On comptechs website they have a TIG and a MIG welded header....


there is a price difference but is there a performance difference?

sorry if this question has been repeated but i did a search and nothing came up.

Thanxs in advance!

 

What is MIG Welding?

MIG stands for Metal Inert Gas welding, many times called Wire-feed.. Also referred as GMAW (Gas Metal Arc Welding). The "Metal" refers to the wire which is what is used to start the arc. It is shielded by inert gas and the feeding wire also acts as the filler rod. A semi-automatic process, it is fairly easy to learn and use.


What is TIG Welding?

TIG stands for Tungsten Inert Gas welding. Also called GTAW (Gas Tungsten Arc Welding) and Heliarc® which was Linde's trade name for the TIG process when it was introduced many years ago. The arc is started with a tungsten electrode shielded by inert gas and filler rod is fed into the weld puddle separately. A slower process than MIG, it produces a more precise weld and can be used at lower amperages for thinner metal and can be used on exotic metals. TIG does require quite a bit more time than MIG to learn. It is similar in technique to gas welding.

Summary: TIG is better than MIG.

 

so since it takes them more time to make the tig header....and time=money.
it cost an extra hundred bucks.
both have their warranty though, and both are street legal.

 

thank you for explaining the difference.... so basically no performance gain just quality?

 

not even quality, the looks in my opinion.. welder defines quality

 

its quality also. hte welder plays a large part in quality if the welds...but so does the type of weld used.
the tig is also polished stainless while the mig is burmished stainless.

 

wow...thats some good info someones been taking their basic metal 101 i see.

 

are there any performance differences between the GSR and the ITR model?

 

fitment, gsr exhaust/cat is different lenght

 

so how is that quality, other than cosmetic? i sure would choose tig over mig if option offered, but only cause it looks bling bling.

performance from a weld???

TIG is stronger AND nicer to look at.

 

TIG results in a smaller weld bead but takes a very good welder. it takes appro 30% longer to do than a mig weld. TIG welds are used in aerospace, indycar and other sportscar welds. it is the strongest weld available and also the cleanest when done correctly.
