Battelle Test

[Guest102023]

I'm looking to learn more about this test, about which I can only find sketchy information on the interweb.
I understand it is applied to HSLA and low alloy steels and seems designed to forced HAZ cracking.
Is it still used, and how useful is it?
Thanks in advance.

I am really dating myself but I believe it is the drop weight tear test developed at Battelle to evaluate notch toughness of weldments. Look it up.

Drop weight tear testing is an excellent but expensive method to evaluate full thickness toughness properties.

Thanks, I have some familiarity with DWTT, but have never heard it referred to as the "Battelle Test".

This may also be one of the restraint welding tests to be used to determine susceptibility to hydrogen cracking. Battelle did have one of these tests.

weldstan,
My research tells me that is the test I am looking for. Can you tell me any more about it?

Probably the Keyhole Slotted Plate Restraint Test. I cannot provide more info as it has been over 35 years since I was somewhat familiar with it. It was developer by Battelle.

Look it up on the Web.

Um, I did google this, as I always would before asking here. But if it happened after 1998 the interweb can be pretty ignorant.

I found it on the WEB by typing in keyhole slotted plate restraint test - battelle.
