Welding
 

is gas welding the best form of welding for auto applications and general car work or is arc welding sufficiant? I never figured out the difference in benfits between the two I just know that with gas you can also cut, and with arc just weld. Can someone give me some basic 101 on this topic

Arc welding is one of the strongest forms of welding and is used on something you want to have some real structural integrity but if your welding something like a custom intake,downpipe,turbo manifold I'd tig weld it because it is also a very strong weld and it also looks really good if done by someone who knows what there doing.

it depends on the metel that you plan to weld, tig is for aluminum, Arc is for slightly thicker metels from about 14guage up, not sheet metel. mig is the most common for our vehicles , it is good for nice looking beads on exaust or rollcages. It also works great on thinner guages of metal because you can turn the heat down so low and still get good penatration. Oxy acteline, or gas welding is great for thin metal and precision welds, also for brazing. and with the right tips can be used in cutting and bending metal.

Well first of all what are you welding if it is a frame, i would use arc(stick). Welding if it is intake i would use tig. If it is body or exhaust i would use mig. I dont know what the others that have posted have for a back ground but, I am a welder for a fab shop and when to collage for autobody. As far as gas welding and brasing they are old school now and not realy used cus they have little strangth.

TIG is not only for aluminum...its also for high carbon steel, stainless steel, or just cold rolled steel. TIG is used for high precise welds with excellent penetration and strength. Plus its user-controlled, means you controll the heat, gas flow, and the filler material, thus making a fine, precise, clean weld. MIG does not give the nice looking beads people see. Alot of people who fab exhausts, roll cages, intake pipes and etc use tig for the above reasons that i just stated. Also, if you dont catagorize 14g as sheet metal, you might want to hit the books again, and stop posting incorrect info.
