Good morning. Can anyone help me on how to do a costing for welding works of a flange to weld on a GI pipe. Thanks

Hello,
Well as far as the cost is given by welding in / diametrical, suppose you have three joints 6 ": 6" x3 = 18 in / diametrical x "unit by joint"

Shop?
Field?
What kind of welding? GTAW, GMAW, SMAW?
How big a weld is needed? Single pass or multiple passes?
How big a pipe and flange?
What kind of flange: SO, Weld neck, already fitted up?
How experienced a welder?
Working from a jig waist-high downhand with a rotating mount, or free-hand, or from a vise in a fixed angle, or up in scaffolding or on a ladder with a harness in the big middle of nowhere?
One-of-a-kind fabrication, including fitting it up and establishing a purge?
Or on an assembly line where he (she?) makes 15 an hour? Or makes 5 an hour, but only twice a year so the welder never gets experience and repetition?
