Using the welding does not happen in a virtual welding phenomenon, and 

Can achieve a multipoint welding, can need not consider the operating 

Skills of personnel, to ensure the quality of welding. And 

Temperature, can live in the present, to ensure the welding quality, 

Especially suitable for high precision welding of high-end products. 

Welding head classification: 
1. Resistance Welding Heads 
2. Spot Welding Heads, 
3. Butt Welding Head, 
4. Hot Bar Reflow Soldering Heads 
5. Ultrasonic Welding Machine Welding Head 
We can according to customers required to provide all kinds of welding machine welding head. 

The principle of spot welding head: 
When the current moment, will produce electric spark in the electrode tips, and insulating paint part of the contact with the electrode tip was burnt, other insulating varnish to flinch at both ends, Then metal wire is bare. 

Due to the continuing effect of the welding pressure, drives a large amount of current to flow into the bare metal wire and metal base, electrical energy is converted into heat energy, succeed except paint and welding are in the same pulse. 

The design of spot welding head 
To ensure that the welding process is stable and reliable, ensure the service life to spot welding head. 

Because different welding materials, solder joint is not the same, the 
Welding energy is different, the required welding head design is different, General welding head is divided into three parts, they are electrical parts, transition sections parts and discharge parts. 

Note: Document prices and pictures are for reference only, We will according to customers drawings or samples of spot welding head for quotation.
