In this video I debunk the myth that the correct way to make splice joints in chassis members is with an inclined or Z cut. These are scarf joints which have been used for centuries in timber structures but have no place in welded steel structures. I also address the supposed regulatory requirements about this which apply in certain parts of the world. Of necessity this is a technical video although I have tried to make the concepts understandable to non-engineers. This is a re-posted video with the new content appearing at 16.30. This video builds on ideas introduced in my earlier video on chassis repairs (please watch this first) https://youtu.be/V-9QECXkPTg Those who want to learn more about the methods used in this video are encouraged to look at the following videos: Beam stresses https://www.youtube.com/watch?v=f08Y39UiC-o&t=203s Mohr's circle https://www.youtube.com/watch?v=eVxwcehWYyU&t=284s Failure theories https://www.youtube.com/watch?v=xkbQnBAOFEg&t=682s Mohr's circle and failure theories https://www.youtube.com/watch?v=EtTAUkOB5z4
