Welding Cell – Broken Fastener Extraction


Many components are assembled with fasteners such as studs or bolts.  Over time, the fastener can “seize” into the higher value iron or aluminum mating part. When disassembly for remanufacturing is attempted, the seized fasteners can then “break off below the mating part surface”.  Due to this there are many cases where the higher value component is scrapped because the lower value component could not be extracted from it.


When the fastener size is ≤ 6 mm, and it is broken below the surface of the mating part, traditional methods of extraction are not very capable.


To solve this problem, Lifecycle Specialties created a welding process that is ~98% successful.  This type of approach can be applied to many other challenging components with broken fasteners.
