Re: 14, X-52 pipe joint

>How long a 14", X-52, ERW pipe joint would normally take in welding?
Check with your consumable supplier to see what the deposition rate is. Lincoln Electric for one has excellent information on their web site.

Deposition rate is the starting point. You need to know how many passes are required, and the 'operating factor' which reflects time required which isn't actually spent depositing weld. It's a number less than one which divides into the 'arc time' when the welder is actually laying down metal. It'll vary between 0.2 and 0.6 for manual welding and accounts for fit-up, tacking, changing electrodes and clean up. 'The Procedure Handbook of Arc Welding' by Lincoln Electric has some pretty good guidance.
