1. Overview
ANAND ARC ER70S-2 is a triple-deoxidized (Si, Mn, Al) copper-coated mild steel filler wire designed for high-quality TIG/GTAW welding of carbon steels. It is ideal for pipe welding, structural applications, and root passes in thick-walled materials, delivering radiographic-quality welds with excellent mechanical properties 67.
2. Key Features
Material Composition:
Triple deoxidizers (Si, Mn, Al) for welding rusty/dirty surfaces without pre-cleaning 37.
Copper coating ensures smooth arc stability and corrosion resistance 6.
Performance:
Low spatter and stable arc under optimal conditions 6.
All-position welding capability (horizontal, vertical, overhead) 7.
Standards Compliance:
Conforms to AWS A5.18 ER70S-2 and EN ISO 636-A W 42 3 W2Ti 6.
