[repack] — Position Welding Pipe

Position welds are subject to rigorous non-destructive testing (NDT), specifically Radiographic Testing (RT) or Ultrasonic Testing (UT). Common defects specific to position welding include:

In the 1G position, the pipe axis is horizontal, and the pipe is rotated. The welder remains stationary, depositing metal at the top (12 o'clock position). This mimics flat welding on a plate. It allows for high deposition rates and is the most efficient position for shop fabrication where rotators are available.

By following best practices and understanding the benefits and challenges of position welding pipe, welders can produce high-quality welds in a variety of applications.
