 Spatter in Welding: What is It & How to Prevent It

When you're welding, the last thing you want is for your project to be covered in welding spatter. But what is welding spatter, exactly? In short, it's the small molten droplets of metal that are expelled from the arc during welding. While it might not seem like a big deal, welding spatter can actually cause a lot of problems. Not only is it unsightly but it can also cause your welds to be weaker and more likely to break. 



In this blog post, we'll take a closer look at spatter in welding and how you can prevent it. 


What Is Welding Spatter? 

Welding spatter is tiny balls or droplets of molten metal that are expelled from the welding arc. These bits of metal can range in size from 0.5mm to 5mm. When they land on your workpiece, they stick to the surface and harden, making it difficult to achieve a smooth, even weld.

In addition to being unsightly, welding spatter can also cause problems with the functionality of your finished product. 


What Causes Welding Spatter? 

There are a few different factors that can contribute to welding spatter. One of the most common is using an incorrect welding technique. If you're not using the right voltage or amperage settings, you're more likely to produce welding spatter. 

Another common cause of welding spatter is contaminants on the surface of your material. If there's oil, paint, rust, or scale on your metal, it can cause problems with your weld and lead to an increase in welding spatter. 


How to Prevent Welding Spatter 

Now that we know what causes welding spatter, let's take a look at how we can prevent it. First and foremost, make sure you're using the right settings for your particular project. If you're unsure, ask an expert or consult your owner's manual. 

You should also clean your materials before you start welding. This will help ensure that there are no contaminants that could cause problems with your welds. Lastly, be sure to use the correct electrode for your project. The wrong electrode can also lead to increased welding spatter. 


Conclusion: 

Welding spatter might seem like a minor annoyance, but it can actually cause a lot of problems with your welds. In this blog post, we've taken a closer look at what causes welding spatter and how you can prevent it. By following these tips, you can help ensure that your next welding project is free of any unsightly spatter!

How Long Does a Tank of Argon Last For TIG Welding?

Image
Many people believe that the size of the tank is what determines how long it will last, however, that is not always true. It all depends on the welder's usage and needs. Below is more information on how long an argon tank usually lasts. By reading this article, you will learn: How long a tank of argon should last for TIG welding What size tanks are available for purchase How to get the most out of your argon tank Size Matters: When it comes to the size of Argon tanks, there are many different options to choose from. The most common sizes are 80, 125, and 160 cu/ft. The 80 cu/ft. tank is great for light welding and will last approximately 8-12 hours. 125 cu/ft. Gives you about 12-20 hours of welding time and is perfect for general maintenance projects.  Lastly, the 160 cu/ft. tank provides 20-30 hours of welding time and is usually used for production welding. Welding Time Depends on Current: The amount of time you can weld with your argon tank also depends on the welding current be...

Welding is a process of joining two pieces of metal together by using heat and pressure. In order to weld, you need to have a welder, which is a machine that produces the heat and pressure required for welding.  Welding Bed There are many different types of welders, but the most common type is the arc welder . The first step in welding is to set up your work area. You will need to have a welding table or some other type of work surface that is flat and level. You will also need to have a power source for your welder.  The most common type of power source is an electrical outlet but you can also use a generator or batteries. Once you have your work area set up, you will need to Choose the right type of metal for your project. The two most common types of metals used in welding are steel and aluminum. Each type of metal has its own unique properties that make it better suited for certain projects.  For example, steel is stronger than aluminum, but it is also more difficult ...
