ESI2R Electrodes for Joule soldering

Principle:

Electric resistance welding, also called Joule effect welding, is a technique that replaces traditional soldering with a soldering iron. Its advantage is that it provides instant localized heat. The principle is to pass a powerful current at very low voltage through a contact resistance at the point of application. The law which explains this phenomenon is the Joule effect: W = RI² t

Use and advantages:

The welding operation consists of pinching the parts to be assembled and adding a tin alloy. As soon as the pedal is engaged, the temperature instantly rises to the desired temperature (maximum 1100 ° C).

• Better heat distribution (= better weld distribution)
• No component overheating (= instantaneous welding up to 1100 ° c) and therefore reduces thermal damage
• Flameless process
• Speed ​​of execution
• The pliers holds the assembly and leaves one hand free for welding
• No keeping a heating tool on standby
• Allows access to restricted areas
• Reduces energy consumption compared to a traditional heating tool
• Low maintenance and upkeep: the electrodes last longer than soldering iron tips and do not require tinning

Applications :

Connector soldering on semi-rigid
Coaxial connector center contact solder
Welding of several strands at the same time
Soldering of multi-pin connectors
Soldering sensitive connections
Welding high frequency cables
Butt splicing of copper strips
Fast welding of pre-tinned pellets
