Tungsten inert gas welding, or TIG welding, is additionally referred to as GTAW, or simply gas tungsten arc welding. Whilst much like gas welding. This utilizes a tungsten electrode to produce the actual arc as well as heat for your weld.
The advantages to utilizing TIG welding will be it can easily be employed to weld much more types of metals as well as alloys. You will get thoroughly clean welds. You won’t get spatter or messy welds that require cleanup by grinding. Tig welding produces an excellent robust, clean, plus neat and tidy weld.
Before starting welding you need to make sure that you take all the proper safety precautions. You need to have a good quality welding mask preferably for tig welding. The light given off by arc welding is enough to burn your eyes, and it can burn your skin, like a sunburn. Make sure that you are wearing leather gloves and a leather welding jacket to protect your arms and neck. Make sure that your jacket fastens all the way up to your neck. You want to wear heavy cotton shirts and trousers. You also need to wear heavy closed shoes. You should have a welding screen and warning sign so others can avoid the area, and you need to make sure it’s well ventilated.
Once you have set up all the safety precautions, it’s time for you to get down to welding. Before you can do any welding you need to make sure that you have the right electrode. Different metals need different tungsten electrodes. Grind the electrode down so that it has a nice point. When you are welding that point will get worn down to a rounded tip. A pointed electrode tip gives you a better weld. It will be smaller and more directed.
Make sure to grind away from you so you don’t contaminate the electrode. After you grind the tip, you need to put the electrode in the right holder. Then you choose the right settings on the welding machine. Different metals need different settings. Check your manual for the right settings.
Clean your metal and your table. That will give you the best welds. Clamp your metals down to your table so they don’t move when you are welding.
To start a weld keep the tip about an inch from your metal. You don’t want the tungsten tip to actually touch the metal. You want to heat your metal quickly so you can start the weld pool from the arc created. Use the electrode to create a weld pool then add filler material as required.
The way you weld depends on what metal you are welding. After you finish your weld you might want to grind it down, depending on if it is going to be seen or not. That will also give you the chance to check your weld to make sure that there are no holes or gaps.
It may take some practice to get good welds, but don’t be discouraged. Once you have it, you can weld just about anything.
