May 14, 2007 · Best test to give them is a hands on. A branch test layout is a good one to try. Just give them a piece of 12" pipe and ask them to layout there saddle cut to 90 degree branch onto another 12" pipe, no actual cutting or welding needed to see if the person can fit pipe.

Dec 22, 2010 · The ammount of rejectable weld that would result in termination would vary by the application (a structural welder would have more allowable than a pipe welder for example) and this would have to be communicated to the welder upon successful completion of their weld test.

Oct 21, 2007 · The welder is tested with the gas company but normally works for an independent contractor. The contractor will employ a fitter/helper that the welder provides who can help with the fit on the branch part of the test. I have taken many tests as a fitter/helper for the same welder and we have always done well.

Feb 28, 2009 · Hi Friends I've asked similar question in different form. AWS D1.1-2008-Fig. 4.27 test position used for 6GR Welder Qualification.Table 4.10-Under "Production Pipe Welding Qualified" Column limits qualifcation range with Note "d".Root run done with LB52U + Fill/Cap with LB52 Due to this limitation, basically 6GR NOT qualified for pipe welding where internal access not possible for backgouging.

Mar 19, 2015 · Going to take the CWI test in August (Chicago) one of my goals in life - Been around welding as a welder, supervisor (Have had 5- certifications in the past) and as an engineer for 30+ yrs. I have 4+ months to prepare. What is your recommendation(s), reading, studying, etc. Books to purchase. I have D1.1 (2004) Structural welding code book (1996).

Dec 9, 2010 · Hey guys, The Pipe Fabricators Blue Book by W.V.Graves is also a good one to have By rcwelding Date 12-10-2010 02:18 Edited 12-10-2010 15:22 Thanks Allan...I have the black book by Frankland but I had never used or seen the blue book...

May 31, 2008 · Pipefitters welds usually look very good (see jackstand above) Fitting pipe takes 1)technical skill and knowledge, some tools for precision alignment, and some strategically located tacks. Fitting for boilers takes comealongs, chainfalls, ropes twisted around tubes, wooden and steel wedges, and at least one "HURRY UP NAIL IT !"

Feb 6, 2007 · The one you might be thinking of and the one I find very valuable is " THE PIPE FITTER'S AND PIPE WELDERS HANDBOOK" by Thomas W. Frankland. It is black and about that size. Some of the concepts are much easier to understand and has alot of useful formulas and such. Welding stores usually have them also.Henry

Nov 12, 2010 · Hope it helps some. Best regards, Allan Edit: I have included another JPG of the dissimilar diameter layout procedure for on-center pipe. Off-center pipe would require doubling of the required measuring points and is definitely a bit more involved. Have included an off-center dissimilar diameter JPG. for those who might be interested.

Oct 27, 2014 · You won't find it 1104. That is usually in contract documents. Now, depending on how the welding procedure was written, it may be necessary to use two welders to maintain minimum time between passes to avoid a preheat maintenance process, which are required variables in the WPS to API 1104 (minimum time lapse between root and first fill pass - essential variable, minimum time lapse between ...
