Question

Ray Chown asked:

“With wet welding, if you didn’t have a dry environment, if you were trying to weld in the wet, how do those waterproof arc welding electrodes work?

Answer

We posed this question to Neil Woodward based at Cranfield University...


Neil - Yes, there has been a lot of work done with wet welding and there are issues with regard to the mechanical strength of wet welding and the depth capability of wet welding.  It does work very well in shallow waters with divers, but not really for deep water applications.
