A Students Guide on How to Pass a Bend Test

[@grandolph9281]

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!

[@dark30welderwelding11]

Agreed lots of people do not understand the metallurgy, math and physics that goes into each weld.

[@ok2full]

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

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!

[@Welddotcom]

Thanks for watching

[@gnarwhalsw8296]

Our bending machine at school also has a sign hanging from it that says "heart breaker" how funny lol

[@metalslingr]

Yep. All of that instruction was totally consistent with my training. The bend prep details are vital!

[@jseekell]

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. 🤦🏻‍♂️

[@desyquintero8451]

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 !

[@xXxXcrosbykidXxXx]

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.

[@casey360360]

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.

[@shotit-df7id]

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

[@sulla1537]

Is this an advanced test or standard for a welding school?

[@mooseworks]

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🤣

[@carolshawol6699]

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

[@Welddotcom]

Glad to help 👍

[@donpizzo8963]

What an awesome oxy/acetylene cutting skill!

[@jasonbecker3362]

Thank you, I do what I can.

[@sspp3065]

cutting,beveling and washing is as much of a skill as welding.

[@gnarwhalsw8296]

Yeah no doubt that was a low key flex lol

[@justinmartinez680]

Good timing I just passed an 4g overhead bend test and 3g vert up open root bend test

[@gregmancilla]

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

[@lukasollars6446]

Great in depth explanation. I watched because I’m about to take my first bend test in a few weeks.

[@Kevin.L_]

The welding was easy. Test prep was the hard part. I have very little torch experience and we had to cut backing strap off with the torch.

[@leeboudreaux6698]

I busted out a test because of grinding wrong years back. Does make a difference. Great video.

[@ee233]

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

[@ProtossBossSauce]

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,

[@seanlavelle344]

Thanks I'll try this out so I don't have to carbon arc gouge my test plates.

[@BrazilWeldsMessiasCarvalho]

Very, very informative video my friend!!

[@1960jelliott]

Great explanation for our students at Lee College Baytown Tx.

[@texasplumr]

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.

[@that1honkydrew]

What kind of disks were they?

Nice now to start the bend test iPhone 6 Plus is required

[@Konzeptionz]

If you pause at 17:15, you can see the second one fractured, but was stealthily replaced for the next shot.

[@jamesteak6510]

"stealthily" bruh you hear it break and clearly see it

[@consciouslytrying5357]

I saw that too 😅

[@johnsherman218]

This is the most informative video on testing. Thanks

[@thee_number_six6227]

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

[@grigoriyefimovichrasputin7897]

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.

[@dark30welderwelding11]

Thank you for taking the time and care to explain so well. Much appreciated

[@VortekXtiik]

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.

[@TheBekasoo]

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.

[@johnshufflebarger9817]

I would have liked to have this info before I did all my bend tests especially my finals ..

[@timothyberry9084]

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

[@justinhembree351]

I iron worked for a while and I picked up on simple welding very quickly however I’d like to understand how to do better.

[@kennystroner7431]

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!

[@metalheartmachine]

Doesn't flame cutting potentially alter the characteristics of the metal in the test?

[@phiksit]

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

[@LilFish0]

[@Jared-xf5xl]

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

[@rickolson9011]

Well planned and well demonstrated!

[@stevenslater2669]

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.

[@BadEconomyOfficial]

The BIGGEST thing when it comes to a weld test NEVER cool down the plates, it’ll weaken the metal.

How to carryout the bend test for Titanium alloy (Gr.5) material?

[@joseHernandez-uu2cx]

Where i can find the video how to make the press to bend? Thanks

[@AzzKicker-bz1cb]

@Weld.com I have put a slight reverse bend in my plates after doing the tack weld(mostly on open root) so that when the heat of the welds start to pull the pieces inward to the center, it actually pulls them flat. Does that eliminate those coupons from a test parameter? I have other issues with welding to pass bend tests that would not be associated with the previous question. I’m trying to figure out what I need to do to get to the point of actually being able to pass bend tests.

[@CTSCAPER]

Really great video. I just looked up the Pferd CC Grind. The literature says it's 50 percent quieter. Do you notice a difference in the noise level?

[@jasonbecker3362]

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.

[@dolphincliffs8864]

Yep,quieter.

[@pykerocks]

Hey love the videos very helpful.just curious what brand are those gloves you're wearing

[@dominicdimartino5005]

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.

[@luisortega6140]

What kind of gloves are those for when you were handling and prepping the coupon

Do you have to bend it all the way to test the weld?

[@georgematthews3222]

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 never understood the backing plate, does it not fuse to the weld?

[@samnottheotherone4363]

A steel backing plate will fuse into the weld and in the field will either be ground off or left on depending on the specs. Copper or ceramic backing will peel off.
