In the manufacturing of electronic components, the connection between copper wire and brass sheet is generally completed by soldering, which is cumbersome to operate and has poor soldering effect. At present, many of our customers choose to use Chuangde spot welding machines to complete welding. Of course, there are also many methods and precautions involved. Today, we will share them with you.
How to spot weld copper wire and copper sheet
1. Both purple copper wire and brass sheet have excellent electrical and thermal conductivity, so it is important to choose resistance welding equipment with stable and concentrated welding current. We recommend using a medium frequency inverter DC spot welding machine.
2. Copper wire welding and brass spot welding have similar welding parameters, both following high current and short-term welding methods. The current is too low to achieve the welding purpose. Over time, it can damage the strength of the material itself and even melt.
3. Copper wire and copper sheet spot welding, especially purple copper wire spot welding, must have stable welding pressure, good follow-up of the cylinder, and provide continuous and stable pressure to the workpiece during the welding process in order to form a good welding product.
4. The selection of electrode materials for welding purple copper wire and brass should not use electrodes made of purple copper or brass materials. Chromium zirconium copper is also not a very good choice. We recommend that you choose tungsten copper alloy materials with higher hardness and melting point for electrodes, so that copper wire welding can achieve good results.
5. The shape design of the electrode head needs to be tailored according to the actual needs of the product and the welding forming requirements.
6. For welding larger specifications of copper wire, multi pulse discharge welding should be selected to increase preheating current and tempering current, which is widely used in the forming welding of copper braided wire.
The welding of purple copper wire, copper braided wire, purple copper wire, and brass terminals is similar and almost identical. However, as long as we choose a suitable resistance spot welding machine and master the correct welding method, there is no problem in achieving good copper wire welding results.
