That is fine. Aanyway, I didn't send in the information for the award.

Just to give you the description in English:
1G - welding in the FLAT position or what we would normally call "downhand"
2G - qualified to weld in HORIZONTAL position
3G - in the VERTICAL position (there is a difference between upwards & downwards welding)
4G - in the OVERHEAD position
5G - welding of a FIXED pipe or section in the HORIZONTAL position
6G - welding of a FIXED pipe or section in the INCLINED position
6GR - same as 6G but pipe or section has a RESTRICTING plate which qualify welder for T, K & Y connections

Not sure what else you wish to know (in English)

Attached position of 1G to 4G welder qualifications positions, 5G - 6GR positions to be send later...

Attached 5G to 6GR, note the "R" on 6GR means restricted. Welders can also be qualified on 1F - 4F using plates, 5F can be qualified using pipes.

Exactly right. This is AWS code and I shouldn’t duplicate the description from 6th floor, Let me add something. LR and ISO has difference code for it, refer to attached,
