As hack hobbyist I have been watching this channel to learn some basics and for its entertainment value (almost every video is good for a laugh or two). But have to say, you guys have also given me a new found respect for the profession of welding, a combination of technical expertise and craftsmanship. Well done and kudos to all the true welding professionals out there!
yessir. as i always tell the kids who think they are hot shots out of highschool just because you can make a pretty weld doesnt mean its a good weld. the amount of time it takes to become even novice is several thousand hours under the hood
I'm a third year local 40 ironworker (nyc) third year apprentice learning welding and this channel has been the best for me to learn welding. Thank you for doing what you do!
Yeah, don’t quench! 😂 I made that mistake once. I picked up my strip after leaving it to cool but it was still super hot. Out of reaction I chucked it in the nearest tub of water. I went to bend my two pieces, neither of which had visible porosity, but the one that was accidentally quenched split right in half! Good thing it was just for practice. 🤦🏻♂️
So interesting how every metal needs its own procedures. I'm a jeweler and we often get fits with white gold cracking so while visiting a metallurgist friend that does high production castings he told me, "quench white gold right away and it won't crack" Guess what he was right !
Little late but maybe it'll help somebody.. if you happen to accidentally or mistakenly quench your plate or coupons, you can reheat them with a torch then allow them to cool naturally and they will be good to go again! I've dropped a plate in a tank by accident while setting up to cut it with a torch, just get the weld zone cherried again and it will be fine.
Excellent tutorial even for us old heads lol. I will never forget my 1st bend test in the ol "heartbreaker" 1993 wow where does time go! Thanks for sharing, God bless!
I built one of the benders using the specs you used same press from harbor frieght don't have the air Jack just the pump but I've been welding plates and bending like crazy so glad you put that episode out
I always find myself watching these and thinking "That's honestly no more difficult than welds I've done out in the field." Yet I still get over the "test jitters" that come before a test. I've been welding for 4 years and still can't seem to walk my happy butt into the test.
As a welded structures design engineer who defines the usage of AWS D14.4 and D1.1 on the drawings, these types of videos give me a massive appreciation for the guys actually putting the structures together. The skill/workmanship that is required and verified with tests like this excite me to want to define welds that will result in high quality welds leading to long lasting structures. Kind of makes me want to try the qualification test myself as a non-welder and see how bad thing turn out. haha🤣
The weld shop has been closed most of this year so studying this channel during quarantine literally prepped me for my test , I am testing next week💪🏼 433
A great way to remove a backer is this, Cut your strips, Use a zip disk to notch into the MIDDLE of the backer and go down 3/4 of the backer. you now have a line scored in the backer but not into the test piece. Then put your backer in a Vise and twist. the backer will split and be easily removed by hand. then minimal grinding is needed,
Fantastic, I was just googling how to prep a plate with backing for a bend today. Now I don’t have a press or anything I was planning on just strapping it into a vice and using a pipe to bend it. Maybe too crude, but again this is just what I have access to. Thanks, happy Memorial Day
Grinding the material induces a strain hardening at that location . This rises the shear stress required to rapture the material and consequently draw sort of unreliability in final results.
i would love a t/shirt but with this virus shipping is taking nearly 4-6months to Oz,when airlines are flying more frequently then i will consider it. Thankyou for doing this channel it is sooooogood for a beginner,also being a f.Love it
I just ordered two of those grinding disks on Amazon. Damn man! I've never had disks hold up like that before! A little spendy but will hopefully pay for themselves through longevity. I'm going to find out.
Hopefully I pass my Bend test tomarrow for my job interview my pay rate depends on it I'm getting nervous 😅 Its been a year since I graduated college and that's the last time I welded I passed my Bend tests in college but damn jobs make my nerves go crazy
I never used backing strips on my bend tests back in vocational school passed on my second test. Root passed both times face on the first was bad. Used a track torch to cut the bevel on my test metal. Cut the test pieces on the band-saw
I didn't use a strip either Id tack it at the ends so i can then tack it standing on another plate to my table then fill the root letting the arc fill in before i push it through then made the face with stringers 2 on the root pass then 3 over the last two stringers bottom to top with all 5 passes then grinded.
Would you ever do a CWB F class ticket video? Different than the S class quite a bit, The test consists of a 6010 open root with 7018 hot pass, fill and cap also with 7018. Then you also complete a fillet weld break test. Certifies you for open root and fillet welds. It is a common procedure you need in pile driving, as sometimes you will have to splice piles with a 6010 open root.
ok I am having problems with my weld test were the I have done it 5 different times and I have passed 1 but these teacher keep feeling me due to micro-cracks and it is pissing me off
I was wondering. The reason you don't want to put it in cool water is just because to avoid warping and cracking of the material? I watched your whole video. Very informative. Boy, do I have some work ahead of me to get that good!
Sure made a lot of extra work on my recent failed tests :( And the instructor wanted every ENTIRE coupon (four) ground entirely clean, with no vise to hold it and a worn ass grinding disk... sigh
Man I just can't get my damn welds to look as good as these..the past few weeks at school have been very discouraging for me. I'm having such a hard time passing my bends. To the point where I'm starting to question if I chose the right path. I'm pretty damn good at Flux and MIG, but anyone can be good at those procedures.
Not sure what asme standard you are work in to but you should not oxy/acetylene cut weld test coupons ,you should use a band or mechanical saw to do the cutting of test coupon, the heat of the flame will effect the mechanical properties of the weld, could go on but enough said the rest of he vid was ok
i like to blame my failures on lack of coupon preperation. i told my instructor that my lack of prep caused my busted test. ive never seen a bigger eye roll lol
So much for the “common knowledge” that a weld joint is brittle! Are there welder certification requirements for tensile testing? I’d like to see if the tensile failure point is in the parent metal, or at the fusion point of weld material to parent metal.
Txs for this great video…I’m starting my Students on this test….how would you recommend building up their skills to that level..what are the defects permissible….cheers Norm
I need some serious help, I did a 7018 open butt, I did a root pass with a 6010 in a 1/4 inch groove and filled it in with a 7018 1/8th rod. I back gouged the back but messed up on the gouge and now I have two gouges and they are messy. Should I fill up both gouges? Or just start over
Definitely, although I still recommend wearing hearing protection. It’s more of a loud scraping than a grinding noise. And it takes off mill scale with the quickness.
