There are fitting hand books that give you all the dimensions and exact measurements for all your cut backs. It takes a little practice but the books usually tell you how to do it step by step. However the real reason a test like that is given is often more about watching how you go about the process of making it. It's an intense lay out job. If your not super carefull about measuring and cutting out the pieces you get bit in the butt when it comes time to weld it together.

first let me introduce myself I am Allen from south east Ohio have been following Jody for quite sometime this is my first reply so please bear with me. I owned and operated my own welding business doing any thing from pipe fitting x ray on gas compressors to some of the nastiest heavy machinery repair there is. Do a lot of old school SMAW,FCAW,GMAW,TIGW,along with torch,plasma,and oxygen lance cutting. After 40+years of this I am now being forced to set back look at a worn out body but maybe able to pass on some advice good or bad. Now for my reply. U Tube has an excellent vidio just type in laying out 12ingh branch real pipe welder doing real welding.

Welcome to both of you...
I was too preoccupied to catch it at the time, but you both managed to post in "How to use the forum," which is intended as a user guide. You'll note I've moved the topic to "Member introductions", as that seemed appropriate.
Enjoy your time here. You'll find nothing but honest folk who will share what they do and help if they can.
