How to choose a welding machine?

Depending on the battery product, connecting strip material and thickness, choosing the right welding machine is critical to ensuring the quality and performance of the battery. Below are recommendations for different situations, and the advantages and disadvantages of each type of welding machine:

1. Transistor welding machine:

Transistor welding machines are suitable for cases where the material of the connecting strip has good electrical conductivity, such as nickel and nickel plated strips. This type of machine heats the welding rod and the connecting strip to a certain temperature by means of resistance heating, and then applies a certain pressure to weld them together.WechatIMG358

Advantages: Suitable for materials with good electrical conductivity, such as nickel. High welding stability, suitable for mass production.

Disadvantages: Not applicable to materials with poor electrical conductivity, such as aluminum. May cause some thermal effects on the connecting strip.

2. High frequency machine:

High-frequency machine utilizes high-frequency current to produce resistance heating between the connecting workpieces, suitable for materials with poor conductivity, such as hardware.

Advantages: Suitable for materials with poor electrical conductivity. The discharge time is long enough.

Disadvantages: not applicable to all materials, may need to debug the welding parameters to get the best results.

3. laser welding machine:

Laser welding machines utilize a high-energy laser beam to generate instantaneous high temperatures on the connecting pieces, melting and joining them together. Laser welding is suitable for a wide range of materials, including different types of metal connecting workpieces.

Advantages: Suitable for a wide range of materials, including materials with poor electrical conductivity, such as aluminum. High welding precision and low heat impact allow for tiny welds.

Disadvantages: Higher equipment costs. Higher requirements for operators, suitable for fine welding.

Depending on the situation, different types of welding machines are recommended:

Materials with good conductivity (e.g. nickel, nickelplated): Transistor welding machines are available to ensure welding stability and mass production requirements.

Hardware: High-frequency machines for fast welding speeds.

It should be noted that, in addition to the conductivity of the material, the thickness of the connecting piece should also be considered. For example, the welding of lithium batteries and nickel pieces, it is highly recommended to use our transistor welding machine - PDC10000A, which can weld a wide range of discharge time is very fast, the welding time can reach the level of microseconds, higher precision, less damage to the battery, and the defective rate can be controlled at three ten thousandths.

In addition, the operator’s skills and experience also have an important impact on the welding results. By reasonably selecting the machine, optimizing the welding parameters, and ensuring that the operation is standardized, high-quality battery connections can be achieved, guaranteeing the performance and reliability of the battery components.

In conclusion, the product to be welded, the material and thickness of the connecting strip as well as the technical requirements of the welding will combine to influence your choice of the type of welding machine.
