Although TIG welding can be carried out without gas, the process is risky and should not be performed on projects that require a lot of strength and toughness. But, this does not mean you can not weld without gas. Argon is included in the TIG welding process to shield the metal against damage and prevent the electrode from burning.
If none of these are of any concern to you, then you are good to weld without gas. This is especially useful in the case of beginners that are practicing their skills and are not working on large projects that require additional safety and protection. This article provides insights into what TIG welding without gas actually is and how you can perform it. So, keep reading the article below for more information in this regard.
TIG Welding Without Gas
What is TIG Welding?
TIG welding is a welding process in which a tungsten electrode is used to create a weld pool. These electrodes are non-consumable in nature and thus, provide high-quality output. Most elders prefer TIG welding because of its less consumable and highly efficient nature. Another benefit of the process is the high precision and accuracy, which makes it stand out among the rest of its counterparts. We have compiled the advantages and disadvantages of TIG welding, you can have a look.
TIG Welding Without Gas
TIG welding is a process that requires actual gas such as Argon for shielding the metal. Thus, it plays a very important part in producing high-quality welds that are tough and sturdy in nature. Without Argon, the resulting product might be brittle and prone to damage. However, as mentioned earlier, this does not mean you can not weld without gas. Indeed you can, but you must be extremely careful while handling the metal.
In addition to this, you must maintain a clean workspace and ensure that there are no flammable materials present nearby that can potentially lead to damage. One thing that you should keep in mind is that tungsten electrodes are prone to burning in the absence of Argon gas and, thus, must be carefully handled to avoid unwanted accidents. In some cases, Helium is also used as a replacement for Argon to prevent the contamination of the welding site. The process varies among various welders and thus, must be carefully considered for the best results.
TIG Welding Without Gas: Step by Step Guide
We recommend choosing contemporary materials and apparatus over traditional ones when planning on welding in the absence of gas. This will minimize the damage to a great extent and will also provide ease of use, thereby leading to time efficiency. One thing we want to highlight here is that the process requires increased precision and must be performed by either skilled individuals or under the guidance of an expert in the case of a beginner to avoid unwanted mishaps. Below included is the detailed step-by-step guide on how to TIG weld without using the gas.
Step 1: Taking Required Precautions
The first step involves taking all the precautionary measures before moving ahead with the task. This step is recommended for all welders despite their skill level and must be performed to prevent damage to health and product while working. We also advise keeping the workplace clean and free from flammable materials as the electrode is prone to burning in the absence of Argon.
Apart from this, temperature shall also be monitored carefully after regular intervals to prevent the overheating of the welding machine. Wearing helmets and other safety gear is also highly recommended for personal safety and protection.
Step 2: Keeping the Clean Metal and Workspace
As mentioned earlier, it is important to keep your workplace clean. Along with the workplace, you should also keep the metal free from any dirt or dust to generate dirt-free, high-quality output. This is not necessary when using the gas for welding purposes as gas can eliminate all the impurities present on the metal. But, if you are not using gas, those impurities will remain there unless you clean them by yourself. So, we suggest properly cleaning the whole area and all the materials before welding for the best results.
Step 3: Choosing the Welding Equipment
After you have made sure that everything around you is clean and free from impurities, it is time to pick up your tools. Yes, choosing the appropriate welding equipment is as important as any other step. Choosing the wrong apparatus can significantly impact your performance and might also lead to negative consequences. There is a wide variety of such products available in the market that are versatile in nature and can be used for a diverse range of applications.
However, when it comes to TIG welding, we recommend going for contemporary tools as opposed to traditional ones. This is especially useful for TIG welding without gas. You can opt for welding machines that possess 115-volts welding units. The reason for this is their ability to penetrate into thick metal layers without any inconvenience or additional effort. Welding units with 115-volts power work really well with 8-inches deep metal layers and enable you to weld with extreme precision and accuracy.
Step 4: Organizing the Metal Pieces
After the above-mentioned steps have been performed, the next step focuses on organizing all the metal pieces together. This is especially useful to prevent the loss of an important piece in a messy workplace. Furthermore, keeping the metals at the required position will improve your working efficiency and will enable you to weld with utmost precision and accuracy.
This is followed by choosing the appropriate electrode for welding. I have previously mentioned the role of electrodes in the TIG welding process and its significance. Here I would again emphasize the fact that since gas is not being used in the process, you would need a flux core to proceed with the process. Similarly, you can also adjust the general as well as advanced attributes of the welding system to achieve the most out of it.
Step 5: Let’s Begin
As all the prerequisites for the welding machine and process have been sorted, now it is time to start the welding process. It is a widely known fact that you must keep the temperature into consideration and it should be consistent during TIG welding. However, you have no chance to show negligence inconsistency when doing it without gas as it might lead to unimaginable consequences.
In the absence of gas, the welding process might produce a lot of smoke and odor due to the loss of electrodes and increasing temperature. This often hinders the visibility of most welders and might contribute to less accuracy and precision. Being consistent in such situations can lead to better accuracy and will lead to a better outcome. For beginners, we highly advise practicing their hand movement and control over the welding machine before attempting welding without gas.
Step 6: Removing the Contaminants
Last but not least, it is time to remove all the contaminants from the welded product once the task is complete. Welding can create a lot of smoke and ashes in the workplace. Additionally, it can also leave various temporary marks on the surface of the metal, which might look untidy. Thus, as a final touch, we recommend brushing off all the excess dirt and contaminants from the newly welded surface for a clean and tidy outlook. Similarly, you can also grind the area lightly to achieve a well-putted and tidy outcome.
Alternatives to TIG Welding Without Gas
There are various alternatives that can be adopted to avoid performing TIG welding without gas. The most prominent among which include modern and versatile tools to perform the tasks. Our ultimate recommendation in this regard is the use of a 2-in-1 TIG/Stick Welder that allows you to weld with utmost efficiency and precision. In addition to this, these items are budget-oriented and thus, can be afforded by a variety of consumers.
However, make sure to use small-size electrodes with these devices to prevent the formation of a large welding pool, especially if you are going for TIG welding. Smaller pools are better for TIG welding as opposed to large pools that are suitable for Stick welding activities. Furthermore, you can also opt for Helium instead of Argon as the gas if you do not want to weld using Argon. The reason for this is the budget-friendly and performance-oriented nature of the Helium, which makes it an ideal option for a wide variety of welders.
