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.

Who did the welding for the world war 2 machines?
Men and women did the welding. In the U.S. women were trained to use the TIG (heliarc) process as they were thought to have a steadier hand. In ship building there were more women welding then men as a big percentage of men were in the service.
Whyargon welding is prefer instead of electric welding?
To my knowledge there is no process called Argon Welding. Argon is an inert gas used to protect the weld puddle when using the GTAW (TIG/Heliarc) and GMAW (MIG) process. Almost all welding processes utilize electricity. OAW (Oxy-Acetylene now called Oxy-Fuel) being the exception.
What is used as a welding gas?
The gas is going to depend on what style of welding you are doing. For TIG (tungsten inert gas) it is 100% argon. For heliarc, which is a form of TIG, it is 100% helium. For MIG (metal inert gas) it is 75% argon/ 25% carbon dioxide. Finally, for gas welding, it acetylene and oxygen--separate tanks. (my son helped on this one)
Is Tungston Inert Gas with an aluminum rod considered welding or heliacing?
Heliarc was the name used when TIG welding was first developed during WWII. A tungsten electrode carrying the current to create an arc and utilizing helium as a protective gas. The process has evolved to utilize many different types of gasses. The name was changed to reflect this. The correct nomenclature is GTAW. Gas Tungsten Arc Welding.
Why is argon used as a shielding gas in welding?
Argon is used as a shielding gas in welding because it is inert, meaning it does not react with the molten metal during the welding process. This helps to protect the weld pool from contamination by oxygen and nitrogen in the air, which can lead to defects in the weld. Argon also provides good arc stability and coverage, resulting in a clean and strong weld.
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.
What is Welding process?
There is no BEST process for all conditions/situations/materials/applications. Easiest to use would probably be GMAW (MIG welding). Most useful for all applications and metals including cutting OAW (Oxy-Acetylene welding) usually referred a to as Oxy-Fuel. Most widely used process is probably SMAW (stick welding) which would also be most portable and cheapest to purchase. GTAW (TIG/Heliarc) is used mostly indoors on thinner and or non ferrous metals ( Aluminum, Stainless Steel, and most alloys. If I were to set up a shop at home I would consider a DC stick welding machine (preferably a rectifier type) and an Oxy-Acetylene setup.

Which electrode is used to weld stainless steel to carbon steel?
It depends on the type of stainless steel. Stainless steels come in various compositions and are identified by numbers and letters. Electrodes should be chosen that match these. For example when welding 316 stainless use type 316 electrodes. In a lot of situations you can safely use the next higher number. 304 stainless can be welded with 308 electrodes, 308 stainless with 310 electrodes. 309 electrodes are generally used to weld stainless to carbon steel.
What is the welding cert roster code for welding?

Name of the type of welding?
One type of welding is tube welding. Another type if mig welding.
Difference between ERW and SAW welding?
SAW welding is a type of arc welding while ERW welding is spot or seam welding. SAW stand for submerged arc welding while ERW stands for electric resistance welding.
