In 6G the pipe/tube inclination is fixed at a 45° (+/- 5°) and is not rotated. If the welder qualifies in this position they are generally qualified for 1G, 2G, 3G, 4G, 5G, and 6G. Also depending on code and company specification They could be qualified or fillet welds in certain positions.
The 6GR position is in the same inclination and inclination as above, however it has a restriction ring around the pipe/tube. This is used to qualify for T-, K-, or Y- connections.
Welding Electrorodes or Welding Rods are used in arc welding. Arc welding is a special type of welding which uses a welding power supply to create an electric arc between the base material (e.g. steel) and the electrode. The Welding Ectrorodes can be used for all weldable aluminum and mild steel.

how do you calculate welding electrode consumption
shielded metal are welding is also called
The new principal inside welding machines is based on metal-arc welding, whereas the older welding machines used electromagnetic winding to increase the current in welding rods.
In my point you, every 60 degree the welding was carry on.
The meaning of 6G position in Welding is mean that the pipe or test piece inclined to 45 degree and not rotated during welding process .
6G means the pipe is positioned at a 45o angle.

Look at a wall. Imagine welding on that wall from left to right or right to left. That is horizontal welding.
The most common pipe welding testing position is the 6G position, which involves welding at a 45-degree angle while the pipe is in a fixed position. This position tests the welder's ability to perform welds in all directions and is particularly challenging due to the varying angles involved. It is widely used in various industries, including oil and gas, to assess the skills required for complex pipe welds. Other positions like 1G, 2G, 5G, and 6G are also used, but 6G is considered the most rigorous and indicative of a welder's overall competence.
6g
1g = 100cg 6g x (100cg/1g) = 600cg
1g = 100cg 6g x (100cg/1g) = 600cg
6g+3000g - 3006g OR 3.006kg
3/2g + 1/6g = -3 9/6g + 1/6g = -3 10/6g = -3 5/3g = -3 5 = -9g g = -5/9
g = (-1). 18 + 6g = -12g 18 = -12g - 6g 18 = -18g -1 = g
