Welder project issues

Can a welder’s certificate for TIG welding be used for either pure TIG welding or pure shielded metal arc welding? For example, this welder: GTAW-FeⅣ-6G-3/76-Fefs-02/10/12& SMAW-FeⅣ-6G(K)-9/76-Fef4J
FeⅣ and FeII represent the materials
It’s possible, but there are requirements regarding weld thickness: for TIG welding, the maximum weld thickness is 6 mm, while for shielded metal arc welding it is 18 mm
The GTAW process can only be used to weld stainless steel materials 6 mm (inclusive) or thinner； The SMAW process can only be used for welding stainless steel materials with a thickness of 18 mm or less, either with backing plates or after TIG welding as a base layer.
