TIG Welding Brass

Yesterday, we talked about TIG Welding when it comes to Aluminum, so today we move on to TIG Welding Brass. What is brass? Brass is a type of metal alloy that has been made from the combination of copper and zinc. The portions of the two mentioned will depend and can be varied to be able to create a wide range of brasses that have varying properties. In a way, we can say that brass is some sort of substitutional alloy. The atoms of these two may replace each other as long as they are withing the same crystal structure.

 

Yesterday we also learn a little bit about TIG Welding. TIG is the most complicated welding process to learn but the results you will yield in the end will prove to be worth it. In TIG, you will be need three main ingredients to perfect your weld and these are heat, shielding, and filler metal. If you can look back on our article yesterday, you will remember that TIG will require both of your hands when working, and this is what makes it complicated.  The heat will be passing through the tungsten electrode thus creating an arc to the metal. Electricity will supply the heat. The shielding gas will come from a compressed bottle of gas in order to protect the metal being welded from air. And lastly, the filler metal is just a simple wire that will be dipped by hand into the arc to be melted.

 

How Stay Focus On Welding

 

Before you weld, please make sure that your PPE is complete because TIG is a bit radioactive so protect yourself properly. Check you materials if everything is working as it should be. Check also the wires for short circuits and the tubes for any leakages. Make sure that everything that you need is withing arms reach.

 

Now, a great thing about TIG is that it is able to weld just about any metal and this includes brass. This is made possible because the main gasses that are used are noble inert gasses. A thing to remember about these types of gasses is that their properties in no way alters the weld properties. TIG is simply pure heat and compatibility of the filler wire. Since brass is a copper alloy, you will have to use pure Argon but sometimes, other welders also use a combination of Argon and Helium (75/25).  I am not sure if this happens to everyone but usually, the weld will have a muddy feel to it but I believe that this can be reduce by lowering the heat. Look closely at the metal, if it’s too dark, you are using too much heat. An expert welder said that a technique for copper alloys would be to keyhole the root open on the joint. This means that you will strike your arc and then, create a keyhole that is to be followed by dipping the filler wire into it. Keep repeating until you are done.
