Tungsten Copper Spot Welding Anode

Classification

There are many kinds of spot welding heads, including touch and micro spot welding heads. The welding head is divided into upper and lower parts, and the welded object is located in the middle of the upper and lower parts when welding. The current passes through the welded object and generates heat on the welded object. Sometimes the heat is generated mainly through the contact surface of the welded object and the welding head, which mainly depends on the resistance of which part is in the current loop. In a current loop, where the resistance is high, the heat is generated mainly in that area. Therefore, in contact welding, the resistance of the welding head is very important. Micro-spot welding head Micro-spot welding head is the welding head corresponding to the micro-electronic spot welding machine, its characteristics are mainly that the welding head and the welding machine have formed a loop, and the current through this loop, mainly generates heat at the tip of the welding head actively heating, but the welded object does not actively heating, the welding head contact the welded thing, instantly transfer heat to the welded object. To melt the soldered thing and weld it to another soldered thing in contact

Spot welding head selection

1. Firstly, select spot welding head materials and spot welding head types according to the melting points of welding wire materials and pad materials.

2. Select the contact area between the discharge part of the spot welding head and the weldment according to the solder joint requirements. Large welding wire requires a large contact area.

3. Select the shape of the discharge part according to the welding wire material and welding material.

Note the use of spot welding head

1. Can not air welding: air welding is not in contact with any metal discharge operation. The spot welding head will produce a high temperature of thousands of degrees when discharging. If there is no contact with any metal body, the spot welding head will stay at a high temperature for a long time, because the air contact is easy to cause oxidation, resulting in a black oxide layer. Thus reduce the service life of the welding head and reduce the welding effect.

2. Avoid sticking conductive foreign bodies in the cavity of the discharge part of the spot welding head. If sticking conductive foreign bodies, the welding effect will decrease.

3. Avoid short continuous operations.

Maintenance of spot welding head

1. If the spot welding head is black or oxidized seriously, it should be polished with fine sandpaper to remove the oxide layer.

Application and classification of spot welding heads

Spot welding head is used in various welding equipment. Including electronic spot welding machine, touch welding machine, hot press, ultrasonic welding machine, and other equipment

Our Advantages

Our company's independent production of embedded resistance welding electrode, also known as the combined electrode, the selection of high-quality tungsten alloy as the extreme electrical part, the internal structure is dense; The rod is made of red copper or chrome-zirconium copper to maintain the characteristics of high conductivity and high heat dissipation. Therefore, the selected materials have stable conductivity and heat resistance. Unlike the traditional brazing process, we use unique back casting technology, a non-destructive combination of tungsten and copper, so that the joint has no holes, gaps, and high connection strength. In addition, the extreme machining precision is high, the finish is below Ra0.8, and the electrode joint is firm. At the same time, we will customize welding electrodes of various specifications, prices, and technology for your choice according to your product usage scenario and specific needs, and we can also customize small batch production according to your drawings
