  • Electrofusion : a simple method of joining PE pipes

    2018-5-29u2002·u2002Electrofusion is a simple method of joining PE pipes in circumstances where butt fusion is not practicable, such as where valves, elbows, and tees must be added. Prefabricated fittings are used, incorporating an electrical heating coil which melts the plastic of both the fitting and the pipe, causing them to fuse together.

  • The FOA Reference For Fiber Optics - Fusion Splicing

    2020-4-3u2002·u2002Fusion Splicing Fusion splicing is the process of fusing or welding two fibers together usually by an electric arc. Fusion splicing is the most widely used method of splicing as it provides for the lowest loss and least reflectance, as well as providing the strongest and most reliable joint between two fibers.

This usually yields twice as many cells as needed for the fusion. X63s are thawed the week before the fusion, and are split out 1:2 each day until the day before the fusion (i.e. Monday through Wednesday) to keep in exponential

  • Lack of fusion in welded joints - NDT.net

    2006-8-15u2002·u2002A joint between the solid phase and the liquid one forms. It is like a brazed joint. This type of lack of fusion cannot be detected by non-destructive testing methods but with a microscopic inspection. A straight fusion line indicates that there may be the lack of fusion between the parent metal and the weld.
