Abstract
In the present work the influence of peak power of laser beam welding
were studied at voltage range from 330 to 430 V and peak power (0,64; 0,75;
0,87; 1,01; 1,15; 1,31) kW , and laser beam diameter is standard and duration 8
ms. The microstructure after welding was studied. It was concluded that there is
a variant in grain size and shape in the welded zone and pre-welded area. The
dimensions of welded zone was measured. From measuring data, it was
observed, that as increasing the peak power the width and depth of welding
increased.
