Industry updates: Laser beam build-up welding restores damaged components
Abstract
Turbine components are restored to service condition by means of laser-beam deposition welding. The first step in the repair of a damaged composite using this technique is to conduct a three-dimensional scan. A computer program then compares the dimensions of the part with its original measurements and computes what is missing. An IWS software system guides the path of the laser as it welds on titanium-alloy powder and reconstructs the damaged area with layers of metallic beads. The entire process chain is a closed cycle and runs automatically from data collection followed by welding to finish-machining.
