Investigation of dissimilar metal welds by energy-resolved neutron imaging
A nondestructive study of the internal structure and compositional gradient of dissimilar metal-alloy welds through energy-resolved neutron imaging is described in this paper. The ability of neutrons to penetrate thick metal objects (up to several cm) provides a unique possibility to examine samples which are opaque to other conventional techniques. The presence of Bragg edges in the measured n...

متن کاملEffects of Microstructure and Bond Quality on the Ultrasonic Evaluation of Dissimilar Metal Friction Welds
During the last several years we have been investigating ultrasonic techniques for evaluating the quality of solid state weld interfaces [1 ,2]. Promising results have been obtained on a variety of different solid state welds by extracting features from the ultrasonic waveforms and applying pattern recognition algorithms to separate acceptable from unacceptable welds. In general, the primary di...
متن کاملA Methodology for Screening Candidate Dissimilar Metal Welds for Repair or Replacement
Dissimilar Metal Welds are required in high temperature sections of boiler reheater and superheater tubing to join low alloy steel tubing to the finishing stainless tubing. The intrinsic difference in the coefficients of expansion cause high stresses to develop at the relatively weak ferritic/weld interface. The power generation industry began to experience failures of type 309 stainless steel ...
