Paper Abstract

Experimental data of CO2 laser welding of the Ti6Al4V alloy have been studied in terms of efficiency. In particular a method, suggested some years ago, by Daurelio and Ludovico (DA.LU method), has been utilized. Contrary to what other researchers (Swift-Hook and Gick, Shuocker and other ones) assert, this one, as it is common knowledge, doesn't take the thermophysical properties of material into account, but only referst to process parameters (power, welding speed) and morphological characteristics (melted area and volume). The obtained results showed high values of the efficiency for the CO2 laser welding of Ti6Al4V alloy, greater than the ones observed for other metals and alloys (AlSI304, Al and its alloys).
