由于电弧光，热影响等多方面因素的干扰，获取的熔池图像中总是存在着大量的噪声，因此图像预处理是熔池信息获取过程中必不可少的步骤。

Due to the interference such as arc light , heat and other influence factors , the images captured by CCD always contain a lot of noise , therefore , image pre-processing is an essential step in the acquisition process of weld pool information .

另外电磁铁是个大电感负载，当直流接触器接通和断开的时候，电感反电势非常大，很容易产生电弧光，烧坏直流接触器，因而故障率非常高，维修工作量很大。

At the other hand , electromagnet is a big inductance load , when DC contactor is on or off , electricity arc is easy to happen and burnout the contactor . So the fault rate is very high and it needs much repairing work .
