If the husband has been authorized to work visa by the US government, let us say it's an H-2B temporary work visa, then the wife may accompany her husband as an H-4 visa holder. There is no need for a tourist visa. She goes to the consulate with her husband's visa approval documents, her birth and marriage certificates, along with a valid South African passport, and she should be issued the appropriate H-4 visa.
