NUMERICAL ANALYSIS OF THE DIMENSIONS OF SPACERS FOR LASER WELDING OF PLATES OF POROUS METALS

A mathematical model of nonstationary processes of laser welding of porous metals with the use of a spacer placed between the ends of the plates to be joined has been developed. The infl uence of the dimensions of a spacer from nonporous metal on the quality of the produced joints and the morphology of the weld has been investigated. Dimensions of the spacers to obtain surface joints with the bead or fl ush-mounted with the welded plates have been determined numerically. Characteristics of the joints of porous titanium and steel plates that have been calculated using metal spacers, are in satisfactory agreement with the results of conducted physical experiments. This confi rms the adequacy and reliability of the proposed model.
