Does anyone know of any guidance notes available for sub-merged arc welding and the likely hazards including any potentional health issues related to bacterial growth or welding rsidues that may be present in water tanks used for this process? I can't find any info on this apart from a brief process description on wikipedia.
Any help would be much appreciated,
Gav

Gavin,
Being stoopid, can you explain the process, my experience of submerged arc welding is the arc is submerged in flux, where does the water come into it? This has been discussed in detail on this forum before.

Hi sorry folks, meant to right atomic hydro welding under water. We sometimes need to add hard additional hard facing to a product after it has already been through the heat treat process and it is carried out submerged in a tank of water to reduce the heat exposure to the part from the additional welding.
I'm new to this so i'm not totally 100% on the processes yet.
Does that make it better for any advice?

Got you now and sorry beyond my experience, done welding, done heat treatment, done hard facing not done it all together! I wouldn't have thought you had any particular problems at those temperatures, with regular changes. You can also buy additives for this process. I would suggest you get your welding supplies rep' in they should be able to give you all the H&S and environmental info' you require, if not change your supplier you need competent support for this process.

submerged arc welding fume is hazardous to human health. As welding flux contains S and P, they get burnt and become certain gas, which may cause problem to respiratory system. so fume extraction is necessary. remember to protect yourself. here is more info about submerged arc welding. http://www.ylflux.com/
