Want to know the tips for accurate, smooth and perfect stainless steel tig welding? Stainless steel welding always requires specific tips and techniques to weld it without any colour change and bubble formation.
Both beginners and professionals must need to follow the tips for excellent welding work.
Improvements to Your Stainless Steel TIG Welding
In this article, here we bring the 6 best tips for safe and accurate stainless steel tig welding. By following all these techniques, you will get an unexpected brilliant result of welding.
There is no shortcut to these tips for stainless steel welding.
In every welding work, the cleanliness of metal is the welder’s priority to make an accurate and perfect thing. But in tig welding, it is one of the most crucial things to clean all the metal surfaces and joints properly before starting welding. You can not follow any shortcut here if you want perfect results.
If you do not clean the metal surface, bubbles will form during welding. These bubbles not only decrease your work quality but also weaken your surface. You can clean your metal surface as much as you can want.
To clean the stainless steel surface, a clean rag is very helpful. But you have to spend more time and effort using the rag.
The other best way to clean the surface is through the use of acetone and other thinkers. These thinners will clean the stainless steel surface in just seconds without extra effort while also evaporating very fast.
2. Tungsten rod
In the market, there are different types of tungsten rods available. Some are pure tungsten, while others may contain some additives with them. Both types of rods do not make much difference in your welding work and quality.
The main difference between them is that some have excellent long-lasting ability in arcing while some have quick and low arcing ability.
All these things matter, but the main thing to consider during accurate welding is tungsten rod diameter.
If you use a large diameter tungsten rod to weld a light metal sheet with low amps, your weld will not be accurate, flat, and consistent.
The key to precise welding is to select the rod diameter with your sheet weight. If you weld a heavy stainless steel sheet with a large diameter rod, you will definitely get your expected result in the end.
3. Gas coverage
The colour of stainless steel can be changed during welding if you use a bad technique.
If the air gets involved in welding, this thing will change your stainless steel colours during its welding. Not only the colour is changed, but the surface also becomes rough and includes bubbles in it.
This is the only solution that will increase your gas coverage under your economical budget to prevent this problem.
The more you will use the gas to weld steel, the more you will get a perfect result without colour change.
4. The clean, sharp tip
Dirt is one of the biggest reasons that destroy all the welding processes. If your tungsten tip is dirty, you will never get the perfect result. Most of the time, welders clean the tips, which helps them a lot in welding.
But if you do not clean the tip and start welding, then you will get a dirty tip weld at the end. When the filler rod joins the hot tungsten tips, they melt and create a blob on the tip.
With a dirty tip, you will never make a perfect arc design. All of your efforts will be ruined in the end.
A ground tip can only make a perfect arc shape with excellent precision. To make a superior quality clean arc, only one thing is needed; one is a fine point, and the second one is a smooth finish.
5. Speed of welding
The stainless steel surface is not as sturdy as other heavy metals. There is not too much heat needed for its welding. If you use an extra amount of heat to weld it, you will not get the desired result in the end.
On the other side, it is also not suitable to slow down the heat level. This thing will slow down your work and will consume more heat to finish the project.
The only key to welding perfectly is to use enough amperage to give you good results without affecting the accuracy.
The usage of amperage also varies from person to person due to their capability and welding style. The best practice is running the welder with medium heat and doing the welding fast to comply with the heat.
6. Project cooling
Stainless steel is sensitive to heat, and it can quickly wrap into any shape by an excess of heat. During its welding, you will also see different colours like red, blue, and black.
All of these colours are the result of excessive heat. Welding is not possible without heat, and you can not melt any metal without heat. But the welding of stainless steel needs more specific heat to melt it and weld it for different things.
One of the best things we like to tell you is that you can make an eye-catching weld joint without any colour changing effect.
This thing is only possible with good penetration. The only thing to remove the blue, red, and worse black colour from your welding is only done by using the right amount of heat.
The control of heat is very important to get colour free welds. During continuous welding, the amount of heat increases continuously, and ultimately it affects the colours of welds. To avoid this problem:
- Take breaks during welding.
- When you start the project, keep an eye on its colours.
- When you notice the colour of the welds is changing, stop welding, and let the section cool down. This process will keep your welding colour free and prevent the irregularity of shapes due to overheating.

Rolling up the article, we hope that these improvements tips will make your tig welding more accurate and fast. The stainless steel tig welding is interesting and nice only if you follow the right steps.
The major reason for most welder failure in stainless steel welding is that they try to do their work by shortcuts. You can follow a shortcut in another metal welding, but in stainless steel welding, there is no shortcut to follow.
