Mr. TIG simulates the welding of Stainless Steel headers and other components found in exhaust systems. He also talks about how to choose the right Stainless for your application, which filler material to use, and why it is important to have good gas coverage (on both the front and back of the weld)
The Setup:
Wyatt starts off by going over some basics on material selection for headers and exhaust systems. He talks about the use of 304L on many day to day stainless exhausts and headers. He then talks about why you want to upgrade to 321 Stainless in applications where you will be using it for several hundred miles at high temperatures (racing temperatures).
After talking about the materials that he is using in the application, Wyatt goes into how to purge the weld with inexpensive materials to get the best possible results.
The Welding:
After purging the tubing, Wyatt welds up half of the application. In order to show you how important it is to get good gas coverage, he does not purge the backside for the second half of the weld. After both welds are finished (purged and un-purged) we take the sample to the lab, cut it in half, and by the miracle of TV magic you can see a cross section of the purged vs. un-purged Stainless!
Bonus Footage - Cleaning the Weld Electronically:
