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.
Name the welding processes covered in this chapter which may use a shielding gas to shield the weld area?
Gas Tungsten Arc Welding Gas Metal Arc Welding Flux Cored Arc Welding
Whether HAZ is higher in gas welding or arc welding?
Larger in Gas Welding. In all arc processes the HAZ is concentrated in a couple inches around your bead. In gas welding it can be double or triple that size.
How is magnesium welded with out it being ignited?
Some methods are used: - electron beam welding - laser beam welding - gas wolfram arc welding - gas metal arc welding - resistence welding - brazing
What is the difference between gas welding goggles and arc welding goggles?
If by gas welding you mean-oxyacetylene welding. The difference is just that arc welding requires a darker shade of lens. When oxyfuel gas welding (OFW) usually a shade 5 lens is recommended. When arc welding, a minimum of shade 10 lens should be used (actually shade should be determined by amount of current used).
What is Difference between arc welding and gas welding?
There's some information on welding at http://www.WeldingFun.com .. should have the answer your looking for. Sorry for being to lazy to look it up

Difference between TIG MIG?
tungsten inert gas metal inert gas now refered to as gmaw gas metal arc welding.
What is the difference between the plasma and gas states of matter?
A gas is composed of atoms (noble gases) and molecules, such as oxygen gas. Plasma is composed of positively charged ions and unbound electrons.
What is a plasma arc?
A very high temperature form of welding and cutting metals, using a jet of plasma.Arc plasma is the temporary state of a gas. The gas gets ionized after passage of electric current through it and it becomes a conductor of electricity. In ionized state atoms break into electrons (−) and cations (+) and the system contains a mixture of ions, electrons and highly excited atoms.A typical value of temperature obtained in a plasma jet torch may be of the order of 28000 °C(50000 °F ) against about 5500 °C (10000 °F) in ordinary electric welding arc.
What is difference between gas and plasma?
The difference between gas and plasma is the physical structure. The gas turns into a plasma when the gas becomes ionized and loses its positively charged particles. They are similar because they both have no definite shape, but plasma responds strongly to magnetic fields and also emits 5x the electricity it puts in.
Which gas dissolves into plasma?
Hydrogen, helium, and argon are commonly used gases that can be transformed into a plasma state when energy is applied. This process is often used in applications such as plasma cutting and welding.
Difference between plasma to the other state of matter?
Plasma is a state of matter where atoms are ionized and have freely moving electrons. It is distinct from solids, liquids, and gases because the particles are not bound together. Plasma is electrically conductive and responds to electromagnetic forces, whereas the other states of matter do not.
What is the difference of plasma to solid liquid and gas?
Plasma only occurs at very high temperatures.
What is the difference between shielded and unshielded welding?
Shielded welding uses a shielding gas to protect the weld pool from contamination and oxidation, while unshielded welding does not use such gas and is typically done in a protected atmosphere like underwater or in a vacuum. Shielded welding produces cleaner and stronger welds due to the protection from atmospheric elements.
What is the main difference between FCAW and GMAW?
The main difference between Flux-Cored Arc Welding (FCAW) and Gas Metal Arc Welding (GMAW) is the type of consumable electrode used. FCAW uses a tubular electrode filled with flux to protect the weld pool, while GMAW uses a solid wire electrode with an external shielding gas. FCAW is often preferred for outdoor welding due to its self-shielding capabilities, while GMAW generally produces cleaner welds.
