The welding effect of 18650 lithium battery spot welding machine is affected by various factors, including the following main aspects:

1、 Welding parameter settings:

Current size: The welding current directly affects the melting condition and welding quality of the welded joint, and needs to be set reasonably according to parameters such as battery type and thickness.

Welding time: Welding time determines the input time of heat during the welding process, and being too long or too short can affect the quality of the welded joint.

Pressure level: Appropriate welding pressure helps ensure good contact of the welded joint, but excessive pressure may cause deformation or damage to the welded joint.

2、 Electrode design and materials:

Electrode shape: The shape of the electrode directly affects the shape and quality of the welded joint, and a suitable electrode shape needs to be designed according to specific welding requirements.

Electrode material: The electrode material should be selected with good conductivity, wear resistance, and heat resistance, such as pure copper or copper alloy, to ensure stability and durability during the welding process.

3、 Battery surface treatment:

Surface cleaning: Before welding, it is necessary to clean the surface of the battery to remove oil stains and oxides, in order to ensure good contact of the welding joint.

Surface coating: In some cases, a layer of welding agent or coating can be applied to the welding joint to improve the stability and corrosion resistance of the welding.

4、 Welding environment:

Temperature: The temperature of the welding environment can affect the working effect of the welding machine and the quality of the welded joint, and it needs to be maintained within a suitable temperature range.

Humidity: Excessive humidity may cause oxidation of welded joints, affecting welding quality.

5、 Operational techniques:

The technical level and experience of operators have a direct impact on the welding effect, and it is necessary to train and improve the welding skills of operators.

The welding position and posture can also affect the quality of the welded joint, and it is necessary to pay attention to the operating specifications and correct operating posture.

6、 Equipment maintenance:

The maintenance of welding machine equipment also directly affects the welding effect. It is necessary to regularly clean, lubricate, and maintain the equipment to ensure that it is in good working condition.

In summary, the welding effect of 18650 lithium battery spot welding machine is affected by various factors, and it is necessary to comprehensively consider and reasonably set welding parameters, maintain good operating techniques and equipment maintenance, in order to ensure the quality and stability of welding joints.
