A Students Guide on How to Pass a Bend Test

#welddotcom
Today we are going to show you how to pass a bend test with the plate bender we built. If you're a welding student or professional welder chances are you've had to do a guided bend test before. The likelihood that you've failed a bend test is also pretty good. Lots of good welders bust a bend test. because they don't know how to properly prepare the coupons for the test. Did you know that preparing your plates properly can increase your chances of passing a bend test. On the other hand, if you prepare your plates for the bend test improperly, you are setting yourself up for failure! This video is a students guide on how to pass a bend test! So if you are doing your first bend test, good luck!

Im so high bruh im not a welder nor do i plan on being one yet i watched this whole thing

[@SmokinLizzos]

Same brotha

[@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

[@geraldfahey2681]

Ironworkers!

[@Val0rG]

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!

[@metalslingr]

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

[@zeke1eod]

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

[@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.

[@dark30welderwelding11]

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

[@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.

[@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

[@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

[@SteadArcFab_Ministries]

Great video guys! Always learning something! Thanks

[@rickolson9011]

Well planned and well demonstrated!

Awesome work RB!

[@lukasollars6446]

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

[@everlastgenerator]

Always informative 💚

[@leeboudreaux6698]

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

[@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🤣

[@youngjesus5992]

I have a piece I just finished urging yesterday on a 1G. Can’t wait to bend it tomorrow at the welding shop. It’s my second bend test.

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

[@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.

[@khov8980]

Good video . Thank you

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

[@tellshasteen1085]

What soapstone holder are you using? Looks pretty nice.

[@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.

[@thatswhatshesaid3406]

Hell yea brother 🤙🏼

[@delinquentdesign]

Thanks bud

[@trionookto9617]

terima kasih atas pelajaran yang diberikan

Hello can you please make a video on aluminium weld testing. Also the process of test specimen preparation.

[@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?

[@Welddotcom]

Pferd victograin is insane!

[@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.

[@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.

[@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!

[@lowbuckfabrication]

I have one of these coming up

[@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.

[@mitchstephen5491]

Nice trim job on the beard, looking dapper

[@maroonsr20]

all my practice has been open root, don't worry about that backing strip.

[@ledinhanh]

nice video

[@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.

[@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.

[@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

[@Dynioglowy1986]

Im not a welder ... im not planning to weld anything.... but i still watched whole video.

[@luisortega6140]

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

[@mcdanieltslisteningprepara4088]

please sir how can i purchase the hand book you aee use. what is the name of the book. i just started learning welding. your video has been helpful.

[@Michael-qv5qo]

Failed my bend test today all 3 or4 pieces looked good only one failed but ill try again tomarrow

[@treasure_moments]

Awesome

[@sulla1537]

Is this a standard test for welding school?

[@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.

[@pauldiaz4970]

Does temperature matter when it calls for a stronger weld?

[@hooddowntime2143]

I’m not familiar with AWS, but ASME and API 1104 allow corner tears as long as they don’t tie to a discontinuity

Like # 1000! Good info :]

[@mateomontenegro3511]

Could You tell me the book name You are using to explain please?

[@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.

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