The correct way to make welded splice joints in chassis members - WITH MATHS!

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 video builds on ideas introduced in my earlier video on chassis repairs (please watch this first)    • Rustproofing and chassis repair pt.3 - cha...   Those who want to learn more about the methods used in this video are encouraged to look at the following videos: Beam stresses    • Understanding Stresses in Beams   Mohr's circle    • 08.2 Mohr's circle for plane stress transf...   Failure theories    • Understanding Failure Theories (Tresca, vo...   Mohr's circle and failure theories    • Yield Criteria for Ductile Material
