Types of hot pressing welding heads

There are many types of welding head/tip, such as hot pressing strips and hot pressing tip used in pulse resistance welding. These welding heads are divided into different materials, such as stainless steel, copper, tungsten, molybdenum, titanium, diamond, and other materials. So it is common to use different materials for welding joints in different production processes.

Now we introduce a pulse resistance welding head made of tungsten material. Suitable for welding IC card coils, SMD 0603, 0402 miniature inductors, solar panels, battery packs, FPC cables, etc.

Resistance Welding is the traditional welding technology used for IC card coils, SMD 0603, 0402 miniature inductors, solar panels,battery pack manufacturing. This reliable technology has been around for years and requires relatively low investment levels. Resistance Welding is a relatively straightforward process – the operator simply pushes down the battery tab with a weld head, which is operated by a cable or footswitch, and starts the weld. 

Because one is physically touching the part, resistance welding offers the easiest process data management and monitoring. The equipment can easily measure the welding process, including electrical parameters like current, voltage, resistance, power and mechanical parameters like force, height and movement of electrodes during welding. 

The advantages of pulse resistance welding are closed loop feedback and easy to monitor weld process ,self-tooling and able to weld plated materials, The material thickness can be welded from 0.2 to 5mm, and the welding speed is fast, up to 1 second.
