A fundamental process to produce wound components and welding copper wire to the terminal.
Marsilli has thirty years of experience using this process.
Over the years technology has evolved and much of it has been developed internally thus achieving optimum results both for performance and traceability.
Today the choice of the technology to use is given by taking many parameters into consideration such as the material to use, the result to reach in terms of mechanical resistance, hydraulics and the shock the product undergoes during the process.
This process is so important that at Marsilli today there are people with long standing experience who deal specifically with welding and the lab tests needed to define the most appropriate method to subsequently apply in production.

Some of our Wire Connection Technologies


The Terminal and wire plunge in hot solder for a few seconds. The solder burns wire insulation and covers the copper wire making the solder joint.
Soldering technology works for solderable wire at a temperature around 420 °C, that in presence of lead-free solder goes up to 440 – 450 °C, adding some concerns to maintainability and durability of materials.

Induction Soldering
Hot Tip Soldering
Laser Soldering
Resistance Welding
Spot welding is a resistance welding method used to join two or more overlapping metal parts.
Two shaped electrodes used to concentrate the welding current into a small "spot" and to simultaneously hold the parts together.
Thermocompression Bonding
Arc Welding
Stripping technology is used to remove the insulating enamel from the wire, so that it can be welded.
Laser Welding
Insulation displacement
Ultrasonic metal welding
