Abstract
An alternate cleaning process to chemical process of Ti–3Al–2.5V tube surface by a pulsed fiber laser and welding of the laser-cleaned tubes with end fittings by Pulsed Gas Tungsten Arc Welding (GTAW-P) technique is reported in this paper. Results on surface morphology, hardness, chemical composition, metallography and X-ray radiography are presented for laser assisted cleaning and welding of Ti–3Al–2.5V alloy tubes. Welding of laser-cleaned samples show excellent weld quality.
