It's called TIG welding, a variant of the many types of arc welding. Search google for the acronym.. I don't really remember anymore.

Hi All Si fu,
Is the twin-loop muffler suitable for D series with Auto Tranny SR4? i scare if i apply it i will lose power or else nothing diffrent from my stock muffler. I found a clone twin loop muffer cost about RM460 with installation. I also notice the muffler welding is look like you all so call "TIG welding"

So all the Si Fu please give some expertise advice.

Million Thanks.

Hmm.. nice extractors for the first pic.. c'mon.. don't leave us guessing.. what brand/model?

For the second pic.
Yup.. nice welds.. less on the strength factor, since it's spaced further apart... but still nice clean welds.

[hattech-v]

mig29-n i know laa... kekekeke

tigs have both kinds.. one is that they use extra material for the welds, and another is they use the material from the thing they want to join for it.. That's why got some TIG welds sink into the material, and some doesn't. TIG welds are concave in nature.

MIG welds are usually rounded. You can see most taiwan bicycles using this kind of weld. it pops out from the surface. Sometimes good ones look like TIG, but they are convex in nature.
