This research work deals with the most commonly used titanium alloy, Ti6Al4V. Lap and butt laser welding processes were studied and tested by a CO2 laser system using two covering gases (He and Ar) with different welding covering gas nozzles, gas pressure and flow rates. A metallographic analysis of the cross-sections of welded specimens was carried out in order to measure the morphological characteristics of the welded joint, and micro-hardness and tensile tests were performed to complete the mechanical characterization.

Abstract

This research work deals with the most commonly used titanium alloy, Ti6Al4V. Lap and butt laser welding processes were studied and tested by a CO2 laser system using two covering gases (He and Ar) with different welding covering gas nozzles, gas pressure and flow rates. A metallographic analysis of the cross-sections of welded specimens was carried out in order to measure the morphological characteristics of the welded joint, and micro-hardness and tensile tests were performed to complete the mechanical characterization.
