Series of Coils were introduced for Pipeline
Pre-Weld Demagnetization. If
pipe ends are magnetized when being lined up, welders will experience
Arc Blow (or Arc Bending), which more often than not, will lead
to weld defects.

The WDV-PD Series of Coils are specifically configured for Demagnetization of Pipe ends. These Demagnetization Coils are built with Western's exclusive PD
Centralizer, to position the Coil in the Centroid and
at the End of the pipe. Without the PD Centralizer, the powerful
Coil would jump towards the center of the pipe and would unevenly
demagnetize the end of the pipe.
To get an understanding of our Larger Coils, there are documents throughout this section that illustrate their size and capabilities. The documents
in this section of our web site will introduce
you to the design and use of WDV-PD Series Coils for performing
Reversing/Decaying DC Demagnetization.
