In the Shielded Metal Arc Welding (SMAW) process, the gas that is primarily released to provide a shielding effect on the molten weld pool is **hydrogen**. This gas is produced from the moisture in the flux coating of the electrode during the welding process. While other gases like argon may be used in different welding processes (like TIG welding), hydrogen plays a significant role in the SMAW process specifically.
