How Beginners and Skeptics Can Learn TIC Welding?
The TIG welding is more sophisticated than most of the welding procedures out there. It requires a high level of practice, time and groundwork compared to the others. Even though, it is always fruitful to learn TIG welding even if you are currently working on stick welding or MIG welding. There are quite a few reasons, which may push you to learn TIG welding. For example, the TIG welding delivers the most precise and easy to control the welds. The TIG welding can be monitored via machine or foot pedals. You can start working on various types of metals by choosing any of the six electrodes.
How To Learn TIG-Welding?
Even if you have no idea regarding the precise controlling capability or other features of TIG welding, the following walkthrough on TIG welding may help you to start learning as soon as possible.
How To Prepare for TIG Welding?
You need to make sure that the surface of the metal you are working on is clean and ready to go. You can do so by grinding the surface or brushing it off to remove any pollutants from it. You should keep a separate set of brush or grind wheel when it comes to cleaning your material for TIG welding. You can use a clean piece of cloth with acetone to remove other metal shavings or machine oils.
The TIG welding process depends heavily on the preparation process. You can get away with minor setbacks on the stick welding process, but TIG welding is not as forgiving, especially on the training process.
Choosing Your TIG Welding Electrode
Next step is to choose the perfect welding electrode for the job. The use of electrode is an important part of the welding process. That is because it transfers the welding arc to the workpiece. The six types of electrode are 2% thoriated, 1.5% lanthanide, zirconiated, 2% created and rare earth pure tungsten. Electrodes can be balled, truncated, pointed depending on the power level used in TIG welding. We shall now look at choosing the perfect electrode.
The pure tungsten electrodes are renowned for their price point. They provide a stable arc on both aluminum and magnesium workpiece. They also get along well with the AC welding jobs. The thoriated and created electrodes are better matched with DC welding jobs. Use of sharp point is very common in the 2% thoriated, 2% created, 1.5% lanthanide, and rare earth electrodes. The sharp edges are formed due to the placement of the electrode right into the grinding wheel.
The Thoriated electrodes are the most popular among the six types of electrodes. These electrodes have tungsten into which thorium is mixed. They provide a big electrode tip, which is likely to stay sharp for a much longer period, especially compared to pure tungsten. Proper ventilation is a necessary have regarding thoriated electrodes as they are radioactive. These electrodes are very popular in DC welding projects such as stainless steel, titanium, nickel, and steel.
The created electrodes work best regarding DC welding projects along with low amperage ones. The low amperage projects often include small and delicate parts. Various kinds of metals are used in the weld such as stainless steel, carbon steel, titanium and nickel alloys. The Lanthanated electrode has some applications in both Ac and DC welding jobs. They ensure stable arcs while being very useful on low currents. They are widely used by welders in square wave power source projects.
The zirconiated electrode is excellent when it comes to welding on AC welding projects. They are durable and capable of providing resistance to contamination. Be advised not to use them on DC welding jobs as those jobs need a higher current capacity. The zirconiated electrode also contains ball tips.
The rare earth electrode is available in various categories depending on different manufacturers. They provide a stable arc for both AC and DC welding jobs. They are durable and comes in some diameter in size. You can pick the right one for you depending on the job.
TIG Welding: The Modifications
There are thinner TIG welding gloves available to provide extra grip and dexterity. They help a lot when feeding the filler materials at the same time of applying heat. According to experienced welders, you can still get a hot finger if it is closest to the arc. It is called the “TIG Finger.” Extra padding is often suggested on the welding gloves when it comes to the TIG finger.
The stubby gas lens kit is also a very usefully accessory in TIG welding. They are very helpful when welding into tight spaces. Depending on the project, the usefulness of the stubby gas lens it may vary. The welding job gets much easier with a stubby lens kit if you are stuck in a very tight spot.
