Welding Titanium, as we now know from our other Titanium episodes, can be a very difficult materials to weld. This is why we were invited to Jay Leno's Garage to help General Manager, Bernard Juchli with his Formula One sidecar build. This is the first of a two part series where we will be fabricating and welding an exhuast system made of Titanium and Stainless Steel.

In this episode we will show you the project and describe what needs to be done. You will see how we set up the gas and purge the backside for welding Titanium. You will then see how we go about cutting and welding the exhaust so it works for the new build.

Many people think that it is not possible to weld dis-similar metals together with full strength. Well, in some ways that is true, but it all depends on how you look at it. In this episode of TIG Time we are going to weld 1018 mild Steel to 309 Stainless Steel with "full strength". Now when we say full strength, you always have to downgrade your properties to the weaker of the two metals, in this case the 1018 Steel.

Be sure you choose the correct filler material to insure you are getting the best possible properties out of your weld. Click this link to download the chart: Stainless Steel Filler Selection Chart
