What are the welding locations in space: 1F, 2F, 3F, 4F, 1G, 2G, 3G, 4G, 5G, 6G?

According to Russian standards, space welds are classified according to the following standard:
- Welding (welding) is the welding of the distribution of the plane from 0 to 60 degrees
- Hanging (welded) welds are welds distributed on planes at angles from 60º to 120º.
- Horizontal welds are welds distributed on the planes in the angle of 60º to 120º, welded parallel to the horizontal plane.
- Ceiling welds are welds distributed on planes at angles from 120º to 180º
. Often when welding welder face upward towards the arc so also called welding backstroke.
Welding positions in most cases are divided into welded structures and welded tubes. The structural position is for sheet welded, tubular welding positions are also applied with solder pipes to the plate or to the tilted plane.
Structured welding sites are encoded according to the following rules:
With the first digit representing the welding position:
1: welding position by
2: Horizontal welding position
3: standing position welding
4: ceiling welding position
From the rule above we have the following welding positions:
For welded pipe location and weld type are also classified as follows
The first digit indicates the welding position:
1: Horizontal position and welding welder in welding position by rotating tube
2: Stand position and welders perform horizontal weld.
5: Fixed horizontal pipe position and welded solder, ceiling weld and weld.
6: The pipe is at 45 ° and the welder performs welding in the welding position, horizontal welding, vertical welding and ceiling welding.
The next one shows the weld type:
F: Angle welds.
G: Grooving.
R: Restricted position.
The "R" or restricted position is described in more complex cases.
From the above rule we have the position of welded pipe as follows
