Welding is a complex but rewarding skill that can be used to create metal structures and components. For Welding steel, tungsten inert gas (TIG) welding is an effective technique. It requires precision and patience, but when done correctly, the results are strong welds with clean lines. Let’s take a quick look at how to use Tig Welding for steel.
Equipment Needed for TIG Welding Steel
TIG welding involves using a non-consumable tungsten electrode that produces an arc, which in turn melts the filler rod and the metal being welded together. To get started with Steel Tig Welding, you will need the following items:
An AC/ DC power supply
This is what powers your welder and creates the arc.
A foot pedal
The foot pedal connects to the power supply and is used to control the current output of your welder.
Shielding Gas
Argon or helium are usually used in steel TIG welding applications because they protect the weld from atmospheric contamination while also offering greater penetration into thicker metals.
Filler Rod
Filler rods come in different sizes based on their thickness and tensile strength. Select one that matches your project requirements.
Welding Process
When you have all of the necessary equipment ready, you can begin the actual welding process. First, secure your workpiece, so it doesn’t move around while you’re working on it. Then, set up your shielding gas according to the manufacturer’s instructions—generally, this would involve attaching a regulator to a tank of argon or helium gas before connecting it to your torch via a hose or pipe fitting. Next, adjust your power settings by selecting an amperage range that is appropriate for the type of metal being welded (thicker metals will require higher amperages). Finally, make sure that your workpiece is at room temperature before beginning to weld so there won’t be any warping due to heat stress during the process. Once all these steps have been completed, you can begin welding!
Conclusion:
Welding steel with TIG offers many advantages over other methods, such as MIG or stick welding, because it delivers precise and consistent results with little need for repairs afterwards. Its ability to penetrate thicker materials also provides additional benefits over other methods. When performed correctly by someone who has taken proper safety precautions and has all of the necessary equipment available, TIG welding steel can result in strong welds with clean lines every time!
