Ladies/Gents Does anyone have an idea what the requirments are for a BOP (bead on plate) test in accordance with BS 7363 Type 2 Figure 9? I guess getting the BS spec would do the trick, but I am wondering what type of testing the BOP consists of. Thanks in advance
You might want to contact TWI (The Welding Institute) in the UK because, I have'nt been current with British standards any longer so I could'nt confidently answer your query... I do know that most, if not all BS welding standards have been superceded by EN standards... Here's their website: http://www.twi.co.uk/j32k/index.xtp
Here's the British version of our own forum only they're a bit more "rowdy" than ours at times and visa versa!!! Here's where you might get a good response with regards to your query: http://www.ukwelder.com/
This one is the British Institute of Non Destructive Testing but, I do'nt know if it will help much: http://www.bindt.org/
anywho, that's all I've got for now... I'll post if I find out anything new! ;)
Generally speaking a BOP test is a Vickers hardness survey performed in the HAZ just under the weld of a single bead. This is a test aimed at producing the highest obtainable hardness that may be produced at a particular heat input.
Sorry, I don't know the max hardness value. It depends on the material being welded.
