Step four (Metalock Advantages)

Some advantages of the repair by the Metalock method are:

  • Work can be, and usually is, done on site, with usually a very great saving in time and dismantling.
  • Maintains alignment and original surfaces.
  • Dampens and absorbs compression stresses and spreads tensile strains.
  • Provides a good expansion joint on such jobs as cylinder liners.
  • Distributes the load away from fatigue points.
  • Maintains relieved condition of inherent internal stresses where these were the cause of the fracture, or partial cause.
  • Provides a low co-efficient of expansion in the relation to the repaired metal.
  • The repair being completely cold does not require the application of hear which could, and often does, introduce fresh stresses.
