精密零件焊接的激光焊的主要優點是： The main advantages of laser welding for precision parts are:
(1) 精密零件焊接的激光可通過光導纖維、棱鏡等光學方法彎曲傳輸，適用于微型零部件及其它焊接方法難以達到的部位的焊接，還能通過透明材料進行焊接。
(1) the laser of the precision part welding can be flexed through optical fiber, prism and other optical methods. It is suitable for the welding of the parts which are difficult to reach by the micro parts and other welding methods, and can also be welded through the transparent material.
(2) 能量密度高，可實現高速焊接，熱影響區和焊接變形都很小，特別適用于熱敏感材料的焊接。
(2) high energy density, high speed welding, heat affected zone and welding distortion are all very small, especially suitable for welding of heat sensitive materials.
(3) 精密零件焊接的激光不受電磁場的影響，不產生X射線，無需真空保護，可以用于大型結構的焊接。
(3) the laser welding of precision parts is not affected by electromagnetic field. It does not produce X rays, and does not need vacuum protection. It can be used for welding large structures.
(4) 可直接焊接絕緣導體，而不必預先剝掉絕緣層；也能焊接物理性能差別較大的異種材料。
(4) the insulation conductor can be directly welded without having to strip the insulating layer in advance, and can also weld dissimilar materials with great physical properties.
