Tips For Improving Your TIG Welding Efficiency

(Last Updated On: January 9, 2021)

TIG welding, by its very nature, is a relatively slow operation. But it is a very flexible one as well. We can potentially use it to weld more materials, even exotic and heavier alloyed metals, than any other welding method. It is also well suited for thin materials, as it produces a low heat input to avoid burning. No matter the application, TIG welding can provide extremely high-quality welding when done properly.

However, it is not always easy to produce such good results; it is a matter of preparation and practice as it is plain patience. Fortunately, arming yourself along the way with a few tips will considerably increase the operation’s quality.

Invert The Mechanism

One of the first steps you should take to enhance TIG welding performance is using an inverter power source. Up to 50,000 times/second, inverters work by converting high-voltage, low-amperage alternating current (AC) to direct current (DC) back and forth at a very high-speed rate. A smooth arc that offers consistent welding efficiency is the end outcome.

Inverters also have frequency controls that allows you to calculate the amount of time it takes for the device to complete one full current cycle (the combined time spent on positive and negative electrodes) and change the frequency from 20 Hz to 400 Hz. By narrowing the arc’s focus, the frequency function of the inverter helps boost the welding performance, which in turn produces a narrower weld bead and minimizes the heat-affected area. With this feature, to complete the weld, you will need less time and filler metal and obtain faster travel speeds. You will minimize the potential of burn-through and the need for rework by reducing the heat-affected region.

Inverters also have a balance control that allows you to change how long the current spends in each part of the AC cycle, particularly if aluminum is welded.

Keep Cool & Versatile

You can also help make the process more effective by choosing the correct TIG torch for your application. Find a torch with decent insulation first. For example, silicon rubber insulation protects against high-frequency leakage and/or cracking, resulting in premature torch failure and torch changeover downtime.

Also, decide whether you need a TIG torch that is air- or water-cooled. For low-amperage applications or those below 200 amps, It may use air-cooled versions. If you are welding fragile materials under 3/16 inches, they are the best choice, and/or you need to be able to switch quickly from one region to another, as they do not require an external cooler.

For applications over 200 amps, you can consider a water-cooled TIG torch. This form of torch helps avoid overheating and allows you to reach faster travel speeds, all of which allows the more welded metal to be placed down in less time.

Consider the angles you need to weld when choosing a TIG torch, as maneuvering around complicated joints can be time-consuming, not to mention awkward.

Less Can Be More

Preventing overwhelming will increase your TIG welding performance dramatically, and it can also save your money. Overwhelming occurs when more welded metal is inserted in a joint than is needed to achieve the required weld strength. It is often the consequence of bad joint-fit or planning, incorrect welding parameters, or plain overcompensation. Unfortunately, overwhelming wastes gas and filler metal shielding, and it increases welding time.

Remember, no operation for welding is flawless. It can even become more effective with some know-how and a bit of practice, even if you use a relatively slow method like TIG welding. The key is to make sound decisions about your choice of equipment and take note of the weld’s size that you are finishing. Ultimately, taking that little bit of time up front will save your time and cash in the long run.
