Beschreibung
Zusammenfassung:	The invention discloses a high-cleanliness gas shielded alloy welding wire steel wire rod and a preparation method thereof. According to the preparation method disclosed by the invention, through integrated innovation of multiple processes such as chemical component design, converter smelting, a deoxidation alloying process, tapping slag washing, LF furnace refining, VD furnace vacuum refining, continuous casting, steel rolling heating schedule, controlled rolling and stelmor controlled cooling, the preparation method has the characteristics of high process applicability, high controllability and the like, and the produced ER70S-6 alloy welding wire steel wire rod is high in steel cleanliness, low in production cost and high in production efficiency. According to the present invention, the steel wire rod has characteristics of less inclusions, low gas content (O < = 0.0015 wt%, N < = 0.0020 wt%), section shrinkage of more than or equal to 85%, excellent plasticity, excellent toughness and excellent drawing de
