Welding grades are separate requests, not one request
6G and 3G describe welding positions. TIG, MIG and SMAW describe processes. They sit next to each other on a rate card and are routinely confused, but a welder qualified for vertical plate is not automatically right for fixed-position pipe, and a welder who is excellent on carbon steel may not be the right hand for duplex stainless. Saying which grade you need — or describing the joint and material if you are unsure — is the single thing that most improves the match.
