精密零件焊接的激光焊的主要优点是： The main advantages of laser welding for precision parts are:

(1) 精密零件焊接的激光可通过光导纤维、棱镜等光学方法弯曲传输，适用于微型零部件及其它焊接方法难以达到的部位的焊接，还能井盖钢模具 U型槽模具 天津水处理设备 检查井钢模具 保定公司注册 u型槽模具 流水槽模具 通过透明材料进行焊接。

(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，可实现高速盖土网 防寒布 麻绳 油麻绳 麻刀 沥青麻绳 静压造型线 自动浇注机 铸铁拍门 钢制拍门 玻璃钢拍门焊接，热影响区和焊接变形都很小，特别适用于热敏感材料的焊接。

(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电磁场的影响，不产生X射线，无需真空保护，可以用于大型结构的焊接。

(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) 可直接焊接绝缘导体，而不必预先剥掉绝缘层；也能焊接物理性能差别较大的异种材料。

(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.
