Final answer:
Argon/helium binary blends are useful for welding stainless steels and aluminum.
Step-by-step explanation:
Argon/helium binary blends are commonly used for welding stainless steels and aluminum. These blends provide a shielding gas that protects the weld from atmospheric contamination and helps to prevent oxidation. The argon gas in the blend helps to stabilize the arc during welding, while the helium gas offers a higher heat input, allowing for deeper penetration and faster welding speeds. The use of these binary blends improves the overall quality and efficiency of the welding process.
