Case History---Peer-Reviewed

Abstract

Laser welded T-shaped steel joints were received in debris form. The debris were recovered from the crashed component. Different metallurgical analysis was made on these debris to reach the root cause of the failure. In this regard, optical microscope and scanning electron microscope were utilized for the confirmation of different observations. Huge deposits of oxidation products were observed on the thick part (i.e., plate) of the T-shaped joint. For the confirmation of these products a set of simulated experiments were also performed.
