Bridge Blauwverlaat

Reducing harmful residual tensile stresses arises during weld repair of cracks in the Deck plate of the ballast box of a bascule bridge. Cracks are initiated near stiffener plates at the inside of the box but there is no access to this location during repair.
Applying UIT on every single weld layer of the repair weld and introduce compressive stresses.
  • Preventing cracks caused by overload in the root layer because of immediately stress reduction.
  • No harmful residual tensile stresses are present after welding is finished, this results in a construction that is able to carry a higher load during use.
