Wow I was wrong on that one. Must have been confused with the axially swaged or memory metal fittings.

yea it did suck big time,i gave up a sat and sunday to take the written,and I thought sure the brazing was the easiest part but I was wrong,but I can go and retake just the brazing the next time they are giving the test in an area close to me and im thinkin about paying the 500.00 bucks and try again to get certified to do dentist offices and small systems.i really like running medical gas systems,rather fun I think.at least it was before they changed everything

what percentage silver solder did you use? The last I checked they did not x ray but cut a coupon out and bent it if it cracked you fail. 5% has better flow and fill characteristics you will have better luck with the test.

thanks,yes the 5% is what we used,thing is,i have been brazing for yrs,good at it,we think that since there was 12 of us taking the class,the instructor said at the start,now I promise you all that not all of you will pass this test,and lo and behold 4 of us didn't pass it,last names were 2 beginning with letter b,one in the middle with the letter m,and me with the last name starting with a w.we think that they don't want everybody to pass it that way they can get more money to retake the test,who knows,might have been bad joints,but one of the guys is a certified welder and been brazing for yrs like myself.really aggravating to say the least

yes it is a hard test I too am a certified welder and the 6 g test was easier than the braise test. I found the vertical up the one I didn't like the trick I was taught was to heat small sections evenly and as hot as you can without melting it. If you can't see the silver solder shadow in the red hot fitting.
