Abstract: To harness the high potential of the underwater application of drawn arc stud welding, a methodology for qualifying the process was developed. This includes a process evaluation based on electrical process parameters, a test method for determining the diffusible hydrogen content in the weld metal, and a method for evaluating the heterogeneous material behavior using quantitative microstructure analysis. Based on the findings and the application of the methodology, a semi-wet process was qualified and approprate weld joint properties were proven.
