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、变位机焊条使用中的问题

1. Problems in the use of positioner electrode

焊条是生产中使用较多的焊接材料，通常，焊条熔化到一定长度就得丢弃，另换焊条。丢弃焊条的长度越短，焊条利用率越高，电能和材料浪费就越少。无疑，合理使用焊条，缩短焊条丢弃长度，可以节约电能和材料。

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电流来提高焊条的焊接速度，由于焊接电流过大，产生的电阻热急剧增加，电阻热的积累就会使焊条药皮发红、开裂22k甚脱落，焊条未用到正常长度就得丢弃，同时过大电流焊接产生的灼热也使劳动条件恶化，这种方法是以电能和材料的浪费为代价的。但从另一方面看，电阻热对焊条有预热作用。

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. Energy saving method of positioner electrode

焊接变位机在焊接开始时，用大电流焊接，利用所产生的电阻热充分预热焊条，焊条熔化到一定长度时把大电流换到较小电流继续焊接，可使焊条的焊接速度较高，焊条丢弃长度短。都是可以有着不同的连接方式的，主要取决自己熟悉哪种方式的，这些都是与生活中或者是平时的运用有着相同的运用关系的，也是对它采用着不同的方法去进行的，这样会拥有着不同的特色与我们实际生活或者紧密相连的运用之处的。

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.

以上就是焊接变位机焊条的一些相关知识，焊条的使用在进行焊接时发挥了较大的作用，存在有较大的优势，能够便于后期的焊接步骤正常进行。合理使用焊条也能在一定程度上做到，节省材料，从而可以产生一定的社会效益。

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.
