Types Of Welding Positions ((new)) [ 2025 ]

Standards for welding positions are defined by the and the American Society of Mechanical Engineers (ASME) .

In the world of fabrication, refer to the orientation of the weld joint relative to the welder’s body and the gravitational pull on the molten metal. Understanding these positions is critical because they dictate the required technique, heat settings, and travel speed needed to ensure a structurally sound weld.

The American Welding Society (AWS) and the American Society of Mechanical Engineers (ASME) classify these positions using a numbering and lettering system: for groove welds (butt joints) and "F" for fillet welds (T-joints or lap joints). 1. Flat Position (1G and 1F)

| Position | AWS Code | Gravity Effect | Difficulty | |----------|----------|----------------|-------------| | Flat | 1G / 1F | Helps (pulls into joint) | ★☆☆☆☆ | | Horizontal | 2G / 2F | Moderate hindrance | ★★☆☆☆ | | Vertical | 3G / 3F | High hindrance | ★★★★☆ | | Overhead | 4G / 4F | Severe hindrance | ★★★★★ | | Fixed Pipe (5G) | 5G | Variable | ★★★★★ | | Inclined Pipe (6G) | 6G | Variable | ★★★★★★ | Standards for welding positions are defined by the

This is considered one of the more difficult positions for beginners. Both the workpiece and the weld axis are vertical or near-vertical.

: Use a slightly faster travel speed and adjust the work angle to keep the puddle in place. 3. Vertical Position (3G & 3F)
