Under Water Welding
(OP)
Can anyone tell me the maximum size of a single pass fillet weld performed under water? Also how much performance loss to expect from both single and multi-pass welds underwater?
Thanks

I think you would use an oxy-acetylene method of some sort... and I don't know what type of weld deposit you would be looking for.

Will the welding be done in a wet environment or a dry environment, at what depth and what is the welding process?

The welding will be wet at depths of 5' to 25'. The diver is saying 1/8" is the maximum size he can make. We were thinking 3/16 to 1/4 in a single pass. Never heard that multiple pass welds were out of the question before. Tried the Navy manual, but the downloaded file will not display beyond Chapter 2.

What is the diver basing his comments on ?
Is this the max amperage of his equipment,
Or is he worried about hydrogen embrittlement and cracking?

The good engineer does not need to memorize every formula; he just needs to know where he can find them when he needs them. Old professor

As far as I would be concerned the best approach is to have a welding procedure qualified by the welder under field conditions. This is the proof.
