good evening sir i would like to have a training in welding, is it possible to turn into a welder, how many years does it take to have a certificate sir please i need help
Just welded my first CWB test this morning. Passed!
effnin A bud. Congrats. Stressful ain't it?
Sir can you tell the whole procedure for obtaining the certification…
Finally been wating for years for a cwb video, only hellNback has only 1 video on it
Finally a real test. I was not allowed any grinders or polishing. Only a hand held wire brush and slag hammer
We were allowed wire wheels on a grinder, inspector just said “it is technically not grinding”
Thank you guys! Been waiting for one of these cwb vids for forever. From personal experience BURN HOT on those root passes Ladies and Gents!
Waited on this for a while. Thanks guys!!
Same here
Good video with plenty of information on foreign qualifications. WeldTube you outdid yourself again! Keep it up👍
Yes make more cwb vids for us canadians
Be nice too see CSA w47.2 aluminum test, using the proper filler and base material. And showing what happens when you do everything right, except the selection of the proper grade aluminum for the base metal.
you should have gone over removing the backing strap and the grinding and the tolerance that allows you to pass everytime
ryan nixon scarfings always fun 😂
If you have to do one of theses tests, find a place that machines off the backing plate(s). Other options for getting the backing plate off in order of least to most endangering your weld are grinding, zip-cutting, plasma, oxy torch (use a jig that’s a right triangle to be able to judge depth of cut) and carbon arc gouging.
Carbon arc the easiest, just look for the line and chase it out
Good and strong welds... what current settings you used for 1G,2G,3G and 4G? And what type of welding rod is that?
cool to finally see some canadian stuff on youtube here. Done this test a few times, always seem to forget my check tests lol
Could you show what a failed test looks like? Failed etch and failed bend.
Beach&BoardFan i think most people already know. Thats why they on youtube looking for help. 😄
Lol true.
I know lots of "welders" that have unfortunately never done a bend test of their welds.
After the bend, if you have a crack that opens more than 3 mm it's a fail. I think you can even fail if it's exactly 3 mm too.
Those root coupons would have failed. That line that is visible from the filet joint side is the original plate material that didn't get properly penetrated into. You can see the he'd have lack of fusion from both the position of his bead in the stop/start visual check, and in the etching process that clearly showed a lack of nugget into that corner.
Rather do all 4 at once, so they can cool in between welds. Save time. At least 2 test at once. But what ever the weld inspector says goes.
w,c,m,w &fab usually they let u do 2 in a day
One at a time.Once you pass the visual,then onto the next position.Bend test are done at the end.
Yeah when I did mine we just banged 4 positions out, inspector looked at them when he needed too, bent them when they cooled
Derek collins yeah thats kinda what i meant by 2 in a day
I have had inspector let me do all 4 at same time .
It should be noted that this is just one method of qualification per CSA47.1. Successfully completing this plate yields a welder qualification for both fillets and grooves in the position in which it was completed (except for the flat groove/fillet plate which gives the welder a flat groove and horizontal fillet qualification). Alternatively, the welder may elect to use a v-groove test assembly which would only qualify them for groove welds in the position tested. The welder would would then have to complete a t-plate test assembly for each position to be qualified for fillets. This is differs from AWS where a groove test qualifies the welder for fillets as well. There are further test assemblies that welders may pursue, but for the most part would result in “non-transferable” qualifications.
Lastly, when evaluating a gf test assembly, two root bends and one face bend are required. No macro-etches are required. And for all processes except GMAW, the test plate may be evaluated by radiography.
Great info.But they also do radiography with gmaw.Bend test is usually the way due to cost.
Great info.But they also can use radiography for gmaw.But almost always use a bend test due to cost.
Derek collins Clause 9.10.1.2 of CSA W47.1 allows for radiographic evaluation of welded test assemblies for all processes except GMAW. The same clause explicitly states that GMAW test plates must be evaluated by bend tests. This is due to the fine grain structure of the GMAW weld deposit, non fusion may not be visible when x-rayed.
When evaluating test plates, typically the labour required to cut and bend test plates costs more then radiography at around 30 plates. But I do have shops that choose x-ray when evaluating as few as 6 plates. I’ve seen as as many as 10 plates shot at once,
@@bman041 I've never heard of that and I'm a C.W.B supervisor.Good to know because we x ray gmaw welds.
Derek collins W59 allows for radiographic inspection of all processes, but W47.1 does not allow for the evaluation of GMAW test plates for welder qualifications using radiography.
I spent 10 years as a CWB supervisor, for the last 3 years I’ve been a retained Welding Engineer for division 2 shops.
What I would like to see someday is the CWB aluminum structural plate test CSA W47.2, i did some practise plates before and was wondering why my base metal was shitting itself before my weld did, I later learned that careful selection of the proper grade aluminum for the bend allowances of the jig was needed.
Just wondering can you get the cwb from u instead of getting your red seal. And if so can u get work with the cwb
I did the bend and etch tests in the 90s when l got my asme 6GR cert,
How did you guys remove the backing?
Easies welding test. I hate all the grinding to clean coupons for bend. Its like a grinding marathon.
Does the U.S. and Australia have similar structural tests? I always thought the CWB basically copied AWS as far a standards except the butchered it into metric lol Nice video guys
I have had multiple AWS cards for different process since 2001. I came across a Certified AWS Welding Inspector that tested the employees at the Company that I work at. The CWI also travels to Canada to test and he told me that the Structural Test is more intense than AWS.
No sir we do not
All my weld tests i assessed had an xray exam only,no cut and macro,no structural stress. Grinders allowed for interpass. No time limit. Straight beads only.
Queenslander.
Awesome video! How about a cwb t class video? 6” schedule 80 on 6g 7018 through out
They don't want to pay for x-ray. Visual is cheaper I guess
Good stuff! Just wondering what you used to cut the backing strip off?
Please do a 1g pipe video rollout wheel. Uphill. That’s what I am practicing
I always gouge my backing strip off before I cut and polish.
I really like to watch such a good job :)
Awesome video!
Can you also teach how welders read blueprints?
3/8 plate 3g with backing strip bend test
This is an FG test. Filet-groove, not a straight groove test.
interesting, but what difference is there between my AWS certs and the CWB? the only things I saw were the inspection of the starts and stops plus a no bevel plate. also my 6g cert covers all the preceding positions... granted I did cert on 3g and 4g stick plus 5g pipe also 3g mig NR232 does the CWB have that one position covers all like the 6g? and when you talk about a buffer wheel do you mean a wire wheel to remove slag ? great vid, appreciate the info =)
Because this is structural welds, I don't think there is "one test" that covers all positions. That would be more so for tube/pipe welding. That is a different certificate in general. CWB doesn't allow you to weld on pressure tube/pipe, only structural. I am not familiar with the AWS certification and what it entails
AWS allows an option for structural plate tests in 2g, either bevel both plates at 22.5 or bevel the top at 45 and leave the bottom plate square. Other than that a plate test is a plate test, the testing body can dictate root gaps and bevels, cleaning methods or the like to suit their needs.
AWS is international, structural steel, aluminum, stainless, sheet and tubing as well as bridge and aerospace. AWS also is the only governing body to handle electrode and filler metal classification and specifications.
madcap magician come to Canada and ur aws certs are not recognized. We dont do 6g tests on structural plate. Lol
Chris Ingram AWS is the American Welding Society and beyond Canada’s recognition of D1.6 for structural welding of Stainless Steel and D1.3 for gauge metal welding, AWS standards are not recognized internationally. As for electrode certification, there are certifications bodies all over the world (including Canada) of which the AWS certification is the least comprehensive. The generic “6010”, “7018”, or ER70S6 designations are now only used in the US.
What gloves James used? Looks good on welding side too :)
Oh this is good. Journeyman welder from British Columbia, Canada here. How is it that I can do my CWB test in a shop that I worked in, and have a carpenter next to me do the same test and we both pass. Carpenter has no interest in welding but has enough skill to pull it off. I went to school and did my practical for 3 years to be a journeyman. I am now in a shop where I have way less competent people next to me but we are all equal according to the CWB.? Guess you can tell I am not a fan of the CWB. Luckily I have moved on to a desk job later in life.
Just because the carpenter doesn’t have any interest in welding doesn’t mean that he is incompetent. I’m a welder in Ontario Canada, i have all my CWB tickets in SMAW, FCAW/MCAW, and I have pressure tickets through the BCA. The proper CWB process is the visual and then gets x-ray. If it passes x-Ray then you’re certified. So obviously that carpenter was competent
Do you have any idea how many guys in this country ONLY have CWB tickets? The only training they have is how to do those tests. Quite often there will be only a single Journeyman in a shop that teaches all the rookies how to do and what to do. Just not the WHY to do.
When employers require CWB certification does it matter if it is done with stick or mig? I noticed most information on CWB testing demonstrates SMAW but I gather from the type of stuff many of these company's are producing it's MIG. They never seem to specify on their adds. Also, as far as bead placement and stop starts are the tests the same for GMAW and SMAW? It's been a while since I've welded and tested..
Apprentice for Canada here. We have different sets of tickets, SMAW and FCAW that are the most common. We need to take separate tests for each of the positions for these and yes the distance and gap is the same asides from horizontal. Horizontal has a tighter gap but asides from that it's pretty much all the same. Hopefully that helped!
Can they see where the 1.5 in line is? Like where to stop to let the inspector check. I mean isn’t it too dark to see with the hood on?
i placed a piece of chalk near the line so i dont forget and go over...i tried the bent 7018 rod resting over the plategap ..but couldnt see it till i was past the stopping point..
I've actually taken a center punch and put a dimple in the backing plate. That little spot shines really well when you get close to it!!
Is this a walking certification
Is it still "G" if it is and fillet and groove or is it "GF" position?
We have one side fillet on side groove so it's gf flat, vertical, overhead is half inch gap, horizontal is 5/16" gap
@@roadkillfrog5591 Where I come from it is still called a 1G, 2G, 3G, 4G (when you have both a groove and a fillet), but it qualifies you for both the Groove and Fillet, as opposed to doing a test for each
These plate tests are called FG's. The weld is called a Filet-Groove as you weld the filet side first, then the fill in the resulting groove weld. The weld position nomenclature stays the same though.
The Bend test need to be done at certified lab?
No, Just with a certified testing individual. As it is, those plates would have failed!!!
That line in those root bend tests would be a failed test. You are allowed UP TO 1/8" of faults(cracks, lack of fusions, slag inclusions, etc...) in the test coupon. If you can see the entire line of the original plate, that's a fail!!!
i thought maybe that was backer that they didnt grind completely off.....but i noticed that too.
I need cwb certificate
I'm form Bangladesh.
I have a question guys, if i was from another country (Australia) and had my pipe and pressure vessel ticket from AUS could i Certify in Canada for structural or a pipe pressure ticket straight away or would i have to go through a training program like GRB collage of welding has first ?
Thank you
You would have to get re-tested of course.But yes,you could certify to do it anytime.
Yes,you could re-test and certify without a training program.
@@derekcollins1972 Thanks
Great info!Tell to Travis to speak a little slow motion😄!He speak too fast!Oiga hablo español 😂😂👆
interesting to see the difference in tests. a little fast but ill watch it over again.
Yo!
Fantastic welds boys, Quick question can y Weld m'y 3g at 100 amps and set m'y Dig at 7 thnx? IW711
If you are using 1/8 rod try 115-120 A with a 50 dig and don't forget to let your plate cool for a bit before you cap. (this worked for me and i passed the first time)
👏
I wan learn in your school
I love this work very much sir please sir can you help me get it?
Requieren soldadores 6g. Smaw , fcaw
I am welder 6g.
Hay trabajo para soldadores 6g. Smaw, fcaw
I didn't know Canadians have a Aussie accent?
