Today we are going to learn about how you will be able to get rid of MIG weld spatter when you finished a weld. But of course, it is important to remember that prevention is better than cure. To be honest, once the weld spatter has dried and stuck to the weld metal, it will be a bit harder to remove it. In the end, prevention is better than cure. You should always be mindful of the amount of spatter in the weld metal, since the spatter could ruin the finish of the metal. It won’t look good.
Spatter is made up of little bits of metal that are sent flying away from your welding area caused by your welding arc. As I said above, too much spatter is not good for your product since it usually signifies that it is made of low quality. I’m sure you don’t want your costumers to think that too. It also makes you welding area messy to look at and can cause visibility problems. It’s hard to completely avoid the appearance of spatters, but there are ways that you can reduce it. To know how to avoid it, of course, you must first be aware of what causes it. There are several factors that can cause spatters, but the main reason is that there has been some kind of a disturbance in the molten weld pool that happens during the transfer of the wire into the weld. Most people would understand that this is caused by the relationship between the amperage and the voltage.
But that’s not all of course, excessive spatter could also mean that your arc length is too long. You could try and shortening your arc length and see what happens, but do keep in mind that the general rule for arc length is to not let your arc get much longer than the diameter of your electrode’s metal core. So for example, your electrode has a 1/8 inch diameter core, you should keep your arc length near or at 1.8 inch as well. Hopefully, that will be able to help decrease the appearance of spatter.
Another cause could be that because you use too much wire. Too much of something is bad and so is too little of something. You must find that perfect balance. If you are getting spatter everywhere, you can try and slow down your wire feed speed for a little bit and observe what happens. Did the spatter lessen? Can you control it better now? If after your observation and adjustment, it still doesn’t work, then you may want to consider that the spatters could be a result of the arc blow, which occurs when magnetism in your base metal affects the quality of your arc. In order to counter the effects of the arc blow, you may want to try welding toward you ground clamp. The ground clamp is a metal strip that is used for making electrical connection with the ground. If that doesn’t really do anything, you may want to switch your welding machine to alternating current.
It would be better if you can just test it first on a scrap piece of metal so you don’t waste good metal to be welded. You want to be sure before you use it on the actual product that you want to be welded. If you are satisfied with the reduced amount of spatter and you are still able to produce a solid weld, you can now proceed to the real thing.
