    Two intersecting tubes | 
  2018-08-15 | 
   
    | 
  From Tommy: Hi, I am trying to determine a mathematical model for two metal tubes joining at various degrees for weld.  
For instance, if I am trying to join the end of a tube to the side of another at a 90 degree angle, it will be a simple profile cut out of the joining tube. 
Where it gets tricky is if you want to join the new tube at a given angle.   
It would be very helpful if you could give insight as to how I can solve this problem or an equation I could work off of. 
Thanks for the help!! Answered by Edward Doolittle. |
