom, pri čemu zaštitni plin sadrži najmanje 99.5 volumenskih % argona ili smjese argon-helij,
naznačena time što
je zaštitni plin tro- ili četvero-komponentna smjesa i, kao i argon ili argon i helij, sadrži doping od 10 do 2000 ppm dušika i 10 do 500 ppm ugljikovog dioksida.
2. Upotreba prema patentnom zahtjevu 1, naznačena time što zaštitni plin sadrži doping između 500 ppm i 2000 ppm dušika i 100 do 300 ppm ugljikovog dioksida.
3. Upotreba prema patentnom zahtjevu 1 ili 2, naznačena time što zaštitni plin ima sadržaj helija od ispod 20 volumenskih %, poželjno ispod 10 volumenskih %.
4. Postupak zavarivanja feritnih čelika volfram-inertnim plinom, kod kojeg se tijekom zavarivanja mjesto zavarivanja pročišćava zaštitnim plinom kako je definirano u bilo kojem od prethodnih patentnih zahtjeva.
