What shielding gas or gases work(s) well with electrogas welding? A) Helium (He) B) Nitrogen (N) C) Argon (Ar) D) A mixture of carbon dioxide (CO₂) and argon (Ar)

Question

Quizplus · Accepted Answer

Electrogas welding typically uses a mixture of carbon dioxide and argon as the shielding gas. This combination provides good penetration and spatter control while also minimizing porosity. Helium is not commonly used in electrogas welding and nitrogen is typically only used for certain specialized applications. Argon alone may not provide enough spatter control for this process.
