Pipe Welding Process 

   The LoneStar automatic welding system is designed for onshore and offshore pipeline construction. The system is based on an orbital welding principle.

      The LoneStar automatic welding system is part of the process involved in completing a qualified weld. The process has three main components.

1. The first part involves Dyna Torque's pipe facing equipment producing the required compound narrow bevel at the end of each pipe. Dyna Torque's pipe facing machines cover a wide range of pipe diameters from 6" to 44" providing precise and consistent bevels. Precise and consistent bevels are essential to the automatic welding process. Dyna Torque's pipe facing machines are self-contained, mobile, and easy to set-up.

2. The second part involves internal line-up clamps that allow perfect alignment of the two joints of pipes in preparation for the automatic welding process.

3. The third part involves the LoneStar automated welding system performing a welding joint of two pipes. The LoneStar automatic welding system is capable of welding pipe sizes ranging from 4" to over 60" in diameter with wall thickness in excess of 2 inches.
