The battery cannot be used at high temperatures. Typically, manufacturers use laser welding to solder lithium batteries, and the tabs can be soldered with a soldering iron. If it is aluminum tabs, you can use WEWELDING M51 welding wire with a soldering iron. low temperature of 179 degrees in conjunction with M51- When used with F flux, the success rate is very high.
The battery nickel sheet has good spot welding effect, lower internal resistance, anti-oxidation, corrosion resistance, longer battery discharge time and stronger battery spot welding. Mainly reflected in various lithium batteries, the main spot welding methods of output parts and connection parts are as follows: 1. Press the power switch of the spot welding machine from bHongda battery to the “on” position to turn on the power. 2. Confirm that all parameters of the battery spot welding equipment have been adjusted, and prepare related materials and tools according to the parameter setting table on the right. From the tools you can use: a double-headed spot welder, a file cutter, a pressing device, a hex wrench. When debugging the equipment parameters of the battery spot welding machine, it must be confirmed by quality engineering, and it can only be used if it meets the requirements. When spot welding 18650 lithium batteries, you should pay attention to the voltage of spot welding, and the voltage value should be within the quality inspection range.
