Anti Spatter Spray
How Effective an Anti Spatter Spray Can Be
Weld spatter is always a problem among welders that’s why the anti spatter spray products are also becoming popular because of the convenience it offers in preventing spatter. Spatter are small molten metal particles that splash around your welding work while welding. Because certain things can create irregularities either on the plasma or with the wire or weld pool, the effect is like dropping a ping-pong ball on a small puddle of water and the momentum creates an impact that forces some of the water to splash out.
Weld spatter are generally produced by MIG welding and can be caused by many factors. It could be due to low amperage or voltage setting, thermal or magnetic arc blow, wrong wire size, the wrong mixture of gas, lengthy wire, dirty metal surface, or due to draft that contaminates the weld pool. But in any way, spatter would always need to be cleaned up which could be bothersome for any welder. Removing a large amount of spatter manually can take a lot of time and the result would always appear to be a messed up cleaning job.
If you ever have problems cleaning up spatters every after work using tools, then you better consider taking on a preventive measure which our best suggestion is using welding anti spatter spray products. If you have questions about how these products work, what chemicals are they made of, how do you use them, and how or which products to choose, then better read on because you will never weld without one near you after reading this.
What is a Welding Anti
An anti spatter spray can act as a barrier against sparks and spatter not only during welding but also during cutting and grinding of metals. This barrier serves as a protective layer against molten metals by keeping it from adhering and damaging the metal it lands on. Some of these products can contain silicone and comes in water or petroleum-based including some solvents. Take note that any anti spatter product should be applied before the welding process and when the metal is cold. They also come in the form of gel or dip and you only need to dip the torch nozzle before welding to avoid spatter from sticking in.
Application is easy using the spray. Shake the can thoroughly and spray a light coat on the work area to where the spatter you think might reach. You can also spray your welding project a little to prevent weld splatter from sticking to the hardened weld. Splatter are those that look like carbon deposits on top of the weld which look like scars and should be removed.
After spraying the area, you can lay down your work and start to weld. When you’re done, let the metal cool off and wipe off the liquid that contains the slags and spatter deposits with a clean rag and you’re good to go for another spray and welding job. Remember not to spray your welding project too much with the chemicals because experts said the chemical components of the anti spatter spray for mig welding can also cause porosity on your weld. You must also spray the nozzle of your torch but avoid wetting it too much to prevent it from dripping liquid into your weld pool. After welding, wipe off the tip of the nozzle and spray again before use.
Components of Anti Spatter Spray
The latest form of anti spatter spray for mig welding is available in liquid and spray form. These products contain soy lecithin and n-propyl bromide (NPB). The soy component prevents the adhesion of the spatter while the NPB serves as the organic solvent in dissolving and emulsifying the soy component. The liquid form can be applied by brushing, sponging, swabbing and the spray is for spraying around the welding spot and also on the nozzle of the torch. This mixture is rendered safe, non-toxic and doesn’t contribute to the depletion of the earth’s ozone layer.
Lecithin comes from the fats of animals and plants’ tissues including egg yolk that contains a lot of natural fatty acids. But to derive lecithin easily, it is the soybeans that is now the main source for lecithin oil and is utilized in the formulation of protective products including products against weld spatter. Unfortunately, lecithin based anti spatter products are not very much available in today’s market.
On the other hand, what we can find today are those that are water-based and contain methylene chloride. Yet, according to studies, methylene chloride can be toxic to humans while it can also contribute to the depletion of the ozone layer. Nevertheless, we should advise you to wear protective masks when using anti spatter spray with methylene chloride and as much as possible use these on cold metals to avoid the formation of bead-like droplets that could render the liquid ineffective.
When it comes to products that are made to improve your work, you may find that there are also some bits of disadvantages in using it. This includes the products for anti spatter spray for mig welding. So here are things you should know to avoid overusing them.
Most of these products can be harmful to your health and to the environment especially those that contain methylene chloride. So always wear a respirator to avoid inhaling the fumes. Also, avoid those that contain silicone because these might contaminate your work.
Some of them can leave greasy residues that may need another use of chemicals to completely clean the grease out from the surface of the welding table. If applied on metal that needs to be painted later on the grease can pose a problem.
Some types can stain or darken metals like those with harsh chemical contents.
Can cause porosity on the weld if applied too much especially on joints where the liquid can get trapped. So don’t ever try spraying joints with any of these products.
Water-based anti spatter spray products when used in humid environments can induce rusting of metals.
To help you find the right anti spatter spray products and avoid getting those that could bring some negative results on your work, we have reviewed a number of them and we’ve found two welding anti spatter spray items that are worth keeping in your garage together with your MIG.
