Abstract
Deep penetration weldings with a 2kW CO 2 laser were performed on different austenitic stainless steels in a wide range of thicknesses for two different assistant gases. The energy actually transferred to the samples to perform the welding process was calculated in terms of the LSM model for the different steels examined. Then, the trends of the efficiencies versus the thickness of the samples welded were plotted. These curves have a maximum which corresponds to an execution speed value which is approximately the same for all the different steels and is, moreover, equal to the heat propagation speed inside the material. Furthermore, a semi-empirical rule which takes into account both the thermophysical properties of the steel and the laser power is suggested for evaluating the trend of the weld width with respect to the process speed.
