Spatter in welding is fairly common so don’t think that you are the only welder out there who is trying to get rid or at least minimize it. Spatter is especially common for people who do MIG Welding and Gas Metal Arc Welding. When we say spatter, we are referring to the droplets of molten material, which is usually metal, that is generated from the or near the welding arc. Spatter isn’t nice to look at. It is considered as a nuisance or a welding defect, which is why you should know how to minimize it or get rid of it completely. Here are some pictures of welding spatters.
What do you think about it? Doesn’t it look messy and unprofessional? I’m sure your customers wouldn’t want to see these in the finished product that they will be paying for.
The question now is: how will you be able to get rid of them? Don’t worry, there are ways that you can and we are here to help you. But first, let us talk about what causes them so we can try to avoid it. After all, in the end prevention is still better than cure.
Here are some causes of welding spatter that you should be aware of:
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 you paid attention to the three causes and made sure that you aren’t doing anything incorrectly but there are still welding spatters, you can always turn to anti-spatter sprays that you can easily buy at Amazon or any online shop so you won’t have to go all the way downtown. They don’t eliminate spatter but they make it easier for you to wipe the spatter away. Here is an example:
This is CANTESCO’s AS-16-A Red Heavy Duty Solvent Based Anti-Spatter Soray.
You can purchase this item for only 6.41 US Dollars. Amazon will be able to give you free shipping if your total purchase is equal to or is greater than 49 US DOLLARS. Time to bulk buy!
This product will help prevent spatter build-up in your welding applications or processes. It is also non-flammable so it won’t easily catch fire. It is printable and contains no fluorocarbons. I must mention that it is also Silicone free.
