Evaluation of mechanical properties of friction stir welded commercially pure aluminium
MATEC Web of Conferences, 2018 In this study, friction stir welding (FSW) of commercially pure aluminium is carried out. The main defects existing in this process are cavity, irregular material flow due to unsuitable selection of welding parameters.

Selection of cutting parameters for the machinability of Inconel 718 using Grey Relational Analysis
MATEC Web of Conferences, 2018 Inconel 718 is considered to be most difficult to machine superalloy because of its high shear strength, work hardening and precipitation hardening. Abrasive particles which are in microstructure have tendency have forming chip to be welded to tool and ...

Digital NDT (Non Destructive Testing)
IFAC Proceedings Volumes, 1995 Abstract The objective of this work was to improve the electronics of an NDT(disperse magnetic flux) equipment by means of real time digital processing of the signals coming from the field, thus increasing reliability, precision, accuracy and decreasing calibration times. An electronic defect simulator was built in order to obtain signals similar to

PV Defects Identification through a Synergistic Set of Non-Destructive Testing (NDT) Techniques [PDF]
Sensors, 2023 A synergistic set of NDT techniques, including I–V analysis, UVF imaging, IR thermography, and EL imaging, supports a diagnostics methodology developed in this work to qualitatively and quantitatively identify a wide range of PV defects. The methodology is based on (a) the deviation of the module electrical parameters at STC from their nominal values ...

Non destructive testing (NDT) with high Tc RF SQUIDs
Journal of Physics: Conference Series, 2008 A high Tc rf SQUID nondestructive evaluation (NDE) set-up has been realized to measure the eddy current induced field in different aluminum samples, under a weak AC and low frequency magnetic excitation. An efficient and simple analytic modeling method has been also developed for computing the magnetic field created by the induced eddy current in the ...
