焊接头问题处理：烧保护镜（中英）

表现：

Manifestation:

  短时间内保护镜损坏出现烧点，保护镜出光面有点状损坏点，呈现黑色或白色中黑点

In a short period of time, the protective mirror is damaged and the burning point appears, and the protective mirror is a little damaged point on the glossy surface, showing black or white medium black spots

原因分析：

Cause analysis:

  由于工艺/手法/设置等影响，造成反渣导致损坏，极个别为激光器出光异常

Due to the influence of process/technique/setting, the anti-slag is damaged, and the laser light is abnormal

解决方案

solution

  ①适当增大气压，通常情况下流量不低于15，压力不低于4，建议使用氧气的压力表不低于2公斤

Appropriately increase the air pressure, usually the flow rate is not less than 15, the pressure is not less than 4, it is recommended to use the pressure gauge of oxygen is not less than 2 kg

  ②焊接时尽量焊接枪与板材呈现45°焊接，不要垂直

When welding, try to weld the gun and the plate at 45°, not vertically

  ③设置参数尽量给予缓升缓降，如开/关气延时200-500ms，开/关光功率20%，开/关光渐进时间200-300ms，如图不可设0

Set the parameters as much as possible to give slow rise and fall, such as on/off gas delay 200-500ms, on/off optical power 20%, on/off light progressive time 200-300ms, as shown in the figure can not set 0

  ④在焊接铝材和镀锌板时，这种材质会比其他材质更容易损坏镜片，应使用最小功率焊接。

When welding aluminum and galvanized sheet, this material will be more likely to damage the lens than other materials, and the minimum power welding should be used.

  ⑤保护镜的质量也决定了其使用的耐用度，建议使用原厂镜片

The quality of the protective lens also determines the durability of its use, and it is recommended to use original lenses

  ⑥高功率下，相比于低功率，镜片的损耗会提高，这个是不可控的范围

At high power, the loss of the lens will increase compared to low power, which is an uncontrollable range

  ⑦当以上都无法处理时，可更换F200聚焦镜+加长宽刻度管来减少飞溅（需额外采购）

When none of the above can be handled, F200 focusing lens + extended wide scale tube can be replaced to reduce splashing (additional purchase required)
