During the process of electrical resistance soldering, the parts to be joined are pressed together with tongs or welding heads, and by supplying electricity, the solder is melted electrically at the contact points between the components. After heating the solder, the electricity supply is terminated. The solder fills small gaps, levels uneven places and finally solidifies.
Resistance soldering is usually used for hard soldering or high-temperature soldering over 900°C.
- Precise dosing of the supplied energy possible
- Adjacent areas around the solder joint are insignificantly affected
