Underwater welding using the plasma MIG method
- Technical Univ. of Clausthal (Germany)
The increasing demands made today on under water welding make continuous further development necessary, especially with regard to automation. The results presented here focus on the plasma-MIG method because of its technical advantages under atmospheric conditions. If a welding method is to be economic, it must waive the need for complete pressure isolation, i.e. hyperbar welding must be possible if the ambient pressure conditions so demand. Due to the fact that no reliable data was available to date on the process behavior of the plasma-MIG process, tests were carried out under increased pressure. This paper presents the results of the influence of pressure on the process and the formation of the seam geometry. Explanations are given on the structure of the arc zone which explain certain phenomena.
