In the present work, a detailed study of the mechanical behaviour of materials with a composition typical of the fusion zone of AA6056 laser welds conducted with AA4047 filler wire, is presented.
In both cases the materials were melted in a furnace by using a graphite crucible covered with boron nitride, and subsequently cast in a boron nitride coated stainless steel mould and air-cooled.

The shape of the heat-spot on the material has been treated as constant for a long time, regardless of the speed of the material to be processed.
In fact, on the surface of the material the light and the material mutually act on each other, so the shape of the heat-spot which appears on the surface many vary depending on the processing speed.
Material: SPHC Hot-rolled plate metal with black scale Material: ZAM Highly corrosion-resistant hot-dip coated steel.
Therefore no additional oxidation combustion reaction caused by heated active gas was reflected in calculations. 3.2 Theoretical analysis of high-speed metal foil cutting As the thickness of the foil was very thin and heat-spot was extremely small, the calculation model that a small heat-spot moved on the materials was used for metal foil cutting.
