Can the welding certificate of argon arc welding be dry welding and pure manual welding?

You should be talking about the welder's operation certificate issued by the emergency management bureau, which is the IC card. This certificate is a necessary certificate for welders to work. Without this certificate, they are not allowed to work. This certificate is required for both dry argon arc welding and dry manual welding. But the technical requirements of argon arc welding and manual welding are different. If you can't do it, you need to go through corresponding training before you can take up your post.
