Spatter in welding is a common occurrence and that’s probably why you are here because you want to get rid of it. Spatter is especially common in GMAW or that’s Gas Metal Arc Welding. Spatter is the droplets of molten material that are generated from the or near the welding arc. Of course, spatter isn’t nice to look at. It’s considered as a nuisance or a defect. Take a look at the following images for spatter:
It doesn’t look nice, right? It looks messy and poorly made. Your costumers or boss will not be pleased when they see this in the final product. So what can you do to get rid of them? Don’t worry there are other ways to help you. But before we talk about getting rid of them, it would be best to know what causes them in the first place so we can try and avoid them. Plus, it will save us a lot of time when it comes to cleaning up.
Some causes of spatter in welding are:
(1) Incorrect Settings. You should always double check the settings like the amperage, voltage, and the electrical stick. To discuss this further, amperage is mostly dependent on the wire feed speed. An amperage that is too high will create a lot of spatter. A solution for this would be to decrease the wire feed speed or increase the voltage. When it comes to voltage, if it is too low, spatter will increase. Naturally, the solution for this would be to increase your voltage.
Next is the Electric Stick Out factor. This refers to the distance from your contact tip to the work piece. Stay with a distance of 3/4″. Too much stick out will cause a lot of spatter so double check before working!
(2) Dirty Surfaces. It may be hard to believe but dirty surfaces actually create more spatter. It would do you good to take time to clean the welding materials before starting. It could be rust, oil, paint, or other things.
(3) Shielding Gas. This is an uncommon cause but not impossible. If you have checked everything else, and can’t seem to find the cause of the spatters, then you should check this one. Remember that the higher the Argon content, the smoother the arc, but Argon is quite expensive so many welders opt to use carbon dioxide which is a cheap choice. However, keep in mind that it creates a lot of spatter.
If all else fails to rid of the spatter in welding, you can always purchase anti-spatter sprays at Amazon or at a local store near you. They do not eliminate the spatter but they make it easier for you to wipe off the spatter. If you have further questions, feel free to message us or leave a comment below! We’d love to hear from you!
