A typical question that we get when it comes to welding mild steel is whether or not it can actually be welded. The short answer to that question would have to be, yes. It can be welded.
There are 2 basic types of wire that one can use to weld mild steel. On the one hand, we have ER70S – 3, an AWS classification. This type of wire is mainly used for all-purpose welding. The thickness of the welding wire that you decide to use will really depend on the type of material that you’re welding. A good, kind of neutral material to use would likely be a .03-inch diameter wire – it would be great for welding metals of a wide range of thickness and purpose.

How do you know if you’re welding mild steel?
For all intents and purposes mild steel can simply be regarded as steel with a very low amount of carbon in it’s makeup. It’s a very simple material to form and is also very common when it comes to MIG welding.
How do you choose a brand for welding wire?
The first thing to make sure of when you first start even considering purchasing welding wire is the quality that you want. If you want a high quality welding wire then you will likely require wire that meets the AWS standard for welding wire.
The AWS standard requires that wires meet a certain level of thickness and have a certain degree of tensile strength.
Where do you store welding wire?
Again, if you think it’s a good idea to buy welding wire then you likely understand that you will need a place to store it.
The most important thing to keep in mind when you’re looking for a place to store your welding wire is that it’s protected from the harmful material in the atmosphere. Keep your wire out of damp environments as this will cause it to oxidize and likely be rendered unusable over time.
The reason that you want to make sure your wire is protected is because it will likely not be possible for it to work correctly if it’s faulty and installed back into your welder. Faulty or rusted wire will likely lead to welding failure in the future.
How do you choose the right size for your welding wire?
There are really only 3 things that you want to make sure you pay attention to when sizing your wire.
- You want to pay attention to is the size welding wire that your machine can take.
- You want to make sure the wire is the right wire for your machine. Don’t buy flux core wire if you’re using a MIG welder.
- Make sure that the wire you use has a thickness that is proportionate to the material that you’ll be welding. If you’re welding a thinner metal, then you likely want to make sure that you use a thinner wire. Vis Versa for thicker metals.
