slipon Flange welding
(OP)
I want to write a preliminary wps for flange (MS thickness 20mm) to a pipe ( MS thickness 8mm), i was referring to D10.12M/D10.12:2000, Guide for Welding Mild Steel Pipe. but there is no information on fillet weld. Do we have to run tensile and bend test on test coupon?

But writing a procedure is not easy if you do not have any experience, I suggest you look for advise. If Code work your inspector can help you. Also look for AWS standard welding specifications.

Weld size is per Code, so what Code are you using? Typically, the throat of the fillet has to equal or exceed the wall thickness of the pipe, making the filletweld leg size 1.4 times wall thickness [square root of 2; 45° right triangle]. Thus the amount of weld on a heavy-wall flange is huge; 3/4" minimum on an 8"NPS Sch80/XS pipe. Thus the preference for weld-neck flanges.
