Which Is the Best Anti-Spatter?

When it comes to anti-spatter, there are a wide range of choices – aerosol cans, nozzle dip, buckets, spray bottles, 55-gallon drums, etc. and deciding on the best one can be quite a challenge. Typically, you can reduce the amount of spatter while welding by setting good weld parameters and maintaining the right torch angle. However, despite this, after you complete welding a piece, you may require to use anti-spatter to clear any spatter that may have formed during the welding process.

So, which is the best anti-spatter to use? When you are choosing an anti-spatter, the most important aspect to consider is how the product will be finished finally. If the piece will be covered by another piece, is it is going to be painted and does it require grinding? All these aspects will help you decide whether you require to use an anti-spatter or not.

Factors to Consider before Buying Anti-Spatter

Painting

If the material will be painted, then it is best to use water-based anti-spatter and you must make sure that it does not contain silicones and is water soluble. The silicones prevent the paint from sticking to the metal. Water-based anti-spatter usually atomizes when the arc transfer occurs or it can be wiped off with a cloth easily. If you make use of oil-based anti-spatter on the parts that will be painted, you will need to clean the parts using a solvent, which takes a lot of time and this is also not environmentally-friendly.

Component Parts

If you are fabricating a part, which is a component of some other part and does not require painting, then you could use an oil-based anti-spatter. The drawback of using oil-based anti-spatter is that is messy and difficult to clean up. The best way to use it to lightly mist the workpiece with the oil-based anti-spatter and if you use it sparingly, you can wipe it off with a cloth.

Grinded Parts

If there is some part which requires grinding, there is no need to use anti-spatter. However, if the grinder cannot reach certain joints, it requires the use of anti-spatter, which can be wiped off later when finished.

Dips

You can use a nozzle dip to prevent spatter from building up on the torch consumables. All you have to do is dip the end of MIG torch in nozzle dip when the torch is warm. Just a quick dip of the torch can help to prevent the spatter from sticking to the equipment. Another way by which you can keep the spatter away from the consumables is by using chrome- or nickel-plated nozzles.

Aerosol Spray Cans

Anti-spatter compounds are also available in the form of aerosols. These aerosols produce a fine mist; however, the delivery agent may be flammable and so these are not very popular. Today, more OEMs and automotive tier suppliers are environmental and safety conscious and make use of non-aerosol and water-based anti-spatter sprays.

Colour and Size of the Anti-Spatter

The colour of the anti-spatter does not affect the effectiveness of the anti-spatter agent in any way. Usually, a specific colour is added to the anti-spatter to differentiate the product of one manufacturer from another.

If you make use of a lot of anti-spatter agents, then it may be more cost-effective to buy a 55-gallon drum and transfer it to smaller bottles for welders to use. However, if storing a 55-gallon drum is a problem, then you can buy the anti-spatter in smaller quantities.

An anti-spatter agent very important, especially in welding and fabrication units. It helps to prevent the welding spatter from adhering to the metal surface permanently and helps to reduce the time spent on post-welding processes like grinding and finishing, thereby increasing productivity.
