激光焊 is a non-contact process which requires access to the weld zone from only one side of the parts being welded. The laser weld is formed as the intense laser light rapidly heats the material - typically calculated in milliseconds.
三 类激光焊接 可通过 激光焊: conduction, conduction/penetration and penetration or 'keyhole.' Conduction welds are performed at low energy, resulting in wide, shallow weld nuggets. Conduction/penetration welds utilize a medium energy density and result in a deeper weld nugget. Penetration or keyhole welds are resultant of direct energy delivery into the material being welded resulting in deep, narrow nuggets.
由于 激光焊 是一种非接触式的焊接/切割工艺，可焊接大量不同形状的接头，但各接合表面必须紧密接合。
Laser welders can join a wide range of steels, nickel alloys, titanium, aluminum, and copper. As with other joining technologies, some materials are difficult to laser weld unless they meet specific characteristics, namely, reflectivity, the effect of high thermal cycling, and the vaporization of volatile alloying elements.
