you have me totally lost
24" ID pipe???????


large pipe is measured by OD

wall thickness is 4.9"??????


24" OD pipe sch 160 is 2.343" on my tables

and that on my tables is the thickest std pipe size
the groove angle of 60 degrees sounds large to me
this sounds like a school question
or to bid a job
and need way more info for a job bid
and the correct info

start with welding process
then manual


or robotic?
but I think you should go smaw 1/4" 7024


and make at least 80 man hours out of the job


and how many passes? ALOT

sincerely,
Kent
