Silver Contact Welding process problems and solutions
1. The influence of welding current
Electric current has a greater influence on heat generation than both time and pressure. Therefore, in the Welded Contacts welding process, the current parameter output must be strictly controlled. If the Contact Welding welding current is too small, the nucleus cannot be formed or the size of the nucleus is small, and the Electrical Contact Welding welding joint strength is small; if the welding current is too large, the surface and back of the silver contact will be black and the indentation will be too deep.
2. The influence of welding time
In order to ensure the strength of the silver contact solder joints, the welding time and welding current can complement each other within a certain range. In order to obtain a certain strength of the Brazing Electrical Contacts, but also to ensure the beauty of the Brazed Electrical Contacts, high current and short time can be used.
3. The influence of electrode pressure
The electrode pressure has a significant effect on the total resistance between the two electrodes Welding Electrical Contacts. The electrode pressure is small and splashing is easy to occur. As the electrode pressure increases, the total resistance decreases. When the electrode pressure increases and the welding current remains the same, it cannot compensate for the decrease in heat generation caused by the decrease in total resistance. Therefore, the strength of the Electrical Contact Resistance Brazing decreases with the increase in welding pressure. The solution of Resistance welding Contacts is to increase the pressure At the same time, increase the welding current.
4. The influence of electrode shape and material properties
Since the contact area of the electrode determines the current density, the resistivity and thermal conductivity of the electrode material are related to the generation and loss of heat. Therefore, the shape and material of the electrode have a significant influence on the formation of the nugget. With the deformation and wear of the electrode tip, the contact area increases, and the strength of the Silver Contact Welding will decrease. Pay attention to the maintenance and repair of the electrode (spot welding head) during use. When soldering the Welded Electrical Contact, first consider the stickiness of the solder joints. It is recommended to use tungsten steel electrodes; the soldering contact points are also particularly important. The upper and lower electrodes must be kept flat, otherwise it is easy to cause indentation. If the welding efficiency is too fast, the electrode head is likely to cause heat accumulation. It is recommended that the electrode head be filled with cold water.
