What are the fundamental differences in chemical composition among ER309, ER309L, and ER309LSi?All three wires are **austenitic stainless steel** filler metals, primarily composed of **chromium** (around 22-25%) and **nickel** (around 12-14%), making them suitable for welding 309-type stainless stee

Why is ER70S-6 welding wire frequently referred to as "CO2 wire"?ER70S-6 is commonly known as "CO2 wire" because it is designed to be primarily used with **100% carbon dioxide (CO2) shielding gas** in Gas Metal Arc Welding (GMAW), also widely known as **MIG welding**. While it can be used with argon
