Optical fiber welding electrical great so important? 1, the electrode stick is a major component of the inside welding machine, plasma welding is through electrode stick to the end, but there are a lot of people don't know about electrode rod is belong to the consumable, must life need to be replaced, the next I will introduce our electrode rod exchange main sex, and some knowledge of life. 2, the first to know about the electrode stick aging process, the electrode stick with the naked eye observation is similar to the very tip of a needle, although its metal material is hard and there will be no external force wear and tear, but because of the need to bear high temperature for a long time discharge, so the starting discharge apex, inevitably gradually loss, of course it is an ideal state. Electrode great loss in the process of actual use as shown in the figure below, because of high energy heat discharge process in optical fiber glass ion diffusion, adsorption to the electrode bar apex, formed a conductive insulating material, in use for a period of time with the naked eye can be observed on the rod electrode these impurities. Insulating film production will make the arc to avoid the discharge, so the wastage of the original start from the top, there might be to start from the back, in the long term will intensify electrode bar apex of the wear rate, make its become very irregular. 3, that in this case, had triggered the tip of the two stable arc, it becomes unstable, on the welding machine may alarm ( Discharge the left or right) So that it can't provide the stable source of heat for the welding of the fiber, the splicing loss will not ideal after all. So the service life of electrode bar may not be as long as we fantasy, in case of the above situation, in order to guarantee the quality of welding, it is necessary to replace the new electrode rod. And choose the original electrode rod is very main, fake electrode stick is not capable of high temperature material, size is differ, such as abnormal, so not only electrode stick their life is very short, and because may form a discharge voltage instability, will bring the inside of the welding machine power device burden, or even damage of formation. 4, and of course the electrode wear under the influence of many external factors, such as air humidity, temperature and fiber material and so on, so the rod electrode life under different working conditions may differ a lot, although our manufacturer has suggested that the use of number, but still recommended users according to its actual use conditions to determine the frequency change. Then often discharge correction also helps to prolong the life of electrode bar and improve the quality of welding.
