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. Problems in the use of positioner electrode
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.
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
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.
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.
