i dont know anything about welding. whats the diffrence between a mig and a tig weld? also is there a video or something i can buy to learn? im still in high school and i cant take the welding class cuz im senior and its to late. and i cant go to a community collage cuz i need my high school diploma so i whanted to learn right but somewhere other then high school or collage. let me know where i can buy a video if theres any.thanx

Heres where the main difference lays:

MIG uses a gun that energy and wire are constantly coming out of depending on how much of each you adjust at the welder.

TIG has seperate energy and filler material (wire). You can control each one independantly from each other, giving you much more control over the finished product. Also add a lot more time learning how to do it correctly...

Either can be used in a lot of applications, although I personally would not want to seam weld a chasis with a TIG, nor make a set of headers with a MIG. Depends on what you want to do (realistically).

main difference...MIG is the easiest method of welding while TIG is the hardest..

IMO Tig welding is the easiest welding. You have so much more control with it. You can control everything while welding and with all the control variables it can't be beat. Over in japn alot of the tuner shops seam weld their race cars with TIg welders. I'd much rather do it that way, but i don't trust MIG welders so thats just my .02

 

Use them both and I like TIG. Much cleaner.

 

both are wire feeding type welders. you have a gun in your hand that auto feeds wire as u pull the trigger. MIG uses amperage to adjust your welding characteristics. TIG uses voltage to adjust that. TIG has a C02 tank of gas that you use simultaneously as you weld, while MIG doesn't need a gas ( i think). MIG welders are typically cheaper around the 300-600 range. TIG are about 700-1500. TIG makes nicer welds than MIG, but are slightly slower. MIG and arc welding is faster. MIG welding is a bit less accurate and more sloppier than TIG. TIG has more penetration than MIG. TIG are preferred over MIG in applications where structural and strength is important.

correction:i was talking about the gun type TIG welders. i know there are some TIG welders where the technique is almost like oxyacetylene welding, but we used that only to weld aluminum becuase you can use the pedal to control the heat. if you were referring to the gas welding type TIG, then YES it is VERY HARD! especially with aluminum.

tekstyle-your comment confused me alot*...tig is based upon a "gun" to send the electricty to the metal which upon welding...the rod that is placed-usaully in hand-at an angle to the metal is what melts down...the Tungsten electrode is nonconsumable...MIG uses gas with "gas" wire...fluxed core wire(kinda like solder) us used without gas.

sorry. i am just recalling experience from my class. the MIG welder we used didnt have a gas tank next to it, but the wire might have been self-fluxed. we had 2 different TIG welding machines. one is the "gun" type you are talking about and those had a tank of c02 to shield it. the other machine used tungsten electrode, a pedal controller, and rods to weld. there was also a tank of gas, but i don't think i used it when welding aluminum.

Great link, the pics help out a lot.

 

does anybody know which weld would be better and stronger for chassis welding?

Weld is weld so long as its done correctly. Main point being, its easier to use a MIG with less experience and produce a good weld... its MUCH harder to produce a TIG weld of equal quality without the experience to boot.

Personally, seam welding = MIG, roll-cage = TIG

Unless your building a tube chasis or using parts that require EXACT temps, tollerances, etc it would make little to no difference using either MIG or TIG.

If you were Tig welding aluminum correctly you would be using a shielding gas.

 

Aluminum has to be spotless for it to weld good...oh and TIG...Tungsten Inert Gas...TIG..yes if you did it you used gas...if you didnt ..you messed up...

You are talking about MIG welding. *** with no gas is fluxcore MIG. Spool gun or pull type welders are MIG welders also. they are usually used for AL because the wire is so thin and can break easily. They also have push/pull setups for MIG welding. Everything you described is MIG welding.

TIG welding you manually feed the filler material. And with TIG you want pure Argon for it. CO2/argon mix is a nono Oh and if you didn't use the gas while TIG welding you fugged up Aluminum or not. You need the shielding gas!!!
