Hi all,
Tonight I was given the opportunity to have a tour of a race teams facility.
This is a photo of one of the chassis, they are a controlled component by the racing series and are made from chromoly
I have a question about the “tack” method of mig welding some of the tubes.
When I asked the guide, I was told that they would like to tig everything, but these certain joins are required to be migged, as per the design rules/specifications.
Just wondering if anyone could give any insight as to why these certain joins would need to be migged? As opposed to tig?
And also is the stack of tacks method used due to it being chromoly and needing to control the heat input? Is this a viable technique?
I thought the series of tacks would maybe cause potential failure points, especially with the craters on each?
I will add another zoomed out photo in the comments
Thank you 😁
