The secret of welding heads long life?

For welding head occupation, the length of application time has always been the core index to measure the quality of welding head. It is also a direction that many welding head have not explored for many years to study the welding head which is easy to use and can be used normally for a long time. At present, the mature scheme has always been to change the density and uniformity of the plating layer as much as possible under the condition of keeping the thickness of the plating layer unchanged. In this way, the stability and good composition of electroplating solution are the first step. At present, through the increase of trace components, such as the participation of nano-additives, the plating solution can be improved. This step is a great test of technical strength, and always after numerous tests, an excellent increase ratio was obtained at that time.

   The second step is to find the thickness and temperature of the coating and the golden section point. The alloy coating is thick, and the corrosion resistance will be prolonged, but its side effect is that the heat conduction will be weak. Therefore, how to balance the two is to make the coating as thick as possible without affecting the heat transfer speed. Under the premise of pursuing environmental protection, there is another kind of test being conducted, that is, welding high-purity alloy iron and copper together by using welding technology, the working part is made of alloy iron, and the back-end heat conduction still uses the good function of copper. The difference is that the former uses copper-based outer coating plating layer, while the latter is divided into two parts. The latter definitely has great advantages in corrosion resistance, and its limitations are obvious in heat energy transmission. Whether it can get a good habit under the soldering conditions with slightly higher temperature precision needs to be improved.
