?s about bend tests for certification and making a tester.

At my new job where I am not a welder and had no knowledge of these tests I need to build a tester and get the correct tooling. The boss wanted to be able to test up to 1 in thick material but I find nothing in the book(Vol 9 of the standards book) on doing these tests on anything thicker than 3/8s.

  1. has anyone ever tested any material thicker than 3/8? Another thing is the dimensions for the punch and female part of the jig vary with what "P#" the material is classified in.
  2. What is different about material of the same thickness that the jig would have to be different? What I have come up with is using a 20 ton bottle jack on Channel with welded channel sides and top. The Male section fits above and its all made so if I hae to make different jigs they go in the press easily.

The standard bend tester is a simple jig that can be placed in a larger hydraulic press or built as a single purpose device.

The Bend jig is identical to what we use in Washington state for the local WABO welding certs.

Here is the PDF file that has all the info.

formatting link
It is a 73 page document, but gives a good overview of weld testing. It describes the common 3/8" and 1" plate tests and how to carry them out.

The useful stuff starts on Page 25, and the jig specs are on page 49

I am a AWS Certified Weld Inspector and I built my own bend test jig last year. I built mine with rollers, but the solid steel ones work fine.

WABO is based on AWS D1.1 from about 20 years ago. Little has changed.

Thanks -there is a lot of good info in there. I'm waiting on material not to make the bend tester.

If you contact the American Welding Society, they can get you in touch with your local section. Somebody in the section has the Section Library where you can go and look up AWS B2.1 Fig's II-5A and II-5B. Each section is able to maintain a library of all the AWS specifications and you should be able to get what you need through them. Some sectinons have actually worked through their state association of Libraries and locate the Section Library at a local library that can ship the books to anybody in the state with a library card.

You might also try your local library, maybe they have a faster computer link and you can download the Washington Association of Building Officials Standard there.

Sorry I have had High Speed DSL for so many years that I tend to forget about dialup speeds.

You can contact WABo and for a fee they will send you a copy of the

27-13 Spec.

I know it is a large file. My old computer couldn't even handle printing the whole thing. I had to print it in sections.

I have tried to down load the file - I have ADSL and it is an ok but night or day the file gets to about page 30 and then Adobe says there is a bad page and aborts. The first 20 so pages come fast and then it slows down - and then halts. I suspect timeouts are happening or the file is to large for long network of varying file size allowances - perhaps...

Try altering your settings so that you are simply downloading the file, not downloading it into acrobat/adobe reader and viewing it as it downloads. The latter method is "convenient when it works", but it does not always work - there are bugs there somewhere. The simplest is to change settings so that the file is just downloaded like any other type of file, and you open acrobat after the whole file is there. You can also change a setting in Adobe reader such that it does not try to show you partially downloaded files ("fast web view") until the download completes. I have had that trouble in the past, and solved it by both of these methods at different times.

Continues to abort at 11 MB point on "save link target file as"... It is still trying, but linking back through the net seems unlikely. It could be my ISP having a limit.

I'll have to capture a website and see if there is a download maximum file size. But then even that are increments of x K bytes and not the whole. Hum.

I'll talk to my ISP and see if they filter - have virus checker shut off and still no help. Mart> >

I will see if I can edit the file and repost it for just the tester info.

Suggest making part 1 and part 2.

Copy file and call it part 1 and another part 2 Then in part 1 - delete pages after xx. In part 2 delete pages before xx - make sure we don't cut page xx out!

That is what I would do on these large ones.

A friend has it and is making a CD for me - but there are many in the same boat I suspect.
