Weld spatter is a common problem when welding. It can be very frustrating when trying to clean the welds, and the spatter sticks to everything! In this blog post, we will discuss 10 tips for how to keep weld spatter from sticking in order to make your job easier.
What Causes Weld Spatter?
Weld spatter is a waste material that occurs as metal melts and drips from the electrode during welding. It often appears as small balls of molten slag or drops, particularly when arc welding on stainless steel or aluminum with AC current.
The reason why weld spatter forms has to do with resistance, it happens because atoms want to move around within the metal until they find an easier path through which to travel.
This causes them to leave behind smaller pieces in their wake (which become weld spatter). In most cases, this phenomenon is unavoidable but there are some ways you can reduce its appearance.
How to Keep Weld Spatter from Sticking: 10 Best Tips
Tip 1: Practice Good Welding Technique
Practice good welding techniques, and you’ll be less likely to leave excess weld spatter on your metal. Keep in mind that you’re going to do everything possible to avoid welding defects.
Tip 2: Polish the Metal Before Welding It
Polishing your metal before welding it will help ensure a smooth finish when you start working with MIG or TIG welders, and odds are good that there won’t be any excess spatter left on the surface of the material afterward. In addition, polished metal is much easier to clean up after you’ve completed your welds.
Tip 3: Clean Off Excess Spatter After You Finish Welding
Some people have success grinding off extra bits of filler wire from their workpieces if they notice too much spatter has built up during a project. Others prefer using steel wool for this purpose because it doesn’t damage the metal.
Tip 4: Use a Wire Brush After Welding
Using a wire brush immediately after welding can remove excess spatter from your workpiece, but you should understand that this might cause some surface damage to take place as well. In addition, it’s going to be difficult for you to avoid scratching or marring the surface of your metal if you’re brushing over it with a stiff-bristled tool like this one.
Tip 5: Preheat Your Metal Before Welding It
Preheating is another option for removing weld spatter in most cases because it prevents oxidation and helps ensure an excellent bond when you use MIG or TIG welders on steel projects. The downside here is that preheating adds to the complexity of your project, so you might not want to use this technique on something that’s especially time-sensitive.
Tip 6: Use a Heat Gun After Welding
Using a heat gun after welding can help remove excess spatter from metal projects in some cases. However, it should be noted that using an open flame device like this one poses certain risks and could result in fire damage if used improperly.
Tip 7: Try Using Water Instead of Other Remedies
Water is often effective at removing weld spatter without causing any serious damage or creating safety concerns for people who are working with MIG or TIG welders on steel projects. This tip works well when working above ground level but isn’t as effective when working at ground level because the water is likely to run off of your workpiece.
Tip 8: Make Sure You Clean Off Excess Spatter
It’s essential that you clean excess spatter from your metal before it starts to rust or corrode if you want to avoid problems with discoloration, oxidation, and other issues related to poor surface preparation. It should be noted that some people prefer using a wire brush for this purpose but understand that doing so might damage the appearance of their material in certain cases.
Tip 9: Use Welding Gloves Rather Than Wire Brushes
While most welders agree one way or another about whether they enjoy using welding gloves versus stiff-bristled tools like wire brushes for cleaning up after finishing a project, it’s generally easier to use gloves as long as you take the time to remove any excess spatter that might be caught in them.
Tip 10: Avoid Welding With Too Much Current
If you’re having trouble keeping weld spatter under control while working with MIG or TIG welders on steel projects, one potential solution is to reduce the current running through your welding machine by adjusting its controls. Doing so will help ensure there isn’t too much heat being generated at once and that no oxidation takes place during the process of melting filler material into various pieces of metal.
