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!
