How to avoid intermediate frequency inverter spot welder spatter? [DCS13]
Dec 28,2023
In order to avoid the spatter of intermediate frequency inverter spot welder, we should know the reason of the spatter of intermediate frequency inverter spot welder, and then solve it pertinently.
In a word, the spatter from intermediate frequency inverter spot welder is mainly because the temperature field of metal during plastic deformation and liquefaction can not reach the required pressure due to electrical mobility.

In order to avoid the spatter, on the one hand, we need to implement welding cautions, on the other hand, we can also take some targeted solutions.
The main points are as follows.
1, Routine cleaning for the spot welder must be done before and after daily welding operation. The parallelism and dimensional tolerance of the workpiece surface should be strictly controlled every time before welding, and the dirt on the workpiece surface should be removed to make the surface meet the welding requirements.
The dirt on the moving part of the arm should also be cleaned to ensure its sensitive movement. In addition, clean the worktable and weldments after welding operation.
2. Find out the pressure range of pre-pressure, welding pressure and post-welding forging according to the estimation and experiment.
On the basis of pressure settings, the welding pressure section which does not produce the critical pressure of welding spatter is defined, which is convenient to ensure the quality and reliability of the welding joint and its production efficiency.
3. The pressure distribution on the interface between the welder and the welding object is not uniform, which leads to the local high density and the early melting spatter of the welding object.
4. The rational use of self-inductance, Zeebek effect, potential difference and proper welding pressure can improve the efficiency of heat energy utilization, reduce energy consumption and improve the quality of weldin. It is the beneficial way to accelerate welding speed and also an important link to avoid spatter.
5. Flowing water should be used for cooling before welding. The temperature of the water from the welder outlet shall not exceed 40 °C. The temperature rise of the arm shall not exceed 70 °C. Not only to avoid electrical components out of control, but also to ensure the flexibility of the arm movement, and good mobility of the welder.
