Exhaust welding

TIG welded the tube work of the exhaust.

I love stainless...   leave it bare and it won't rust! And welds will stay colourfull. I used Solar Flux type B to shield the inside of the weld.

Mild steel, and it's rusty already! The last section of the exhaust (the pipes over the diff to the rear of the car) is mild steel. Stainless can sound a bit 'tinny' apparently, and I want a more mellow/deep sound. I save a bit of money too. These will be sandblasted and painted in high temp black paint, then the bends will be wrapped with thermal wrap where they pass by the shocks and gas tank (mainly 'cause I have some unused wrap, and because it'll look cool).


  1. You’re a pretty good welder. The welded area is very clean and perfectly done. I can’t even see any mess or hotspot in the stainless steel. Kudos on your well done welding project!

  5. Electric resistance welding
    The world owes the invention of electric resistance and spot welding to Englishman Elihu Thomson. This engineer has several patents in the field of spot welding to his name.

    Electric resistance welding consists in assembling by autogenous fusion the parts to be welded under the pressure of two metal parts. Who says welding says heat, with resistance welding the heat necessary for welding is provided by the Joule effect (which is the thermal manifestation of electrical resistance, this heat occurs when an electric current passes through any material conductor) of a current of high intensity and low voltage, passing through the parts to be assembled. Indeed, it takes a lot of amps and little voltage. The application of a forging force makes it possible to ensure the metallic interpenetration.


  6. Just travelling online for hunting information of steel supply melbourne for getting our residential still products and while scrolling my pointer down on the browser, I was lucky enough to discover your quality demonstration. That's really amazing. I like the way you unfolded all the information related to exhaust welding.
