6G means the pipe is positioned at a 45o angle.
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.
yes
You multiply the number of welds by the diameter of the pipe that those welds are applicable to.
Your question is incomplete. Which process? Which electrode? What is the basemetal, which position? etc etc
ERW (Electric Resistance Welding) pipe is manufactured by rolling metal and then welding it longitudinally across its length. Seamless pipe is manufactured by extruding the metal to the desired length; hence ERW pipe has a welded joint in its cross-section, while seamless pipe does not have any joint in its cross-section through-out its length.
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 .
Look at a wall. Imagine welding on that wall from left to right or right to left. That is horizontal welding.

5G is a welding position for pipe. The pipe is in a fixed, horizontal position. There is a groove along the circumference of the pipe where the weld is to be made.
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.
In my point you, every 60 degree the welding was carry on.
No 6g is pipe 4G overhead is under d1.1 code structural
It can be. Basic welding techniques can get you started in the welding field. Stick welding in the flat position for example. The more experience you get usually translates to more money. Certain processes take more skill such as TIG or plasma welding as well as pipe welding and underwater welding. These are considered highly skilled.
The pipe which is formed by seam welding.
yes
The pipe must be fixed (not rolled) in the horizontal position. With the pipe horizontal, the weld is vertical. The pipe being fixed requires the welder to weld flat (top), vertical (sides), and overhead (bottom). The pipe must be fixed (not rolled) in the horizontal position.
