wats the difference?

 

The diffrenence is in the way it is welded. TIG>MIG

GTAW Welding
Gas Tungsten Arc Welding (GTAW) is frequently referred to as TIG welding. TIG welding is a commonly used high quality welding process. TIG welding has become a popular choice of welding processes when high quality, precision welding is required.
In TIG welding an arc is formed between a nonconsumable tungsten electrode and the metal being welded. Gas is fed through the torch to shield the electrode and molten weld pool. If filler wire is used, it is added to the weld pool separately.


TIG Welding Benefits
Superior quality welds
Welds can be made with or without filler metal
Precise control of welding variables (heat)
Free of spatter
Low distortion
Shielding Gases
Argon
Argon + Hydrogen
Argon/Helium
Helium is generally added to increase heat input (increase welding speed or weld penetration). Hydrogen will result in cleaner looking welds and also increase heat input, however, Hydrogen may promote porosity or hydrogen cracking.

GTAW Welding Limitations
Requires greater welder dexterity than MIG or stick welding
Lower deposition rates
More costly for welding thick sections





Common GTAW Welding Concerns
We can help optimize your welding process variables. Evaluate your current welding parameters and techniques. Help eliminate common welding problems and discontinuities such as those listed below:

Weld Discontinuities
Undercutting
Tungsten inclusions
Porosity
Weld metal cracks
Heat affected zone cracks
TIG Welding Problems
Erratic arc
Excessive electrode consumption
Oxidized weld deposit
Arc wandering
Porosity
Difficult arc starting

MIG Welding
Gas Metal Arc Welding (GMAW) is frequently referred to as MIG welding. MIG welding is a commonly used high deposition rate welding process. Wire is continuously fed from a spool. MIG welding is therefore referred to as a semiautomatic welding process.


MIG Welding Benefits
All position capability
Higher deposition rates than SMAW
Less operator skill required
Long welds can be made without starts and stops
Minimal post weld cleaning is required
MIG Welding Shielding Gas
The shielding gas, forms the arc plasma, stabilizes the arc on the metal being welded, shields the arc and molten weld pool, and allows smooth transfer of metal from the weld wire to the molten weld pool. There are three primary metal transfer modes:

Spray transfer (MP3 Audio)
Globular transfer (MP3 Audio)
Short circuiting transfer (MP3 Audio)
The primary shielding gasses used are:

Argon
Argon - 1 to 5% Oxygen
Argon - 3 to 25% CO2
Argon/Helium
CO2 is also used in its pure form in some MIG welding processes. However, in some applications the presence of CO2 in the shielding gas may adversely affect the mechanical properties of the weld.





Common MIG Welding Concerns
We can help optimize your MIG welding process variables. Evaluate your current welding parameters and techniques. Help eliminate common welding problems and discontinuities such as those listed below:

Weld Discontinuities
Undercutting
Excessive melt-through
Incomplete fusion
Incomplete joint penetration
Porosity
Weld metal cracks
Heat affected zone cracks



MIG Welding Problems
Heavily oxidized weld deposit
Irregular wire feed
Burnback
Porosity
Unstable arc
Difficult arc starting

Which ones (headers) are TIG and which are MIG?
And would it even matter if done well?

 

Damm Anton... Your in super duper smart mode today

the bling factor is really what makes a difference when you choose TIG.. either way, wouldn't MIG would be required for stronger parts.. like frame? not that it makes TIG unsafe for exhaust, radiators and such..
