Mild Steel and TIG Welding
There is a lot of confusion about what type of welding is right for you. The truth is, there is no one right answer regarding welding. In this article, we will go over some types of welding and their pros and cons.
Mild steel and TIG welding are popular types used to weld thin metal plates together. Mild steel Welding is less heat resistant than other types of welding, so it’s not always the best choice if you need to weld thick pieces of metal together. On the other hand, TIG Welding is much more heat resistant and can be used to weld thicker pieces of metal together.
The advantage of using mild steel and TIG welding is that they can use to weld various metals. Mild steel is easy to weld and weld most types of metal, while TIG welding is more powerful and can be used to weld heavier metals.
Both mild steel and TIG welding have advantages and disadvantages, but they offer a great range of welding options. For a versatile welding technique that can be used on various metals, mild steel and TIG welding are two great options.
Once you have some experience with mild steel and TIG welding, you can branch out into more complex projects. For example, you can use mild steel welds to create complex shapes or assemblies.
Additionally, TIG welding is a great option for repairing or replacing parts on vehicles and other equipment. So whether you’re starting from scratch or just looking for an alternate way to weld, mild steel, and TIG welding are sure to fit your needs.
How TIG Welding Works on Mild Steel
TIG welding is a type of welding that uses a special torch called a Tig welder. The Tig welder uses a high-frequency current to weld together pieces of metal. This method is popular because it is fast and produces a good weld joint.
Things You Will Need:
When welding mild steel, you will need to use a filler rod. Mild steel doesn’t hold an electrode like other types of steel, so you will need to use more filler rods to strengthen the weld joint. It would help if you were careful not to overheat the joint or the metal while welding.
Process of How TIG Welding Works on Mild Steel
The inert tungsten gas (TIG) welding process uses a small amount of an inert gas like argon to weld metal. TIG welding is one of the most popular welding processes because it has a few key advantages over other welding processes.
Welding with TIG is the most efficient method for welding thin-walled metals, such as stainless steel and aluminum. The process also produces less heat than other welding processes, making it ideal for delicate and complex parts.
- To begin, you will need to prepare your workspace. You will need a torch with a TIG tip and a filler stick.
- Next, adjust the torch, so the tip touches the metal you want to weld.
- Turn on the gas at full power and wait until the metal begins to glow orange.
- Once the metal starts glowing orange, turn down the flame and hold the filler stick against the tip of the torch while you slowly move it around the area you want to weld.
- Use short, rhythmic pulses to weld the metal together.
- Be sure not to overheat or scorch the metal!

Mild Steel TIG Welding Voltage and Welding Polarities
When welding mild steel, be sure to use the correct welding voltage. This will depend on the type of weld and the polarities of the electrode and metal being welded. The following is a list of welding voltages for mild steel and their corresponding polarities:
Welding Voltage Polarity
220V AC ±10%
230V AC ±10%
240V AC ±10%
Welding with a tungsten/rod electrode is usually done using a welding voltage of around 270-300 volts, while using a tungsten/wire electrode requires a higher voltage, such as 330-350 volts.
How DC TIG Welding Polarity Works for Mild Steel
DC TIG welding is an extremely versatile welding process that can be used on various materials. One of the benefits of DC TIG welding is that it uses polarity to help create a weld.
While, Polarity works with DC TIG welding by using an alternator to create a positive and negative voltage across the tungsten wire. This causes the tungsten to heat up evenly, which in turn creates a strong weld.
Types of TIG Torches for Mild Steel
TIG torches are a popular choice for welding and cutting mild steel. Here are four types of TIG torch that are best for welding and cutting mild steel.
This type of torch has a rotating arm to create a flame. It is good for welding and cutting mild steel because it has a wide range of heat settings.
Direct-Drive TIG Torch type of torch has a motor that drives the arm. It is good for welding and cutting mild steel because it has a precise, controlled flame.
This type of torch uses gas to create the flame. It is good for welding and cutting mild steel because it produces less heat than other types of torches.
Portable torch is small and portable. It is good for welding and cutting mild steel because it has a short arc time, which means it can weld quickly.
TIG Welding Machine Set-Up for Mild Steel
When you’re looking to weld mild steel, there are a few things you need to take into account. This includes the type of welding machine you’ll be using, set-up tips, and material considerations. Here are some key points to keep in mind when tig welding mild steel:
1. TIG welding is a great choice for mild steel because it produces a very strong joint. The heat from the arc can also be easily controlled, making it a safe option for beginners.
2. Make sure your welding machine is properly set up before starting your project. Make sure the voltage and amperage are correct, and make sure the heating element is on correctly.
3. When welding Mild Steel, always use a flux-cored wire. This will help ensure a strong weld and protect the surface from corrosion.
4. Always take care when handling your welding rods and wire; they can be very hot! Use protective gear whenever possible to prevent burns or injuries.
What to Consider while TIG Welding Mild Steel?
There are a few things to consider when TIG welding Mild Steel. The most important thing to remember is to use the correct filler metal. A few other things to keep in mind include:
- Keep the welds clean and tidy – This is especially important when welding Mild Steel, as it can be easily affected by rust. Make sure to use a good cleaner and brush after each weld to remove any dirt or oxides.
- Use the right shielding gas – When welding Mild Steel, you’ll need to use a higher concentration of shielding gas than you would with other types of metal. This is because the alloy content of Mild Steel is higher than other metals, which can cause spatter and slag.
- Make sure the arc is maintained – One of the main problems with Welding Mild Steel is that it’s easy to overheat the metal. Make sure to watch your welds closely and maintain an even arc throughout the entire weld.
What polarity is used for TIG welding mild steel?
It is the same polarity used for stainless steel TIG welding, which is argon. Note that mild steel does not contain enough carbon to also be called stainless.
What should I set my TIG welding regulator to?
The TIG-welding regulator I use is a 7500 regulator. It goes up to 7500 psi and is a mix between the regulator I used in my welding shop (a Porter Cable) and the one that welders were using back in the 70s. It has a positive stop on the flow.
This means that when you start welding, it starts out flowing at 50 psi, and there is no adjustment screw to change this. Once you reach your desired pressure, it stops flowing and stays there regardless of what pressure you set.
What is tungsten for mild steel?
Tungsten for mild steel is a standard, widely accepted trade name for a non-oxide tungsten electrode. It consists of tungsten powder which is mixed with black flux (a binding agent) and some binders to form a porous mass that is then pressed into the required shape.
What should argon be set at for TIG welding?
Argon should be set at 30 cubic feet per hour (cfh) to 40 cfh, depending on your gas burner.
Why is my tungsten melting?
Temperature can be a factor in how fast the tungsten is lost. If you’re using a north-facing window as your light source and have been running it for four hours, it’s likely that the temperature difference will have caused the tungsten to start losing its heat.
Setting up a tig welder for mild steel can be a daunting task, but with the right tips and equipment, it can be a relatively simple process. Before getting started, make sure to have all of the necessary parts and tools available, including an arc welder, gas supply hose, shielding gas bottle, and spark plug.
Next, unpack your tig welder and read the instructions carefully to get acquainted with all the features. Once you are familiar with how everything works, it’s time to get welding!
