Treatment of welding joint problem: burning copper nozzle

原因分析：

  焊接过程中，有热量扩散到铜嘴致使损坏，处理过程应首先分析热量来源，镜片散光，红光偏还是外部材料导热

Cause analysis:

During the welding process, heat diffuses to the copper nozzle, causing damage. In the treatment process, we should first analyze the heat source, lens astigmatism, red light bias or external material heat conduction.

解决方案：

在处理前应确保

①红光居中（偏光会致使光打在通嘴上）

②合适的扫描宽度（一般在5之内，通常设置为3）

③焦点0焦（刻度管为0即可）

1.首先远距离对地出光，看一下铜嘴发不发烫，如果不发烫的话，说明镜片没有问题，没有出现散光，发热的话需要更换损坏的镜片

2.在以上正常的情况下焊接如果发烫，说明是焊接时材料导热，在实际使用过程中，外角铜嘴比内角更容易损坏，可以采用紫铜铜嘴

3.焊接手法也影响发烫，尽量焊接头与材质处于45°∠焊接

4.铝板等高反材料亦会造成铜嘴发烫，这个属于不可控的

Solution:

Before handling, ensure that

①red light in the middle (polarization will make light hit the mouth)

② Appropriate scanning width (generally within 5, usually set to 3)

③ The focus is 0 (the calibration tube is 0).

1. First, shine light from the ground at a distance to see if the copper nozzle is hot. If it is not hot, it means that there is no problem with the lens, and there is no astigmatism. If it is hot, it is necessary to replace the damaged lens.

2. If the welding is hot under the above normal conditions, it means that the material conducts heat during welding. In actual use, the outer corner copper nozzle is more likely to be damaged than the inner corner, so the copper nozzle can be used.

3. The welding technique also affects the burning. Try to weld the welding head with the material at 45 ∠.

4. High-reflectivity materials such as aluminum plate can also cause the copper nozzle to be hot, which is uncontrollable.
