Mm 0.2 enameled wire and copper welding, with spot welder good. Better with laser welder. Now the parts are machined with micro spot welding machine. Pressure and current are not good control, welding quality is not good, not welding is not strong, it will break.
Ultrasonic wiring harness welding machine (lap welding) without accessories, welding speed, fastness, superior conductivity. Your line is thin, there may be such problems, if you like, we can help you proofing
Enameled wire is not good, if the copper sheet can be bent a hook, the enameled wire will be placed in the middle of the hook, and then welding with a common touch welding machine will be fine.
Resistance welding is suitable for processing materials with high resistivity. For copper, the resistivity is small, the heat consumption on the welder is large, and the efficiency is low. Small diameter solder joints can be brazed
