Inverter spot welding, also known as medium frequency spot welding, is widely used in manufacturing industries for its high efficiency and high precision. However, spatter is a common problem that occurs during the welding process. Spatter refers to the scattering of small molten metal particles during the welding process. These particles can cause damage to the surrounding area and affect the quality of the weld. In this article, we will discuss the reasons for spatter during inverter spot welding and how to reduce it.
There are several reasons for spatter during inverter spot welding:
1.Welding current is too high: If the welding current is set too high, it can cause the metal to vaporize and produce a large amount of spatter.
2.Electrode angle: The angle between the electrode and the workpiece can also affect spatter. If the angle is too large, it can cause excessive heat to be concentrated in a small area, leading to spatter.
3.Surface contamination: If the surface of the workpiece is contaminated with oil, rust, or other impurities, it can cause spatter during welding.
4.Welding speed: If the welding speed is too fast, it can cause insufficient melting of the metal and lead to spatter.
5.Electrode wear: Over time, the electrode will become worn and not able to properly transfer current to the workpiece, causing spatter.
To reduce spatter during inverter spot welding, several measures can be taken:
1.Adjust the welding current: Ensure that the welding current is set to an appropriate level to prevent excessive vaporization of the metal.
2.Check electrode angle: Check and adjust the angle between the electrode and workpiece to prevent excessive heat concentration.
3. Clean the workpiece surface: Ensure that the surface of the workpiece is clean and free from oil, rust, or other impurities.
4.Adjust the welding speed: Adjust the welding speed to an appropriate level to ensure sufficient melting of the metal.
5.Replace the electrode: Replace the electrode when it becomes worn to ensure proper current transfer and reduce spatter.
By taking these measures, it is possible to reduce spatter during inverter spot welding and ensure a high-quality weld.
