Abstract
Peculiarities of laser welding of the 0.15 and 0.20 mm thick austenitic stainless steel sheets were studied. It was shown that at a certain power of the laser beam the experimentally measured width of the weld could be satisfactorily described by the model of a linearly moving source in a homogeneous approximation. Increase in power of the laser beam results in formation of a hole on the surface being welded, through which part of the beam power goes away, thus leading to violation of correlations with the model. Based on the peculiarities revealed, a procedure is proposed for determination of optimal welding parameters to provide the maximal effective efficiency of the process.
