In this experiment, the laser welding process is selected for welding AISI 304 stainless steel sheet, thickness 2 mm, 2, 2.5, 3 power kW and the frequency of the laser beam 4, 6, 8, heard and to measure the shape of the welding. To determine the relationship of power and frequency that affect the shape of the welding and comma structure. The trial found that, if the quantity of energy and increases in frequency increase tends to make the width and depth of the increased by welding and metal parts that are attached to the metal welds and flesh melting while welding, but received the influence of heating that occurs to Equiaxed Dendrite structure, which resembles a tiny bit.
