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 DAurlio e 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 thermo-physical properties of material into account, but only refers 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 Ti4Al4V alloy, greater than the ones observed for other metals and alloys (Stainless Steels, Al and its alloys).
