Introduction to 1G to 6G Welding Positions

ALAND WELDING Let you feel the most sincere welding service

Welding is a critical manufacturing process used in a wide variety of industries and fields. When welding, understanding and mastering Welding Positions is crucial because it directly affects the efficiency and quality of the welding process. In the welding process, the symbol system from 1G to 6G is widely used to describe different Welding Positions. These position symbols are not only an important tool for welding engineers and technicians, they are also the basis for welding certification and standardization, providing guidance and standards to ensure welding quality and safety.

1. What do 1G to 6G refer to:

1 to 6G is a standardized Welding Positions symbol system commonly used to describe the position of the workpiece during the welding process. This system is numbered according to the angle and direction of Welding Positions, where:

1G: Flat welding, also called flat position. The welded surface is in a horizontal orientation.

2G: Horizontal welding, also called horizontal position. The surface to be welded is in a vertical orientation, but the electrode is placed horizontally.

3G: Vertical welding, also called vertical position. The surface to be welded is oriented horizontally, but the electrode is placed vertically.

4G: Elevation angle welding, also known as the overhead position. The surface to be welded is in a horizontal orientation, but the welding rod is welded upward.

5G: Elevation horizontal welding, also called upward horizontal welding. The surface to be welded is in a vertical orientation, but the electrode is welded upward.

6G: Elevation angle vertical welding, also called upward vertical welding. The surface to be welded is in the horizontal direction, and the electrode is welded in the vertical direction.

2.1GWelding Positions

1G welding refers to flat welding, also known as flat position welding. In 1G welding, the surface of the workpiece to be welded is in a horizontal direction, and the welding rod is placed horizontally. This position is usually easier to weld because both the electrode and the surface to be welded are in a relatively flat position, making the welding operation relatively simple. 1G welding is common in many welding applications, such as welding joints on flat plates or horizontal surfaces.

3. 2GWelding Positions

2G welding refers to horizontal welding, also known as horizontal position welding. In 2G welding, the surface of the workpiece to be welded is in a vertical orientation, while the welding rod is placed horizontally. This position requires the welder to move vertically while welding, often requiring good hand-eye coordination and skill. 2G welding is common in applications that require welding in a horizontal direction, such as welding horizontal joints of sheet metal.

4. 3GWelding Positions

3G welding refers to vertical welding, also known as vertical position welding. In 3G welding, the surface of the workpiece to be welded is in a horizontal direction, while the welding rod is placed vertically. This kind of Welding Positions requires the welder to weld in the vertical direction, which usually requires better skills and experience, because the gravity of the electrode during the welding process will affect the welding quality. 3G welding is commonly used in applications that require welding in a vertical direction, such as welding vertical pipes or vertical joints.

5. 4GWelding Positions

4G welding refers to elevation welding, also known as upward position welding. In 4G welding, the surface of the workpiece to be welded is in the horizontal direction, and the welding rod is welded upward, that is, the Welding Positions are at the top. This kind of Welding Positions requires the welder to weld at an upward angle, which usually requires certain skills and experience to ensure welding quality and welding speed. 4G welding is often used in applications that require welding from above, such as welding members suspended from ceilings.

6. 5GWelding Positions

5G welding refers to elevation horizontal welding, also called upward horizontal welding. In 5G welding, the surface of the workpiece to be welded is in a vertical direction, while the welding rod is welded upward, and the welding position is in a transverse (horizontal) position. This means that the welder needs to move the welding gun in the horizontal direction and weld in the vertical direction, which requires strong hand-eye coordination and skills. 5G welding is often used in applications that require welding at height, such as welding components located at high altitudes or in difficult-to-access locations.

7. 6GWelding Positions

6G welding refers to elevation vertical welding, also known as upward vertical welding. In 6G welding, the surface of the workpiece to be welded is in the horizontal direction, while the electrode is welded in the vertical direction, and the welding position is in a highly inclined position. This welding position is the most challenging because the welder needs to move the gun both horizontally and vertically and must weld at different angles. 6G welding is one of the standards found in many welding certification exams and usually requires welders to have a higher skill level. 6G welding is typically used in applications that require welding at various angles and positions, such as welding joints in pipes.

Therefore, it is crucial for welding workers to master the welding position symbol system from 1G to 6G. Whether it is flat welding, horizontal welding, vertical welding or the more challenging elevation welding, elevation horizontal welding and elevation vertical welding, understanding the characteristics and requirements of each position can help improve your welding skills and work efficiency. With proper training and practice, welders can better understand and apply these position symbols, thereby ensuring their welding work meets expected quality standards and making a positive contribution to manufacturing and construction projects in a variety of industries.
