Welding positioner is widely used in some factories. Its efficiency is relatively high and the effect of welding is relatively good. There are many forms of positioners, including arm type, seat type and double seat positioners. There is a certain gap in their use. They can be selected according to specific needs. Although their styles are different, they will use welding rods in their operation. What are the problems of welding rod in use? How to save energy in production? Now let's take a look.

1、變位機焊條使用中的問題

1. Problems in the use of positioner electrode

焊條是生產(chǎn)中使用較多的焊接材料，通常，焊條熔化到一定長度就得丟棄，另換焊條。丟棄焊條的長度越短，焊條利用率越高，電能和材料浪費就越少。無疑，合理使用焊條，縮短焊條丟棄長度，可以節(jié)約電能和材料。

Electrode is a welding material used more in production. Generally, when the electrode melts to a certain length, it must be discarded and replaced. The shorter the length of discarded electrode, the higher the utilization rate of electrode, and the less waste of electric energy and materials. Undoubtedly, reasonable use of welding rods and shortening the discard length of welding rods can save electric energy and materials.

焊接中，焊工常采用比正常值大的電流來提高焊條的焊接速度，由于焊接電流過大，產(chǎn)生的電阻熱急劇增加，電阻熱的積累就會使焊條藥皮發(fā)紅、開裂22k甚脫落，焊條未用到正常長度就得丟棄，同時過大電流焊接產(chǎn)生的灼熱也使勞動條件惡化，這種方法是以電能和材料的浪費為代價的。但從另一方面看，電阻熱對焊條有預熱作用。

In welding, welders often use a current higher than the normal value to improve the welding speed of the electrode. Due to the excessive welding current, the resistance heat generated increases sharply. The accumulation of resistance heat will make the electrode coating red, crack 22K or even fall off. The electrode must be discarded without using the normal length. At the same time, the burning heat generated by excessive current welding also worsens the working conditions, This method is at the cost of waste of electric energy and materials. On the other hand, resistance heat has preheating effect on the electrode.

2、變位機焊條的方法

2. Energy saving method of positioner electrode

焊接變位機在焊接開始時，用大電流焊接，利用所產(chǎn)生的電阻熱充分預熱焊條，焊條熔化到一定長度時把大電流換到較小電流繼續(xù)焊接，可使焊條的焊接速度較高，焊條丟棄長度短。都是可以有著不同的連接方式的，主要取決自己熟悉哪種方式的，這些都是與生活中或者是平時的運用有著相同的運用關系的，也是對它采用著不同的方法去進行的，這樣會擁有著不同的特色與我們實際生活或者緊密相連的運用之處的。

At the beginning of welding, the welding positioner uses high current for welding, and uses the generated resistance heat to fully preheat the electrode. When the electrode melts to a certain length, change the high current to a small current to continue welding, which can make the welding speed of the electrode higher and the discard length of the electrode shorter. They can have different connection modes, which mainly depends on which mode they are familiar with. These have the same application relationship with life or ordinary application, and they also use different methods to carry out it. In this way, they will have different characteristics and applications closely connected with our actual life or our daily life.

以上就是焊接變位機焊條的一些相關知識，焊條的使用在進行焊接時發(fā)揮了較大的作用，存在有較大的優(yōu)勢，能夠便于后期的焊接步驟正常進行。合理使用焊條也能在一定程度上做到，節(jié)省材料，從而可以產(chǎn)生一定的社會效益。

The above is some relevant knowledge of welding rod of welding positioner. The use of welding rod plays a great role in welding and has great advantages, which can facilitate the normal welding steps in the later stage. Reasonable use of welding rods can also save energy and materials to a certain extent, which can produce certain social benefits.
