First, the principle of wave soldering

2023-03-20

Wave soldering is a kind of melting welding. The principle is to generate a strong arc through the electrode, heat the metal material to the melting point, and add the molten welding material (welding wire) between the metal, so that it is cooled in the molten state, and finally form a strong welding iron. The essence of wave crest welding is a kind of enhanced cut arc welding, that is, when the metal is melted, the material is stripped and cleaned through the arc force, so as to achieve high quality weld effect.Plug-in Machine

Two, wave welding process

The wave crest welding process mainly includes the following links:SMT Machine

1. Workpiece preparation: Before Wave Soldering, the welding parts need to be thoroughly cleaned and treated to ensure that there are no impurities and stains in the welding parts.

2. Contact between electrode head and workpiece: After the contact of welding site, electrode head acts as the controller of welding point and moves the welding point to the required position.

3. Electrode head charging: The process of electrode head charging is an important part of the generation of strong arc, the arc generated by it can be heated to the welding part to the melting point in a short time, so as to form a uniform molten pool.

4. Add the welding wire: after the welding wire is melted, the welding wire is introduced into the welding pool for cooling through the arc, so as to make the weld become strong and achieve high quality weld effect.

5. Cooling: After the welding, it is necessary to carry out cooling treatment to ensure that the welding iron parts will not occur deformation and other problems.

Three, the advantages and disadvantages of wave welding

Step 1: Advantages

(1) Fast speed: wave welding has high working efficiency and production speed, thus saving time and cost.

(2) Beautiful weld: Because wave welding can realize continuous heating and cooling of welded iron parts, the weld is very tight and strong, and its surface is smooth and smooth, high aesthetic degree.

(3) Wide range of application: wave welding is suitable for a variety of materials, including stainless steel, aluminum alloy, carbon steel and so on.

(4) High degree of automation: the automation degree of wave crest welding is very high, can realize automatic welding, robot welding and other modes of operation, so as to reduce the interference of human factors, improve the production efficiency.

Step 2: Weaknesses

(1) The surface of plasma is rough: due to the different working conditions of the electrode on different materials, the surface of plasma is difficult to reach the ideal state, which will affect the aesthetics to a certain extent.

(2) Limited application: wave welding needs to clean and treat the surface of the material, so its application range is limited to a certain extent.
