Welding Positions For Pipe

In the 2G position, the pipe is fixed vertically (standing up). The axis of the pipe is vertical, but the weld is deposited horizontally around the circumference.

In pipe welding, positions are standardized by the American Welding Society (AWS) and ASME Section IX to define how a welder interacts with a joint based on pipe orientation and mobility. These classifications (1G, 2G, 5G, 6G) determine the level of skill required and the specific techniques needed to manage the molten weld puddle against gravity. 2. Standard Pipe Welding Positions welding positions for pipe

The following table summarizes the primary positions used in the industry: Orientation Pipe Status Description Horizontal Rotated In the 2G position, the pipe is fixed

The pipe is rotated (manually or by a machine), allowing the welder to stay in one spot. These classifications (1G, 2G, 5G, 6G) determine the

Disclaimer: Always refer to the specific welding procedure specification (WPS) for your job. Positions vary slightly between ASME, API, and AWS codes.

It is the easiest because the welder is always working in the "flat" position on the top of the pipe, where gravity helps pull the molten puddle into the joint. 2G: Vertical Position In the 2G position , the pipe stands upright like a column. Orientation: The pipe axis is vertical.

In the 1G position, the pipe is placed horizontally on a rolling bed or turner. The pipe rotates while the welder remains stationary. The welder applies the weld metal from above, typically at the 12 o'clock position (top dead center).
