We use broco rods. And we have several different methods for cutting including a method of kerrie cable which is a self consuming cable filled with oxygenLiferider. Short answer to your question is underwater welding is not arc welding. It uses self consuming method. You push the rod into the work. Also there is a proprietary metallurgy in the rod. Very high nickel content which helps keep the weld from becoming brittle.
