The electrode rod is an important component welding machine inside, discharge welding is done by electrode rod, but many people do not understand is a consumable electrode rod is, to a certain life needs to be replaced, then I tell you about the electrode as well as some knowledge of the importance of life-related rod exchange.

 

The importance of the exchange of the electrode rod and life

 

First, let's look at the aging process of the electrode rod electrode rod with the naked eye like a very sharp needle, although it is very hard metal material wear and does not have force, but take a long time due to the discharge withstand high temperatures, so from discharge start apex, the loss will inevitably slow, of course, this is an ideal state.

 

, The discharge electrode during a period of time due to the thermal energy of the glass fiber itself resulting ion diffusion, adsorption to the electrode rod tip, forming a non-conductive insulating impurities, using the loss of the actual process of using multi-electrode rod as shown in FIG. the rod can be observed with the naked eye these impurities.

 

The importance of the exchange of the electrode rod and life

 

Insulating film produced will make an arc away from its discharge, so the loss of the original starting from the top, there is likely to start from the rear into the long run will increase the wear rate of the electrode rod tip, it becomes quite irregular .

 

If that happens, there are two stable tip of the original trigger arc, it will become very unstable, there may be on the welding machine will alarm (discharge through the left or too right), so it can not provide a stable source of fiber splicing that the final splice loss is not ideal.

 

The importance of the exchange of the electrode rod and life

 

So the life of the electrode rod may not be so long as we imagine, in the above situation, when, in order to ensure the quality of welding must be replaced with new electrode rod.

 

And select the original electrode rod is also very important, the presence of counterfeit electrode rod material is not high temperature, size and other unusual sizes, so not only the life of the electrode rod itself will be very short, and due to the possible instability caused by the discharge voltage situation, give power devices inside the welding machine burden, and even cause damage.

 

Of course, the electrode rod wear by many external factors, such as air humidity, temperature, and optical materials and so on, so the life of the electrode rod different working environments may vary a lot, although we have recommended that the number of manufacturers use, but it is recommended users according to their actual usage to determine the frequency of replacement. Then often discharged correction also help extend the life of the electrode rod and improve the quality of welding.
