This method gives very good control, resulting in extremely precise and clean welds, especially on the thin materials like aluminum and stainless steel. TIG welding is very versatile but still often needs more skill and time than other processes, hence, it is the favorite for detailed or visually critical projects.
TIG Weldingとは?
📌 TIG Welding Definition
TIG welding, also known as Tungsten Inert Gas welding, is a very accurate welding method that uses an inert gas, either argon or helium, and a tungsten electrode for metal joining. The process gives high-quality, clean welds, which is why it has become the preferred choice for very thin sheets and delicate workpieces.
Process and Technique of TIG Welding
TIG welding is one of the welding processes, where an electric arc is generated between a non-consumable tungsten electrode and the metal part to be welded. The heat produced by the arc is very high, which melts the surface of the metals and a weld is created. A shielding gas, usually argon, is used to prevent the weld area from being contaminated by the atmosphere. In most cases, a filler rod is needed to supply material for the weld; however, direct welding is also possible. The welder has to precisely control the temperature, gas flow, and electrode position to create high-quality and accurate welds, which makes it a process requiring expertise and great care.
🔑 Key Process Elements:
- Electric Arc: Generated between tungsten electrode and workpiece
- Shielding Gas: Typically argon, prevents contamination
- Filler Rod: Optional, supplies additional material
- Precise Control: Temperature, gas flow, and positioning crucial
Equipment Used in TIG Welding
TIG welding process uses a specific set of tools and equipment for accurate and high-quality results. The main pieces of equipment are a TIG welding machine (power source), a tungsten electrode that does not get consumed, a supply of shielding gas (usually argon or a mix of argon and helium), and a torch for holding the electrode. The application of filler metal in the form of a rod may be done in case of welding thicker metals that need more metal than what is already there. Moreover, dominantly heat input is ruled through the use of accessories like foot pedals or hand controls, while welding helmets and gloves are the protective gear used to guarantee safety during the process.

What is Arc Welding?
📌 Arc Welding Definition
Arc welding is a process of electric welding where an arc is created and metals are melted and joined together. The arc produces very high temperature that melts the metal at the joint, thus it fuses and forms a strong bond when cooled. This technique is very adaptable and can be used for different kinds of metals, applications, and it is mostly employed in construction, manufacturing, and repair works.
Process and Technique of Arc Welding
Arc welding reality is to make an electric circuit through the welding machine, the electrode, and the workpiece. The start of the arc then gets passionately between the electrode and the metal surface, thereby producing the super-high heat which is enough to melt both the parts, and the material thus liquefied becomes a part of the weld pool, and when it cools down, it gets into a very strong unbreakable bond. This method of welding requires very skilled hand movements for keeping the arc length constant and as well controlling heat thus avoiding defects. Depending on the application, one can use different kinds of electrodes and also the shielding gases of his choice to improve the weld quality.
