Generally, TIG welding provides more flexibility and versatility when compared with other types of available welding processes. Though, it is also a tough job to handle TIG welding while doing projects. Hence, with some extra effort and good practice one can be more proficient in using TIG welder and can smoothly perform TIG welding tasks.
Typically, Tungsten Inert Welding or we can say, TIG welding or Gas Tungsten Arc Welding (GTAW) is a type of arc welding that is used to produce the high-quality pure weld. Due to this reason, this TIG welding has commonly be used in extremely sensitive projects where there is no compromise on quality. For instance in nuclear aviation, pharmaceutical industries, and food and beverages. Here in MIG welding has been used to perform jobs by using a metal coil which is fed continuously with the gun, On the other hand, the TIG welding can cause the base metal to be meltdown when the filler metal is hand-fed within the molten pool. Thus, this type of welding can be done on different base metals such as stainless steel, aluminum, carbon steel, and other non-ferrous metals.
So one cannot give much better advice than this, as if you are serious about becoming a great TIG welder then you should develop the highest level of patience along with great practice sessions. For us, this advice work as a wonder, thus we make this our motto and always suggest new TIG welders follow this during their baby footsteps. Though, if holding a welding torch in your hands before initiating the project doesn’t excite you then we recommend switching your welding type with this as it will not be a good option for you as a career.
We don’t mean to dishearten you, but we still want people who are serious about TIG welding they should continue their passion as their career. To give our new welders more ease we are here to give people some amazing tips and tricks. We are sure that these tips can help you in learning, improving your skills, and keeps you in the right direction. Pectizing these tricks in your daily routine will give you confidence, makes you draw a consistent arc, more control over the weld puddle, and help you in producing great welding results every time.
Top 15 TIG Welding Tips for Beginners
These are the simple yet effective techniques that can help you in completing your welding job in time while making your life even easier.
1. Weld by using the minimum power source
When one begins practicing their TIG welding then he/she must always make sure to mark the minimum power settings into the puddle. At the start, you should give your weld puddle enough energy to sustain. It is essential to remember that TIG welding is based upon penetration. So giving too much power means you are going to burn down the base metal right away. Hence, your power level is always an important part of your welding technique.
2. Keep your metals clean
Remember, TIG welding always needs a clean metal to perform an effective job. Without clean metal, you cannot create a solid weld or sturdy arc. You must have a dedicated brush Top useful TIG welding tips and tricks. Even before beginning the new project put some extra minutes on cleaning can always bring amazing outcomes.
3. Using the correct tungsten
When working on a different surface while using a TIG welder, you will notice that you need different tungsten for this task, for instance, the welder who is working with aluminum, there is a large chance where you can use green tungsten. Also, red tungsten is linked with steel. So there is no need to be afraid and memorizing all. With practice, you will learn more about equipment.
4. Thickness of Tungsten must be considered
Every pro-TIG welder will always say that the thickness of the tungsten is always a matter. So if you got something too large that you will need more heat to begin your process especially when striking the arc. Whereas when you are dealing with too small tungsten then you might encounter a chance to risking your base metal to get overheated and damage the welds.
5. Identify the time to regrind your tip
Knowing the tip of your tungsten is important to make sure the tip is touching the weld puddle. You might get forced to regrind the tip. Over time the tungsten develops a ball. And you will find the low-quality tungsten arc. Since quality is the key part of TIG welding which can never be compromised. So if you find tip causing negative aspects on the quality then for the welder, take it seriously as a warning alarm to smooth the tip by regrinding it. Also, there is a chance of an encounter with an accident while balling with the project, hence make sure you save your time by keeping ready several tungstens.
6. Keep consistent during the welding process
During TIG welding the welder is required to maintain its focus from beginning to end. Make sure you have already eliminated the distractions from the welding environment that may cause disturbance and interruption during your welding process. As it is always a good choice to stock up some additional fillers rods quite closely with you, so you can easily grab them without adding breaks into your workflow.
7. Equip with the proper safety equipment while grinding
For some beginners that don’t realize the amount of safety, they should follow with TIG welding. Though, TIG welding spatters and sparks free that don’t even produce any fume or smoke. But they should know that tungsten electrodes are slightly radioactive. Especially when you are grinding the TIG welder to create a fine tip. Wearing a welding respirator that is designed to protect the airway passage should become imperative. Afterward, it is important to pick a place where there is minimalistic dust and dirt and place your welder to keep the tip safe. Also, add decent ventilation within your workspace for your regular welding.
8. For your electrode grinding stay consistent
Consistent is the key especially for beginners so when you grind the tungsten then going lengthwise is always a smart choice. Hence, this way you are onto creating an even result whenever you do welding. Mostly, the TIG welders can use a tungsten sharpener though, for the beginners who just initiate the journey, it is suggested to go with a bench grinder. Hence, it will do a marvelous job. Depends upon your choices and the vast options available, we still want you to do grinding jobs without contaminating your electrodes.
9. Get to know about your shielding gases
Commonly, 100% argon is used as a shielding gas for doing TIG welding. Furthermore, the ratio of argon and helium 75:25 respectively is also a popular option among welders. The more you increase the helium in your shielding gas, the more temperature will begin to fall which in other words can cause problems in striking the arc finely. So if you add 100% helium as a part of your shielding gas then you will find it much difficult in initiating the welding process. So set your shielding gas at 15-20 cubic feet/hour during your learning on how to weld through TIG. A higher setting can eventually blow out your weld.
10. Whenever possible use bigger rods
The logic behind using the bigger rod is quite simple and straightforward. So if you are having a larger rod then you will find ease in the feeding process. The standard rod with TIG welding equipped usually holds a diameter of 3/32 or below. Hence, going with a 1/8 inch diameter rod will facilitate you more in learning the process.
11. Angle of your rod and torch shouldn’t be the same
If you are putting rod and torch at the same angle while you are working with your TIG welding equipment then you will make the heat have a “bounce” during your work. Since at this process you are enabling the rod to properly meltdown before you want that melting to happen. Hence, it will create an inferior bead. So to save you from such a mess you should feed the rod into the welding pool.
12. Instead of an abrupt end, slowly reduce your arc
When the welder is welding by using TIG weld at a defined temperature then he must keep the foot pedal or with any type of temperature control mechanism around 3/4th of the way down. Doing this will give you the ability to let the arc trail off when you reach the ending points of the weld. Shutting down the welder machine suddenly will eventually cause a high rate of cracking the base metal.
13. MIG and TIG are often interchangeable
There is a chance (very often) when the welder uses a wire from MIG welding to create a TIG weld. Although it’s not a regular thing often there is some chance of your welding equipment getting interchanged. Most likely multi-process welding machines also offer 3 or 5 in one welder.
14. Protect yourself from shocking
The most easiest and common way to decrease the shocking hazard threats for your welding is to create a non-conductive environment by placing something on it. The use of welding gloves is common that can prevent you from shocking your arms. Consider wood products as you’re another good option. Remember your sweat can conduct more electricity that needs great care to tackle. So keep resting your arms that hold the torch.
15. Thin gloves sometimes work great with TIG welding
If you are on wearing thin gloves on your hands that are used to feed the rod then you will have a more real and improved texture in the process. If your gloves are bulky, thick, and heavy then it will prevent you from having maximum control over the welding process. This way it will affect the overall quality of the results. Also, it will help you in learning how you can feed the rod by using fingers more realistically.
