flat welding positions

13
FLAT WELDING POSITION : Welding in this position is commonly known as the *1G, a welding application on plate joints or other rebars., * 1F, a welding application on a V shaped metal joints, similar to an inverted T-joint., * 1G Pipe, a welding application on a pipe horizontally rolled, its like rotating the pipes being joined to a clockwise or counter cloclwise and depositing the weld at or near the top. This is the most basic and easiest welding position there is. HORIZONTAL WELDING POSITION : Welding in this position is known as the *2G, the plates or bars to be welded are on a standing or vertical position and the weld application is applied horizontally., *2F, a welding application on a standing or erect position of a T joint for example and still the axis of weld is horizontal., *2G Pipe, a welding position when the pipes to be joined is in a vertical or standing position, still the weld application is horizontal. This position is slightly harder to do than the flat weld position as gravity is trying to pull the molten metal down towards the ground, but with continues practice, it will still be easy to do. VERTICAL WELDING POSITION : Welding in this position is commonly known as *3G, weld applications here is done in a vertical manner, going up in this position is known as Vertical Up weld, and going down in this position is known as Vertical Down weld. Plates to be joined here is in a vertical position., *3F, weld application here is the same like the 3G but the difference in the metal joint being welded. It is like a T joint where the metal is in a standing or erect position and weld is applied on the most corner joint of the metal in a vertical up or vertical down manner., *5G Pipe, a welding position on a pipe that is horizontally fixed, weld application on the joint is from the top going down and overhead, the same on the other side. Note here that the pipe is fixed and shall not or cannot be rotated when welding. This is one position that many encounter difficulty specially the vertical up weld due to gravity compared to the vertical down weld which is easier to control. This kind of application has a limited penetration. OVERHEAD WELDING POSITION : Welding in this position is known as just that, above the head welding applications. But also known or reffered as to the *4G, the plates here to be welded is positioned overhead or above the head and weld application is usually in a horizontal manner., *4F, this is similar to the T joint literally where in the joint to be welded is overhead or above the head and the weld is applied in the very corner of the metal joint and the axis of weld is horizontal. *6G, this pipe welding position, is an overhead or above the head weld application and the pipe is fixed and cannot be rotated. I will do some graphic renditions of its different position and will post it later for a better visual and easier understanding. Last edited by rosy; 03-26-2012 at 02:18 PM. #27 04-07-2012, 08:46 PM

TRANSCRIPT

Page 1: Flat Welding Positions

FLAT WELDING POSITION :   Welding in this position is commonly known as the *1G, a welding application on plate joints or other rebars.,* 1F, a welding application on a V shaped metal joints, similar to an inverted T-joint.,* 1G Pipe, a welding application on a pipe horizontally rolled, its like rotating the pipes being joined to a clockwise or counter cloclwise and depositing the weld at or near the top.

This is the most basic and easiest welding position there is.

HORIZONTAL WELDING POSITION :   Welding in this position is known as the *2G, the plates or bars to be welded are on a standing or vertical position and the weld application is applied horizontally.,*2F, a welding application on a standing or erect position of a T joint for example and still the axis of weld is horizontal.,*2G Pipe, a welding position when the pipes to be joined is in a vertical or standing position, still the weld application is horizontal.

This position is slightly harder to do than the flat weld position as gravity is trying to pull the molten metal down towards the ground, but with continues practice, it will still be easy to do.

VERTICAL WELDING POSITION : Welding in this position is commonly known as *3G, weld applications here is done in a vertical manner, going up in this position is known as Vertical Up weld, and going down in this position is known as Vertical Down weld. Plates to be joined here is in a vertical position.,*3F, weld application here is the same like the 3G but the difference in the metal joint being welded. It is like a T joint where the metal is in a standing or erect position and weld is applied on the most corner joint of the metal in a vertical up or vertical down manner.,*5G Pipe, a welding position on a pipe that is horizontally fixed, weld application on the joint is from the top going down and overhead, the same on the other side. Note here that the pipe is fixed and shall not or cannot be rotated when welding.

This is one position that many encounter difficulty specially the vertical up weld due to gravity compared to the vertical down weld which is easier to control. This kind of application has a limited penetration.

OVERHEAD WELDING POSITION :   Welding in this position is known as just that, above the head welding applications. But also known or reffered as to the*4G, the plates here to be welded is positioned overhead or above the head and weld application is usually in a horizontal manner.,*4F, this is similar to the T joint literally where in the joint to be welded is overhead or above the head and the weld is applied in the very corner of the metal joint and the axis of weld is horizontal.*6G, this pipe welding position, is an overhead or above the head weld application and the pipe is fixed and cannot be rotated.

I will do some graphic renditions of its different position and will post it later for a better visual and easier understanding.

HERE ARE THE GRAPHIC RENDITIONS OF THE DIFFERENT WELDING POSITIONS as promised in my last post dated March 26, 2012 :

I'm pretty sure bro kabasor is very familiar with these various welding positions as he is a graduate of TESDA welding courses, I'm just not sure up to what NC certification he has manage to reach or finish. These graphic illustrations were based from the booklet given to a friend of mine who also graduated from TESDA welding courses. I have just re drawn the graphics in the booklet for a clearer picture and easy understanding, though I positioned some illustrations in different angles.
