What is TIG Welding?
- Of the three common welding processes, TIG welding is the most complex and challenging to master. So what exactly is TIG welding? TIG welding refers to Tungsten Inert Gas welding .And as its name suggests, this method uses a tungsten electrode. (toolfaqs.com)
- Tungsten is a unique metal that requires a lot of heat to melt. In fact, it has the highest melting point among all metals in pure form. Therefore, the tungsten electrode used in TIG welding does not melt to provide filler material. (toolfaqs.com)
- Instead, a separate filler rod has to be used to provide filler material for the weld pool. Unlike in stick welding, the electrode only works in TIG is to pass an electric current. The wire does not have any flux coating. (toolfaqs.com)
- As such, a separate gas bottle is required to provide the shielding gas. In most cases, a mixture of helium and argon is used. (toolfaqs.com)
Benefits of TIG Welding:
- The cleanest process and it does not produce splatter or waste. (toolshaunt.com)
It produces aesthetically appealing and precise welds. (toolshaunt.com)
The foot pedal allows you to control heat input. (toolshaunt.com)
High degree of precision is possible with TIG. (toolshaunt.com)
TIG Welding Applications:
- When you think about stick vs. tig, the first that comes to mind is which process is used for what. TIG welding requires a clean surface. Thus before welding, you have to clean the metals. Also, it is best suited to welding thinner metals. (toolfaqs.com)
Therefore the main applications of TIG welding are the welding of metallic ornaments. Also, it is used in the fabrication of small intricate components. This can be in the automotive, shipbuilding, or even airplane industry. As a matter of fact, TIG welding was developed for the aircraft manufacturing industry. (toolfaqs.com)
Main Equipment Used in TIG Welding:
- By now, you probably have an idea of the equipment used in TIG welding. First, are the power source and the welding machine. In addition to these, you will need a gas tank as well as a filler rod. (toolfaqs.com)
The filler rod is separate from the electrode. The filler rod is usually made from the same material as the metals you are welding. On the other hand, the wire is made of tungsten. (toolfaqs.com)
How Does a TIG Welder Work?
- TIG, or tungsten inert gas, welding is also known as GTAW (Gas Tungsten Arc Welding). TIG welder parts include a non-consumable tungsten electrode that runs a current through the metals being joined, a computerized controller for timing welding operations, and a robotic arm assembly for moving the welding tip into place. Unlike MIG welding, the TIG welding procedure may or may not use a filler metal for the welding supply. (marlinwire.com)
- Like the MIG welding robots, TIG welder machines are programmed to perform the weld. During the TIG welding procedure, dangerous sparks or filler could burn employees. Rather than risk harm and to provide better consistency, robots are programmed to perform the welding while the human welder supervises. (marlinwire.com)
- An inert gas is used during the process to protect the welding area from being contaminated. Common inert gasses used in the TIG welding procedure include argon and helium. Unlike the MIG process, a filler is not always needed in TIG welding but is used when welding together metals with high melting points to prevent cracking. (marlinwire.com)
- Since filler materials can produce weld spatter on the workpiece surface, using TIG welding for direct metal-to-metal welding produces a neater and more attractive finish without needing extra steps such as electropolishing. (marlinwire.com)
