Weld Positions Pipe «UHD 2024»
The pipe is fixed at a 45° angle (inclined). The joint is a beveled groove. The Challenge: Extreme. This single position combines every element of 1G, 2G, and 5G. As you weld around the pipe, you will transition through flat, horizontal, vertical, and overhead welding—all in one continuous bead. The Reputation: Most pipe certification tests (ASME Section IX, API 1104) use the 6G position. If you can pass a 6G test, you can weld any pipe, in any field, in any position. Used for: Universal qualification. Passing a 6G test means you are legally qualified to weld in 1G, 2G, 5G, and 6G.
Before we dive into the specific positions, it is important to understand the shorthand: Indicate the position and complexity.

Complete Guide to Pipe Welding Positions: ASME and ISO Standards
The pipe sits horizontally on its longitudinal axis. The pipe is fixed at a 45° angle (inclined)
The pipe axis is horizontal. The pipe rotates while the welder deposits a horizontal fillet weld.
This feature supports both major nomenclature systems. The logic allows the user to select a standard (ISO or ASME) to populate the correct terminology. This single position combines every element of 1G,
The pipe stands vertically. The welder works from underneath, depositing an overhead fillet weld.
