The 20th Edition states:
Branch Weld - The completed weld joining a branch pipe or branch fittings to a run of pipe.
Just FYI, it is a little different. What edition do you have SectionIX?
Thanks SectionIX but the olets that we use here are full penetration welds. They are 'set-on' the pipe, required to have a gap and SHALL completely penetrate the weld... I'll look into the fillet weld requiremens though for 1104.
That's what I'm talkin about Sec IX! So, again, WPS and a Coupon Test Report should be sufficient? Also, what welding procedure do weldolets fall under? Do I need a WPS for 1/2" - 2 3/8" branch connections just for them or would they go under the procedure for the pipe they are actually going on?
I've read this but it doesn't specify a "PQR" and "WPS". What I am gathering is that you basically need a WPS with a test coupon report that proves the WPS. Sec IX on the other hand states both are required.... Do you see what I'm saying?
Can anyone share the section in API 1104 that states that you have to have a PQR and a WPS for a legal welding procedure? Would a WPS and procedure test coupons be OK?
When testing welder to API 1104, is the material an essential variable? Can I give them a 12" butt and branch test with Grade B STD wall pipe, 6010 downhill all the way and they be good for all thicknesses and diameters and grades? The reason why I'm asking is we are welding Grade B pipe all...
