Tungsten Inert Gas (TIG) welding is a process that can be used to weld various types of metals. However, to make sure that everything goes well, it is vital to follow some rules.

In this article, we&#;ve listed 7 best practices you must take to perform an efficient and successful TIG welding procedure!

1. Ensure the cleaning of the material and place to be welded

Before starting any welding procedure, make sure that everything is free of impurities. Contamination damages the final result. Therefore, make sure that the tops to be welded have no oils or fats. Also check that the protective gloves and the material to be used are also clean.

2. Use the appropriate tungsten electrode

Each material and procedure has its characteristics. Therefore, you should always analyze the type and diameter of the most suitable tungsten electrode. When making this selection, consider the current intensity and the constitution of the protection gas that will be used.

3. Correct the electrode

Always prepare the tip of the electrode before starting work. Correct it in the direction of the shaft, leaving it pointed, if it is to be used direct current, or more rounded, if you apply alternating current.

To sharpen the electrode, use the stone in the opposite direction of the tip. In this way, it reduces the hypothesis of breaking the end.

4. Check the sensitivity of materials to the gas

If welding sensitive materials, use appropriate protective gases. By doing so, you will be preventing their embrittlement by oxidation.

5. Use the appropriate amount of shielding gas

The shielding gas used in the welding process should have its flow adjusted to the torch size. It is this gas that prevents oxidation. Therefore, even after the completion of the welding, it should continue to flow for some time to protect the fusion bath and the electrode.

6. Position the rod correctly

For a perfect result, use the rods correctly. Avoid oxidation by ensuring that the tip of the rod stays under the protective gas jet throughout the procedure. It must always be at an angle to the material to be welded.

7. Ensure procedural safety

For all welding processes, there are safety standards that must be followed. Check the rules of the materials and machines you will use and follow the instructions exactly. If you find any defects in the equipment, do not proceed.

Never forget to wear protective equipment as your safety is also essential for perfect welding!

The 5 Golden Rules of Welding

If you can&#;t see you can&#;t weld.

Ensure your lenses are clean.

You cannot expect a good weld if you cannot see the weld preparation and where you want the weld to go.

If you are not comfortable you will not get a neat weld.

Make sure you have good control over the arc. Try writing without leaning on the desk, your writing will be messy. Same with welding. Support your arm to reduce movement.

You cannot get a good weld if your equipment is not running properly.

A formula 1 driver will not be able to perform at their best with poorly maintained equipment. Same with welding. You will constantly be stopping and get an inferior weld if your machine isn&#;t running properly.

Weld from the bottom up.

Like building a house, you cannot start the bricks at the top. Weld metal is a liquid. When it goes in it needs support, that is why we need to always start at the bottom.

Weld metal is always a liquid and wants to find its own level. Weaves need to always be level, or the weld metal will sag.

If the foundation on a house is not level and straight, the bricks will end up the same. Get the foundation (first run) straight and level, so you can have something to follow.

If your weld run is wobbly, straighten it up with a grinder before laying your next weld, otherwise, you will only end up following the wobbly shape.

Technoweld can provide all the welding training that you require. We have extensive experience in adult education and understand the elements that make up a successful welding training program.

From basic gas metal arc welding, advanced welding, or welding programs in the use of exotic materials, we deliver the training that meets your needs.

We also offer on-site training for staff groups. Our training team can work with you to facilitate a training that has been modified to your specific job, abilities or welding project.
