焊接頭問題處理:燒保護鏡(中英)

表現:

Manifestation:


  短時間內保護鏡損壞出現燒點,保護鏡出光面有點狀損壞點,呈現黑色或白色中黑點

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:


  由于工藝/手法/設置等影響,造成反渣導致損壞,極個別為激光器出光異常

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


解決方案

solution


  ①適當增大氣壓,通常情況下流量不低于15,壓力不低于4,建議使用氧氣的壓力表不低于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焊接時盡量焊接槍與板材呈現45°焊接,不要垂直

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


  ③設置參數盡量給予緩升緩降,如開/關氣延時200-500ms,開/關光功率20%,開/關光漸進時間200-300ms,如圖不可設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在焊接鋁材和鍍鋅板時,這種材質會比其他材質更容易損壞鏡片,應使用最小功率焊接。

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保護鏡的質量也決定了其使用的耐用度,建議使用原廠鏡片

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,鏡片的損耗會提高,這個是不可控的范圍

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


  ⑦當以上都無法處理時,可更換F200聚焦鏡+加長寬刻度管來減少飛濺(需額外采購)

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