2G pipe welding!
In 2G pipe welding, the pipe is in a horizontal (flat) position, and the weld is made on the top of the pipe, with the welder working from the top side of the pipe.
Here are some key aspects of 2G pipe welding:
*Key Aspects*
- *Pipe position*: Horizontal (flat)
- *Weld location*: Top of the pipe (12 o'clock position)
- *Welder position*: Working from the top side of the pipe
*Challenges*
1. *Gravity*: Weld pool can sag or fall, affecting weld quality
2. *Visibility*: Welder must work with limited visibility, as the weld area is on top of the pipe
3. *Accessibility*: Welder must access the weld area from the top side of the pipe, which can be challenging
*Techniques*
1. *Use of welding fixtures*: Fixtures can help maintain pipe alignment and stability
2. *Welding with a push technique*: Pushing the weld pool can help control gravity and maintain weld quality
3. *Using a welding helmet with a shade*: A welding helmet with a shade can help protect the weld
