Butt welding head It is divided into upper and lower parts. When welding, the object to be welded is located in the center of the upper and lower parts. The current passes through the object to be welded, and heat is generated on the object to be welded. Sometimes the heat is generated mainly through the object to be welded and the touch surface of the welding head. See which part of the current loop has greater resistance. In the current loop, if the resistance of that part is large, then the heat mainly occurs in that part. Therefore, in the butt welding, the resistance of the welding head is very important. Micro welding head The micro-spot welding head is the corresponding welding head of the micro-electronic spot welding machine. Its characteristic is that the welding head and the welding machine have formed a loop. The current passes through this loop, and the heat is generated at the upper end of the welding head. The welding object does not automatically heat up. The welding head touches the welding object and instantly transfers heat to the welding object, melting the welding object and welding it to another touching welding object.

According to different electronic components and different welding process requirements, we have provided various types of welding heads. Special spot welding head for electronic spot-welder. Plane, Bevel,V, round,etc. When welding, it has the characteristics of bright, reliable, stable welding spot, signal attenuation, etc. The welding head is superior in quality, long in service life, complete in various specifications and types, and can be customized according to customer samples. According to the different specifications of spot welding wire diameter and the shape requirements of spot welding, different types of welding heads are selected. Spot welding head is the key component of paint removal and welding of electronic spot-welder. The welding head can be processed into different shapes according to the thickness of the wire diameter of the welded enameled wire and the workpiece, and can be designed according to the customer’s requirements. Specific applications include: production and manufacture of various electronic components with small coil, such as high- frequency communication components, SMD Transformer, SMD inductor, micro Hom, inductive IC card, buzzer, receiver, speaker, earphone, antenna, microphone, XT-xxq, hands-free headset, oscillating motor, micro, micro motor, clock coil, module and other small coil electronic components can be welded on the joint welding, the same can also be welded metal wire, metal strip, metal sheet, solar cell, welding of outgoing line contacts such as telecommunication data lines.

Spot welding heads for common metals 1.Projection welding of low carbon steel Low- carbon steel projection welding is widely used. The following table shows the welding conditions of round and conical projection welding.
