The tungsteng electrode, because this one not is a filler metal in this process. The individual may be asking what metal can you not weld using the TIG process. In that case cast iron, zinc (including zinc coated metals), lead and any metal with a low melting temperature would be the answer.

What is the principle of tig welding?
Tungsten Inert Gas (orTIG) welding is also referred to as GTAW (Gas Tungsten Arc Welding) and by the term Heliarc® which was the Linde Company's trade name for the TIG process when it was originally introduced.The welding arc is started with a sharply pointed tungsten electrode shielded by inert gas. A separate filler rod is fed manually into the weld puddle in much the same way as is done when gas welding.The process is well suited for aluminum.
In which process is the electrode used in welding?
Manual Metal Arc Welding(MMAW) Also GTAW (TIG) and GMAW (MIG) The MIG wire carries electric current so it is considered the electrode. TIG the Tungsten is considered an electrode.
What are the kinds of welding?
There are a considerable number of welding processes that cover a vast range of metals and some nonmetals in most industries and applications. An excellent resource for welding information is The American Welding Society (AWS.org). A short list of the most common processes are: Oxygen Fuel Gas (OFG) which includes welding and cutting equipment where oxygen is mixed with a fuel gas such as acetylene, propane, etc. and a torch is used. Shielded Metal Arc (SMAW) sometimes called "Stick Rod" welding. This is a manual process that uses a flux covered wire electrode that melts during welding to form the filler metal. Gas Metal Arc Welding (GMAW) sometimes called "MIG" (for Metal Inert Gas) which is a semi automatic process that uses a bare or flux cored wire that is delivered by a spool drive during welding. Gas Tungsten Arc Welding (GTAW) sometimes called "TIG" (for Tungsten Inert Gas) or Heiliarc (trade name by the Lindy corp.) which uses a non consumable Tungsten electrode in an inert gas shielded gas torch. The Tungsten's produces the heat (via an electric current) and filler metal is added by "dipping" the tip of a bare wire to the weld puddle. The list goes on to include things like Electron Beam Welding , Plasma Arc Welding / Cutting, Friction Welding, Explosion Welding. Microwave Welding, Plastic Welding, etc.. Welding is used on everything from auto mufflers to space vehicles and medical instruments.
What type of welding process is used to join dissimilar metal?
friction welding can be used to join dissimilar metal. Also depending on the metals most arc welding processes and oxy-fuel can used. It's just a matter of using the correct filler material or electrode.
Gas tungsten arc welding?
why oxyacetylene filler rods cannot be used for gas tungusten ar welding
What is a tungsten in tig welding?
Tungsten is a metal used as the electrode in Tungsten Inert Gas (TIG) welding. It has a high melting point and is non-consumable, so it does not melt during the welding process. Tungsten helps create a stable arc and allows for precise control in TIG welding.
Definition of argon welding?
Argon welding, also known as gas tungsten arc welding (GTAW), is a welding process that uses a non-consumable tungsten electrode to create a welding arc. Argon gas is typically used as the shielding gas to protect the weld pool from atmospheric contamination. This process is commonly used for welding non-ferrous metals, stainless steel, and thin materials.

The most commonly used welding processes are?
There are a few commonly used welding process. The top used are shielded metal and arc welding.
What is the main difference between filler rods and electrodes?
Filler rods are used to add metal to a molten weld pool during the welding process and electrodes actually have electricity running through them to deposit metal into the weld with the exception of TIG welding where the tungsten electrode is used solely for heat.... Hope this was helpful
What services does TIG Welding offer?
TIG welding is a method of welding. A tungsten electrode heats up the metal that is to be welded while a gas, such as argon, protects the weld from being contaminated. This method allows for clean, accurate welds. It can also be used on more metals than any other welding process.

What is heliarc welding?
Now called TIG, or more correctly Gas Tungsten Arc Welding, this process was developed to weld Aluminum. Using an alternating electrical current ( A C ) through a Tungsten Electrode to establish an arc and melt the metal, Helium was introduced to protect the weld puddle from the surrounding atmosphere. Hence the name Heliarc. Tungsten is used as an electrode as it has a very high melting temperature.
What type of filler material is used for mild steel?
ER70S-6 is a very common filler metal when welding with Gas Metal Arc Welding or Gas Tungsten Arc Welding on a low carbon steel (mild steel). This can be purchased as a spool or in rod form.
What is a base metal in welding?
A base metal is also called the Parent metal. It is that metal in the welding practice that has been cut by the various forms of cutting, then prepared and is to be welded. Welding is performed to join one section of the base metal to another section of base metal by means of the various welding processes, e.g. SMAW(Shielded Metal Arc Welding) where welding welding rods are used, GTAW(Gas Tungsten Arc Welding) where Tig wire is used, FCAW(Flux Cored Arc Welding) etc. The welding rods, the TIG wires etc are called the filler metals, for they fill the weld gaps by depositing their molten-state weld metals.
What types of welding used for 8 mm thickness metals?
For welding 8 mm thickness metals, common methods include MIG (Metal Inert Gas) welding, TIG (Tungsten Inert Gas) welding, and stick welding (SMAW - Shielded Metal Arc Welding). The choice depends on the type of metal and specific requirements.
