How to prevent the wave soldering false soldering?

Wave soldering is a common welding defect, which is mainly caused by improper setting of welding parameters during the welding process or faulty welding equipment. In order to prevent wave soldering, a series of effective measures must be taken to improve welding quality and productivity. Here are some ways to prevent wave soldering false soldering:

1. Quality control: First, quality control should be strengthened to ensure that the welding process complies with standards and specifications. The welding parameters and equipment should be strictly controlled to ensure that each link meets the requirements to avoid problems.

2. Training of technicians: In addition, welding process technicians should be trained to understand the reasons why false welding is likely to occur in the welding process and to master effective preventive measures. Training should include welding principles, welding parameter settings, equipment maintenance and other content.

3. Uniform heating: In the wave soldering, to ensure that the weldment is uniformly heated. If the temperature of the weldment is not uniform, it will make the welding solder can not be melted, resulting in false soldering. Therefore, when carrying out wave soldering, pay attention to control the preheating time and temperature to ensure that the weldment is soldered at the appropriate temperature.

4. Inspection of welding equipment: Welding equipment should be inspected regularly to ensure that it is operating properly. Sensors, controllers and other components in the welding equipment should be regularly maintained and serviced to ensure their accuracy and stability. If the equipment is found to be faulty, it should be repaired or replaced in time.

5. Check the welding parameters: the welding parameters are regularly checked and adjusted. Too high or too low welding parameters will lead to a decline in welding quality, and it is easy to appear defects such as false welding. Therefore, when wave soldering, make sure that the welding parameters are set accurately to ensure the quality of welding.

6. Control of welding speed: Control of welding speed is the key to preventing false welding. If the welding speed is too fast, it will lead to the solder can not be completely melted, thus generating false soldering. Therefore, in the wave soldering, according to the welding requirements and welding materials to control the welding speed, to ensure that the solder can be completely melted, wetting the surface of the weldment.

7. Design a reasonable welding structure: In designing the welding structure, we should consider the welding direction, thickness of the weldment, material and other factors to design a reasonable welding process. Reasonable welding structure can reduce welding stress and deformation, reduce the incidence of false welding.

8. Quality Inspection: Welding quality inspection should be strengthened, and the welded joints should be comprehensively inspected and evaluated. Timely detection of problems and take effective measures to solve them, in order to ensure that the welding quality meets the requirements.

Prevention of wave soldering welding needs to be comprehensive from the welding process, technician training, equipment testing, welding parameter control, welding speed and other aspects of the start, to take a series of effective measures in order to effectively avoid the occurrence of welding defects, improve welding quality and productivity. I hope the above method will be helpful to you, I wish you good luck in your work!
