Common Factors Causing Welding SpatterHowever, it is quite common. After all, I temperatures are being generated to create the welds, causing metal to melt. As it melts, this metal can spatter, ruining an absolutely beautiful joint created by the welder. So what causes this, and what can be done to reduce it from occurring? These are questions we look to answer in this article.
Welding MetalsFirst of all, it is important to understand that certain metals or materials are perfect for welding. Steel is one such example. Many products, including cars and buildings are put together using a welding process. Here are some common causes of spatter.
Metal CompositionIt is also important to understand that these materials play a significant role in how much spatter is produced. Some metals are far more likely to spatter, which depends greatly on the metal composition. There are other metals that are not designed for welding at all. One of the properties of these metals is that they are not weldable. You are likely to find that there are going to be some circumstances where metals are sold as weldable when they are not. If the composition of the metal is the problem, then the solution is an easy one. Maybe you just need a new material. There are several different kinds of materials that can do the same job and greatly reduce the spatter. You may be working on a project where spatter does not matter much but, if it does, then consider using a different material to get the best look for your project.
Metal CoatingThere may be some instances where you are required to use a material that has a metal coating. This coating was required prior to the weld. This can include such things as galvanized coatings, chrome, paint, rubber, or metal plating. Anything that may cover the surface of the metal. Most welders recognize that the purer the material that is being used, the better the weld they are going to get. It will be much cleaner and far less likely to spatter. Unfortunately, there are many instances where a coating is used, creating a nightmare scenario.
Dirty MetalsOne of the most common causes of spatter is dirt or debris. This can be oil, dirt, dust, grease, even the markings from pens. If this is the case, a thorough cleaning is important before welding. This will help to remove the potential for spatter.
How to Reduce Welding Spatter?Reducing the welding spatter is quite hard but possible. You just need to be careful and take a few steps as shown below:
The Right Weldable FillerOne way that you can decrease the amount of spatter is through the use of a quality filler. However, if you use the right metals to make the weld but your filler, either wire or rod, is of poor quality, then you are going to have spatter issues. Here are some of the common filler issues that result in spatter.
Low-Grade FillerThis is probably the most common issue related to spatter. People try to save themselves a block and wind up having a major issue with spatter as a result. If you want good clean welds, then you need to make sure that you have a filler that is of good quality. This is one of those instances where you truly get what you pay for.
Contaminated FillerLike with contaminated material that is being welded, contaminated filler can also be an issue. Oil, dust, dirt, or other debris get in the filler, it will lead to an excess amount of spatter being produced. One thing you need to do to prevent this is to make sure that you are properly storing your filler when not in use. This not only prevents it from getting rusty, but keeps dust and dirt from getting on the filler. To be stored in an airtight container and kept at a constant temperature to prevent degradation.
Welder SettingsThe welder settings is also extremely important. If you are wanting to prevent spatter, the wrong settings can factor in helping you to accomplish that.
MIG SettingsOne of the most common causes of spatter in MIG welding is excessive speed irregularity in the continuous wire feed. In this type of weld, spatter occurs as the filler wire is added to the weld pool. The wire melts because of the extreme heat that is generated. This causes the filler to turn into a liquid, which creates a pool.
SMAW SettingsThis principle is exactly the same when performing an SMAW weld. The heat needs to be just the right temperature and the rod fed at the right rate to ensure that you get the perfect well. If the weld is too cold you were going to find a significant amount of excessive spatter is produced. This creates a very ugly appearance. If it is far too hot, that it will create a lot of spray, leading to spatter across the material. One of the things you can do to help prevent this type of issue is to spend some time practicing this welding technique. The better you get at this, the less likely you are to have spatter occur. This is an additional step to take beyond ensuring that the feed rate and temperature are correct.
Welding GasTwo gases play a significant role in the amount of spatter that is produced. These are Argon CO2. These two gases are used to create a shield that protects from atmospheric conditions affecting the integrity of the weld. They are most often used in MIG welds. CO2 is a commonly used gas because it is far cheaper than argon. However, it also is more likely to produce spatter than argon is. A common solution to this problem is that many welders use a mixture of argon and CO2. In the right amount of each, the welder can save some money and still get a quality shield to protect against spatter.
